configure: replace --enable/disable-git-update with --with-git-submodules
Replace the --enable-git-update and --disable-git-update configure params
with the param --with-git-submodules=(update|validate|ignore) to
allow 3 options for building from a git repo.
This is needed because downstream packagers, e.g. Debian, Ubuntu, etc,
also keep the source code in git, but do not want to enable the
'git_update' mode; with the current code, that's not possible even
if the downstream package specifies --disable-git-update.
The previous parameters are deprecated but still available; the
--enable-git-update parameter maps to --with-git-submodules=update and
--disable-git-update parameter maps to --with-git-submodules=validate.
The configure script behavior is slightly modified, where previously
the dtc, capstone, and slirp submodules were not validated when
--disable-git-update was specified (but were updated with git-update
enabled), now they are validated when using --with-git-submodules=validate
and are only ignored when using --with-git-submodules=ignore.

ui/sdl2 : initial port to SDL 2.0 (v2.0)
I've ported the SDL1.2 code over, and rewritten it to use the SDL2 interface.
The biggest changes were in the input handling, where SDL2 has done a major
overhaul, and I've had to include a generated translation file to get from
SDL2 codes back to qemu compatible ones. I'm still not sure how the keyboard
layout code works in qemu, so there may be further work if someone can point
me a test case that works with SDL1.2 and doesn't with SDL2.
Some SDL env vars we used to set are no longer used by SDL2,
Windows, OSX support is untested,
I don't think we can link to SDL1.2 and SDL2 at the same time, so I felt
using --with-sdlabi=2.0 to select the new code should be fine, like how
gtk does it.
v1.1: fix keys in text console
v1.2: fix shutdown, cleanups a bit of code, support ARGB cursor
v2.0: merge the SDL multihead patch into this, g_new the number of consoles
needed, wrap DCL inside per-console structure.

Fixes & improvements by kraxel:
* baum build fix
* remove text console logic
* adapt to new input core
* codestyle fixups

configure: replace --enable/disable-git-update with --with-git-submodules
Replace the --enable-git-update and --disable-git-update configure params
with the param --with-git-submodules=(update|validate|ignore) to
allow 3 options for building from a git repo.
This is needed because downstream packagers, e.g. Debian, Ubuntu, etc,
also keep the source code in git, but do not want to enable the
'git_update' mode; with the current code, that's not possible even
if the downstream package specifies --disable-git-update.
The previous parameters are deprecated but still available; the
--enable-git-update parameter maps to --with-git-submodules=update and
--disable-git-update parameter maps to --with-git-submodules=validate.
The configure script behavior is slightly modified, where previously
the dtc, capstone, and slirp submodules were not validated when
--disable-git-update was specified (but were updated with git-update
enabled), now they are validated when using --with-git-submodules=validate
and are only ignored when using --with-git-submodules=ignore.

configure: replace --enable/disable-git-update with --with-git-submodules
Replace the --enable-git-update and --disable-git-update configure params
with the param --with-git-submodules=(update|validate|ignore) to
allow 3 options for building from a git repo.
This is needed because downstream packagers, e.g. Debian, Ubuntu, etc,
also keep the source code in git, but do not want to enable the
'git_update' mode; with the current code, that's not possible even
if the downstream package specifies --disable-git-update.
The previous parameters are deprecated but still available; the
--enable-git-update parameter maps to --with-git-submodules=update and
--disable-git-update parameter maps to --with-git-submodules=validate.
The configure script behavior is slightly modified, where previously
the dtc, capstone, and slirp submodules were not validated when
--disable-git-update was specified (but were updated with git-update
enabled), now they are validated when using --with-git-submodules=validate
and are only ignored when using --with-git-submodules=ignore.

configure: Add a test for the minimum compiler version
So far we only had implicit requirements for the minimum compiler version,
e.g. we require at least GCC 4.1 for the support of atomics. However,
such old compiler versions are not tested anymore by the developers, so
they are not really supported anymore. Since we recently declared explicitly
what platforms we intend to support, we can also get more explicit on the
compiler version now. The supported distributions use the following version
of GCC:
RHEL-7: 4.8.5
Debian (Stretch): 6.3.0
Debian (Jessie): 4.8.4
OpenBSD (ports): 4.9.4
FreeBSD (ports): 8.2.0
OpenSUSE Leap 15: 7.3.1
Ubuntu (Xenial): 5.3.1
macOS (Homebrew): 8.2.0
So we can safely assume GCC 4.8 these days. For Clang, the situation is
a little bit more ambiguous, since it is sometimes not available in the
main distros but rather third party repositories. At least Debian Jessie
uses version 3.5, and EPEL7 for RHEL7 uses 3.4, so let's use 3.4 as
minimum Clang version now - we still can adjust this later if necessary.
Unfortunately Apple uses different version numbers for the Clang that is
included in their Xcode suite, so we need to check the version numbers
for Xcode separately. Xcode 5.1 seems to be the first one that has been
shipped with LLVM 3.4, so use this version as the minimum there.

build-sys: clean up flags included in the linker command line
Some of the CFLAGS that are discovered during configure, for example
compiler warnings, are being included on the linker command line because
QEMU_CFLAGS is added to it. Other flags, such as the -m32, appear twice
because they are included in both QEMU_CFLAGS and LDFLAGS. All this
leads to confusion with respect to what goes in which Makefile variables
(and we have plenty).
So, introduce QEMU_LDFLAGS for flags discovered by configure, following
the lead of QEMU_CFLAGS, and stop adding to it:
1) options that are already in CFLAGS, for example "-g"
2) duplicate options
At the same time, options that _are_ needed by both compiler and linker
must now be added to both QEMU_CFLAGS and QEMU_LDFLAGS, which is clearer.
This is mostly -fsanitize options. For now, --extra-cflags has this behavior
(but --extra-cxxflags does not).
Meson will not include CFLAGS on the linker command line, do the same in our
build system as well.

plugins: do not limit exported symbols if modules are active
On Mac --enable-modules and --enable-plugins are currently incompatible, because the
Apple -Wl,-exported_symbols_list command line options prevents the export of any
symbols needed by the modules. On x86 -Wl,--dynamic-list does not have this effect,
but only because the -Wl,--export-dynamic option provided by gmodule-2.0.pc overrides
it. On Apple there is no -Wl,--export-dynamic, because it is the default, and thus
no override.
Either way, when modules are active there is no reason to include the plugin_ldflags.
While at it, avoid the useless -Wl,--export-dynamic when --enable-plugins is
specified but --enable-modules is not; this way, the GNU and Apple configurations
are more similar.

build-sys: clean up flags included in the linker command line
Some of the CFLAGS that are discovered during configure, for example
compiler warnings, are being included on the linker command line because
QEMU_CFLAGS is added to it. Other flags, such as the -m32, appear twice
because they are included in both QEMU_CFLAGS and LDFLAGS. All this
leads to confusion with respect to what goes in which Makefile variables
(and we have plenty).
So, introduce QEMU_LDFLAGS for flags discovered by configure, following
the lead of QEMU_CFLAGS, and stop adding to it:
1) options that are already in CFLAGS, for example "-g"
2) duplicate options
At the same time, options that _are_ needed by both compiler and linker
must now be added to both QEMU_CFLAGS and QEMU_LDFLAGS, which is clearer.
This is mostly -fsanitize options. For now, --extra-cflags has this behavior
(but --extra-cxxflags does not).
Meson will not include CFLAGS on the linker command line, do the same in our
build system as well.

build-sys: clean up flags included in the linker command line
Some of the CFLAGS that are discovered during configure, for example
compiler warnings, are being included on the linker command line because
QEMU_CFLAGS is added to it. Other flags, such as the -m32, appear twice
because they are included in both QEMU_CFLAGS and LDFLAGS. All this
leads to confusion with respect to what goes in which Makefile variables
(and we have plenty).
So, introduce QEMU_LDFLAGS for flags discovered by configure, following
the lead of QEMU_CFLAGS, and stop adding to it:
1) options that are already in CFLAGS, for example "-g"
2) duplicate options
At the same time, options that _are_ needed by both compiler and linker
must now be added to both QEMU_CFLAGS and QEMU_LDFLAGS, which is clearer.
This is mostly -fsanitize options. For now, --extra-cflags has this behavior
(but --extra-cxxflags does not).
Meson will not include CFLAGS on the linker command line, do the same in our
build system as well.

configure: replace --enable/disable-git-update with --with-git-submodules
Replace the --enable-git-update and --disable-git-update configure params
with the param --with-git-submodules=(update|validate|ignore) to
allow 3 options for building from a git repo.
This is needed because downstream packagers, e.g. Debian, Ubuntu, etc,
also keep the source code in git, but do not want to enable the
'git_update' mode; with the current code, that's not possible even
if the downstream package specifies --disable-git-update.
The previous parameters are deprecated but still available; the
--enable-git-update parameter maps to --with-git-submodules=update and
--disable-git-update parameter maps to --with-git-submodules=validate.
The configure script behavior is slightly modified, where previously
the dtc, capstone, and slirp submodules were not validated when
--disable-git-update was specified (but were updated with git-update
enabled), now they are validated when using --with-git-submodules=validate
and are only ignored when using --with-git-submodules=ignore.

configure: preserve various environment variables in config.status
The config.status script is auto-generated by configure upon
completion. The intention is that config.status can be later invoked by
the developer directly, or by make indirectly, to re-detect the same
environment that configure originally used.
The current config.status script, however, only contains a record of the
command line arguments to configure. Various environment variables have
an effect on what configure will find. In particular PKG_CONFIG_LIBDIR &
PKG_CONFIG_PATH vars will affect what libraries pkg-config finds. The
PATH var will affect what toolchain binaries and XXXX-config scripts are
found. The LD_LIBRARY_PATH var will affect what libraries are
found. Most commands have env variables that will override the name/path
of the default version configure finds.
All these key env variables should be recorded in the config.status script.
Autoconf would also preserve CFLAGS, LDFLAGS, LIBS, CPPFLAGS, but QEMU
deals with those differently, expecting extra flags to be set using
configure args, rather than env variables. At the end of the script we
also don't have the original values of those env vars, as we modify them
during configure.

configure: preserve various environment variables in config.status
The config.status script is auto-generated by configure upon
completion. The intention is that config.status can be later invoked by
the developer directly, or by make indirectly, to re-detect the same
environment that configure originally used.
The current config.status script, however, only contains a record of the
command line arguments to configure. Various environment variables have
an effect on what configure will find. In particular PKG_CONFIG_LIBDIR &
PKG_CONFIG_PATH vars will affect what libraries pkg-config finds. The
PATH var will affect what toolchain binaries and XXXX-config scripts are
found. The LD_LIBRARY_PATH var will affect what libraries are
found. Most commands have env variables that will override the name/path
of the default version configure finds.
All these key env variables should be recorded in the config.status script.
Autoconf would also preserve CFLAGS, LDFLAGS, LIBS, CPPFLAGS, but QEMU
deals with those differently, expecting extra flags to be set using
configure args, rather than env variables. At the end of the script we
also don't have the original values of those env vars, as we modify them
during configure.
