The initial reason to write this patch was to remove the last use of
CONFIG_DEBUG_TCG from the makefiles; the flags to use to build TCG
plugins are unrelated to --enable-debug-tcg, and instead they should
be the same as those used to build emulators (the plugins are not build
via meson for demonstration reasons only).
However, since contrib/plugins/Makefile is also the last case of doing
a compilation job using config-host.mak, go a step further and make it
use a completely separate configuration file, removing all references
to compilers from the toplevel config-host.mak. Clean up references to
empty variables, and use .SECONDARY so that intermediate object files
are not deleted.

Implement the virtio-gpu feature in contrib/vhost-user-gpu, which was
unsupported until now.
In this implementation, the feature is enabled inconditionally to avoid
creating another optional config argument.
Similarly to get_display_info, vhost-user-gpu sends a message back to
the frontend to have access to all the display information. In the
case of get_edid, it also needs to pass which scanout we should
retrieve the edid for.
The VHOST_USER_GPU_PROTOCOL_F_EDID protocol feature is required if the
frontend sets the VIRTIO_GPU_F_EDID virtio-gpu feature. If the frontend
sets the virtio-gpu feature but does not support the protocol feature,
the backend will abort with an error.

It was hard to track down this leak as it was an internal allocation
by glib and the backtraces did not give much away. The autofree was
freeing the allocation with g_free() but not taking care of the
individual strings. They should have been freed with g_strfreev()
instead.
Searching the glib source code for the correct string free function
led to:
G_DEFINE_AUTO_CLEANUP_FREE_FUNC(GStrv, g_strfreev, NULL)
and indeed if you read to the bottom of the documentation page you
will find:
typedef gchar** GStrv;
A typedef alias for gchar**. This is mostly useful when used together with g_auto().
So fix up all the g_autofree g_strsplit case that smugly thought they
had de-allocation covered.

It's already confusing that we have two very similar functions for
wrapping the parse of a 64-bit unsigned value, differing mainly on
whether they permit leading '-'. Adjust the signature of parse_uint()
and parse_uint_full() to be like all of qemu_strto*(): put the result
parameter last, use the same types (uint64_t and unsigned long long
have the same width, but are not always the same type), and mark
endptr const (this latter change only affects the rare caller of
parse_uint). Adjust all callers in the tree.
While at it, note that since cutils.c already includes:
QEMU_BUILD_BUG_ON(sizeof(int64_t) != sizeof(long long));
we are guaranteed that the result of parse_uint* cannot exceed
UINT64_MAX (or the build would have failed), so we can drop
pre-existing dead comparisons in opts-visitor.c that were never false.

QEMU adds the path to glib.h to all compilation commands. This is simpler
due to the pervasive use of static_library, and was grandfathered in from
the previous Make-based build system. Until Meson 0.63 the only way to
do this was to detect glib in configure and use add_project_arguments,
but now it is possible to use add_project_dependencies instead.
gmodule is detected in a separate variable, with export enabled for
modules and disabled for plugin.

Commit 747421e949 ("Implements Backend
Program conventions for vhost-user-scsi") introduced fd-passing support
as part of implementing the vhost-user backend program conventions.
When fd passing is used the UNIX domain socket path is NULL and we must
not call unlink(2).
The unlink(2) call is necessary when the listen socket, lsock, was
created successfully since that means the UNIX domain socket is visible
in the file system.

Over time, those functions where used with Win32 SOCKET or

used with socket-like file-descriptors. FDs can use
g_unix_set_fd_nonblocking() instead.
Rename the functions with "socket" in the name to prevent bad usages.

This adds an implementation of a simple L2 configuration, in which a
unified L2 cache (stores both blocks of instructions and data) is
maintained for each core separately, with no inter-core interaction
taken in account. The L2 cache is used as a backup for L1 and is only
accessed if the wanted block does not exist in L1.
In terms of multi-threaded user-space emulation, the same approximation
of L1 is done, a static number of caches is maintained, and each and
every memory access initiated by a thread will have to go through one of
the available caches.
An atomic increment is used to maintain the number of L2 misses per
instruction.
The default cache parameters of L2 caches is:
2MB cache size
16-way associativity
64-byte blocks

Multicore L1 cache modelling is introduced and is supported for both
full system emulation and linux-user.
For full-system emulation, L1 icache and dcache are maintained for each
available core, since this information is exposed to the plugin through
`qemu_plugin_n_vcpus()`.
For linux-user, a static number of cores is assumed (default 1 core, and
can be provided as a plugin argument `cores=N`). Every memory access
goes through one of these caches, this approach is taken as it's
somewhat akin to what happens on real setup, where a program that
dispatches more threads than the available cores, they'll thrash
each other
