Markus Armbruster 3424ed6caf qga/qapi-schema: Move command description right after command name
Documentation of commands guest-ssh-get-authorized-keys,
guest-ssh-add-authorized-keys, and guest-ssh-remove-authorized-keys
describes the command's purpose after its arguments.  Everywhere else,
we do it the other way round.  Move it for consistency.

Peng Ji 7c4486350a qga-win: Fix guest-get-fsinfo multi-disks collection
When a volume has more than one disk, all disks cannot be
returned correctly because there is not enough malloced memory
for disk extents, so before executing DeviceIoControl for the
second time, get the correct size of the required memory space
to store all disk extents.

Paolo Bonzini 1220f5813a meson: remove config_targetos
config_targetos is now empty and can be removed; its use in sourcesets
that do not involve target-specific files can be replaced with an empty
dictionary.

In fact, at this point *all* sourcesets that do not involve
target-specific files are just glorified mutable arrays.  Enforce that
they never test for symbols in "when:" by computing the set of files
without "strict: false".

If output is being captured for a guest-exec invocation, the out-data
and err-data fields of guest-exec-status are only populated after the
process is reaped. This is somewhat counter intuitive and too late to
change. Thus, it would be good to document the behavior.

Daniel Xu d6f67b83b8 qga: Fix memory leak when output stream is unused
If capture-output is requested but one of the channels goes unused (eg.
we attempt to capture stderr but the command never writes to stderr), we
can leak memory.

guest_exec_output_watch() is (from what I understand) unconditionally
called for both streams if output capture is requested. The first call
will always pass the `p->size == p->length` check b/c both values are
0. Then GUEST_EXEC_IO_SIZE bytes will be allocated for the stream.

But when we reap the exited process there's a `gei->err.length > 0`
check to actually free the buffer. Which does not get run if the command
doesn't write to the stream.

Fix by making free() unconditional.

Daniel Xu 810f677ab8 qga: Add merged variant to GuestExecCaptureOutputMode
Currently, any captured output (via `capture-output`) is segregated into
separate GuestExecStatus fields (`out-data` and `err-data`). This means
that downstream consumers have no way to reassemble the captured data
back into the original stream.

This is relevant for chatty and semi-interactive (ie. read only) CLI
tools.  Such tools may deliberately interleave stdout and stderr for
visual effect. If segregated, the output becomes harder to visually
understand.

This commit adds a new enum variant to the GuestExecCaptureOutputMode
qapi to merge the output streams such that consumers can have a pristine
view of the original command output.

Konstantin Kostiuk 07ce178a2b qga/win32: Use rundll for VSS installation
The custom action uses cmd.exe to run VSS Service installation
and removal which causes an interactive command shell to spawn.
This shell can be used to execute any commands as a SYSTEM user.
Even if call qemu-ga.exe directly the interactive command shell
will be spawned as qemu-ga.exe is a console application and used
by users from the console as well as a service.

As VSS Service runs from DLL which contains the installer and
uninstaller code, it can be run directly by rundll32.exe without
any interactive command shell.

Add specific entry points for rundll which is just a wrapper
for COMRegister/COMUnregister functions with proper arguments.

Konstantin Kostiuk 88288c2a51 qga/win32: Remove change action from MSI installer
Remove the 'change' button from "Programs and Features" because it does
not checks if a user is an admin or not. The installer has no components
to choose from and always installs everything. So the 'change' button is
not obviously needed but can create a security issue.

Markus Armbruster c40233593e qga: Drop dangling reference to QERR_QGA_LOGGING_DISABLED
slog()'s function comment advises to use QERR_QGA_LOGGING_DISABLED.
This macro never existed.  The reference got added in commit
e3d4d25206 "guest agent: add guest agent RPCs/commands" along with
QERR_QGA_LOGGING_FAILED, so maybe that one was meant.  However,
QERR_QGA_LOGGING_FAILED was never actually used, and was removed in
commit d73f0beadb "qerror.h: Remove unused error classes".

Drop the dangling reference.

Markus Armbruster c12a984814 qga: Clean up includes
This commit was created with scripts/clean-includes.

All .c should include qemu/osdep.h first.  The script performs three
related cleanups:

* Ensure .c files include qemu/osdep.h first.
* Including it in a .h is redundant, since the .c  already includes
  it.  Drop such inclusions.
* Likewise, including headers qemu/osdep.h includes is redundant.
  Drop these, too.

Andrey Drobyshev 9ca180bce1 qga-win: choose the right libpcre version to include in MSI package
According to GLib changelog [1], since version 2.73.2 GLib is using
libpcre2 instead of libpcre.  As a result, qemu-ga MSI installation
fails due to missing DLL when linked with the newer GLib.

This commit makes wixl to put the right libpcre version into the MSI
bundle: either libpcre-1.dll or libpcre2-8-0.dll, depending on the
present version of GLib.

Andrey Drobyshev 8e86851bd6 qga: map GLib log levels to system levels
This patch translates GLib-specific log levels to system ones, so that
they may be used by both *nix syslog() (as a "priority" argument) and
Windows ReportEvent() (as a "wType" argument).

Currently the only codepath to write to "syslog" domain is slog()
function.  However, this patch allows the interface to be extended.

Note that since slog() is using G_LOG_LEVEL_INFO level, its behaviour
doesn't change.

Andrey Drobyshev f9f0e6173e qga-win: add logging to Windows event log
This commit allows QGA to write to Windows event log using Win32 API's
ReportEvent() [1], much like syslog() under *nix guests.

In order to generate log message definitions we use a very basic message
text file [2], so that every QGA's message gets ID 1.  The tools
"windmc" and "windres" respectively are used to generate ".rc" file and
COFF object file, and then the COFF file is linked into qemu-ga.exe.
