The 'blacklist' argument / config key are deprecated since commit
582a098e6c ("qga: Replace 'blacklist' command line and config file
options by 'block-rpcs'"), time to remove them.

cec07c79a4 qga: Shorten several error messages
Some, but not all error messages are of the form

    Guest agent command failed, error was '<actual error message>'

For instance, command guest-exec can fail with an error message like

    Guest agent command failed, error was 'Failed to execute child process “/bin/invalid-cmd42” (No such file or directory)'

Shorten this to just just the actual error message.  The guest-exec
example becomes

    Failed to execute child process “/bin/invalid-cmd42” (No such file or directory)

ecfc9890c4 qga-win32: Improve guest-set-user-password, guest-file-open errors
When guest-set-user-password's argument @password can't be converted
from UTF-8 to UTF-16, we report something like

    Guest agent command failed, error was 'Invalid sequence in conversion input'

Improve this to

    can't convert 'password' to UTF-16: Invalid sequence in conversion input

Likewise for argument @username, and guest-file-open argument @path,
even though I'm not sure you can actually get invalid input past the
QMP core there.

0d8caac904 Bump minimum glib version to v2.66
Now that we dropped support for CentOS 8 and Ubuntu 20.04, we can
look into bumping the glib version to a new minimum for further
clean-ups. According to repology.org, available versions are:

 CentOS Stream 9:       2.66.7
 Debian 11:             2.66.8
 Fedora 38:             2.74.1
 Freebsd:               2.78.4
 Homebrew:              2.80.0
 Openbsd:               2.78.4
 OpenSuse leap 15.5:    2.70.5
 pkgsrc_current:        2.78.4
 Ubuntu 22.04:          2.72.1

Thus it should be safe to bump the minimum glib version to 2.66 now.
Version 2.66 comes with new functions for URI parsing which will
allow further clean-ups in the following patches.

Since commit 246d76eba ("qga: guest_suspend: decoupling pm-utils and sys
logic") pm-utils logic is running in a separate child from the sysfs
logic.  Now when suspending via sysfs we don't really need to do that in
a separate process as we only need to perform one write to /sys/power/state.

Let's just use g_file_set_contents() to simplify things here.

c3f32c13a3 qga: introduce ga_run_command() helper for guest cmd execution
When executing guest commands in *nix environment, we repeat the same
fork/exec pattern multiple times.  Let's just separate it into a single
helper which would also be able to feed input data into the launched
process' stdin.  This way we can avoid code duplication.

To keep the history more bisectable, let's replace qmp commands
implementations one by one.  Also add G_GNUC_UNUSED attribute to the
helper and remove it in the next commit.

50761a5a9a qga: guest-get-fsinfo: add optional 'total-bytes-privileged' field
Since the commit 25b5ff1a86 ("qga: add mountpoint usage info to
GuestFilesystemInfo") we have 2 values reported in guest-get-fsinfo:
used = (f_blocks - f_bfree), total = (f_blocks - f_bfree + f_bavail) as
returned by statvfs(3).  While on Windows guests that's all we can get
with GetDiskFreeSpaceExA(), on POSIX guests we might also be interested in
total file system size, as it's visible for root user.  Let's add an
optional field 'total-bytes-privileged' to GuestFilesystemInfo struct,
which'd only be reported on POSIX and represent f_blocks value as returned
by statvfs(3).

While here, also tweak the docs to reflect better where those values
come from.

734e7b73df qga/commands-win32: Do not set matrix_lookup_t/win_10_0_t arrays size
ga_get_win_name() iterates over all elements in the arrays by
checking the 'version' field is non-NULL. Since the arrays are
guarded by a NULL terminating element, we don't need to specify
their size:

  static char *ga_get_win_name(...)
  {
      ...
      const ga_matrix_lookup_t *table = WIN_VERSION_MATRIX[tbl_idx];
      const ga_win_10_0_t *win_10_0_table = ...
      ...
      while (table->version != NULL) {
                    ^^^^^^^^^^^^^^^
              while (win_10_0_table->version != NULL) {
                                     ^^^^^^^^^^^^^^^

This will simplify maintenance when adding new entries to these
arrays.

Split WIN_VERSION_MATRIX into WIN_CLIENT_VERSION_MATRIX and
WIN_SERVER_VERSION_MATRIX because  multidimensional array must
have bounds for all dimensions except the first.

0cec50119f qapi: Require member documentation (with loophole)
The QAPI generator forces you to document your stuff.  Except for
command arguments, event data, and members of enum and object types:
these the generator silently "documents" as "Not documented".

We can't require proper documentation there without first fixing all
the offenders.  We've always had too many offenders to pull that off.
Right now, we have more than 500.  Worse, we seem to fix old ones no
faster than we add new ones: in the past year, we fixed 22 ones, but
added 26 new ones.

To help arrest the backsliding, make missing documentation an error
unless the command, type, or event is in listed in new pragma
documentation-exceptions.

in qga/.

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".

f897ef0d47 qapi: qga: Clarify when out-data and err-data are populated
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.

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.
