[PULL 1/4] overall: Remove unnecessary g_strdup_printf() calls

[Michael Tokarev]

From: Philippe Mathieu-Daudé <philmd@linaro.org>

Replace g_strdup_printf("%s", value) -> g_strdup(value)
to avoid unnecessary string formatting.

[PULL 2/4] qemu/timer: Clarify timer_new*() must be freed with timer_free()

[Michael Tokarev]

From: Philippe Mathieu-Daudé <philmd@linaro.org>

There was not mention QEMUTimer created with timer_new*() must
be released with timer_free() instead of g_free(), because then
active timers are removed from the active list. Update the
documentation mentioning timer_free().

[PULL 4/4] make-release: don't rely on $CWD when excluding subproject directories

[Michael Tokarev]

From: Michael Roth <michael.roth@amd.com>

The current logic scans qemu.git/subprojects/ from *.wrap files to
determine whether or not to include the associated directories in the
release tarballs. However, the script assumes that it is being run from
the top-level of the source directory, which may not always be the case.
In particular, when generating releases via, e.g.:

  make qemu-9.2.1.tar.xz

the $CWD will either be an arbitrary external build directory, or
qemu.git/build, and the exclusions will not be processed as expected.
Fix this by using the $src parameter passed to the script as the root
directory for the various subproject/ paths referenced by this logic.

Also, the error case at the beginning of the subproject_dir() will not
result in the error message being printed, and will instead produce an
error message about "error" not being a valid command. Fix this by using
basic shell commands.
