This test traverses the QOM sub-tree rooted at /machine. Traverse the
entire tree instead.
The x86_64 test runs some 40 additional QMP commands, and stays under
5s for me.

This test traverses the QOM sub-tree rooted at /machine with a
combination of qom-list and qom-get. In my x86_64 testing, it runs
almost 12000 QMP commands in 34 seconds. With -m slow, we test more
machines, and it takes almost 84000 commands in almost four minutes.
Since commit 3dd93992ff (tests/qtest/qom-test: unit test for
qom-list-get), the test traverses this tree a second time, with
qom-list-get. In my x86_64 testing, this takes some 200 QMP commands
and around two seconds, and some 1100 in just under 12s with -m slow.
Traversing the entire tree is useful, because it exercise the QOM
property getters. Traversing it twice not so much.
Make the qom-list / qom-get test shallow unless -m slow is given:
don't recurse. Cuts the number of commands to around 600, and run
time to under 5s for me.

qio_channel_socket_connect_sync() returns 0 on success, and -1 on
failure, with errp set. Some callers check the return value, and some
check whether errp was set.
For consistency, always check the return value, and always check it's
negative.

QGA-VSS writes error using error_setg_win32_internal,
which call g_win32_error_message.
g_win32_error_message - translate a Win32 error code
(as returned by GetLastError()) into the corresponding message.
In the same time, we call error_setg_win32_internal with
error codes from different Windows componets like VSS or
Performance monitor that provides different codes and
can't be converted with g_win32_error_message. In this
case, the empty suffix will be returned so error will be
masked.
This commit directly add hex value of error code.
Reproduce:
- Run QGA command: {"execute": "guest-fsfreeze-freeze-list", "arguments": {"mountpoints": ["D:"]}}
QGA error example:
- before changes:
{"error": {"class": "GenericError", "desc": "failed to add D: to snapshot set: "}}
- after changes:
{"error": {"class": "GenericError", "desc": "failed to add D: to snapshot set: Windows error 0x8004230e: "}}

In this function we could have this variable not initialized. If this
could be acceptable on error, the variable could be left not initialized
f.e. as follows:
void requester_freeze(int *num_vols, void *mountpoints, ErrorSet *errset)
{
...
if (mountpoints) {
...
if (num_mount_points == 0) {
/* If there is no valid mount points, just exit. */
goto out;
}
}
...
if (!mountpoints) {
...
if (num_fixed_drives == 0) {
goto out; /* If there is no fixed drive, just exit. */
}
}
...
}
Stay on safe side, initialize the variable at the beginning.

When compiling QEMU with --enable-ubsan there is a undefined behavior
warning when running "make check":
.../qga/commands-linux.c:452:15: runtime error: applying non-zero offset 5 to null pointer
#0 0x55ea7b89450c in build_guest_fsinfo_for_pci_dev ..../qga/commands-linux.c:452:15
Fix it by avoiding the additional pointer variable here and use an
"offset" integer variable instead.

parse_keyboard_layout() passes a possibly null @filename to
trace_keymap_parse(). Trace backend log then formats it with %s,
which crashes on some systems.
Fix by moving the null check before the trace_keymap_parse().
While there, improve the error messages a bit.
Fixes: d3b787fa7d (keymaps: add tracing)
