4025874199 plugins: fix memory leak while parsing options
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.

f8ed3648b5 vhost-user: fully use new backend/frontend naming
Slave/master nomenclature was replaced with backend/frontend in commit
1fc19b6527 ("vhost-user: Adopt new backend naming")

This patch replaces all remaining uses of master and slave in the
codebase.

bd1386cce1 cutils: Adjust signature of parse_uint[_full]
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.

95caf1fb42 build: move warning flag selection to meson
Meson already knows to test with the positive form of the flag, which
simplifies the test.  Warnings are now tested explicitly for the C++
compiler, instead of hardcoding those that are only available for
the C language.

At this point all compiler flags in QEMU_CFLAGS are global and only
depend on the OS.  No feature tests are performed in configure.

fc9a809e0d build: move glib detection and workarounds to meson
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.

But in Windows Server 2022 memory dump this address space range is

is 'ntoskrnl.exe' actually.
So, introduce additional validation by checking image name from
Export Directory against 'ntoskrnl.exe'.

26ed501b99 contrib/vhost-user-blk: fix 32 bit build and enable
We were not building the vhost-user-blk server due to 32 bit
compilation problems. The problem was due to format string types so
fix that and then enable the build. Tweak the rule to follow the same
rules as other vhost-user daemons.

6852c21db2 vhost-user-scsi: avoid unlink(NULL) with fd passing
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.

ff5927baa7 util: rename qemu_*block() socket functions
The qemu_*block() functions are meant to be be used with sockets (the
win32 implementation expects SOCKET)

Over time, those functions where used with Win32 SOCKET or
file-descriptors interchangeably. But for portability, they must only be
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 is effectively reverting commit f9e8cacc55 ("oslib-posix:
rename socket_set_nonblock() to qemu_set_nonblock()").

8e3b0cbb72 Replace qemu_real_host_page variables with inlined functions
Replace the global variables with inlined helper functions. getpagesize() is very
likely annotated with a "const" function attribute (at least with glibc), and thus
optimization should apply even better.

This avoids the need for a constructor initialization too.

b21e238037 Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).
