meson: Drop the .fa library suffix

The non-standard .fa library suffix breaks the link source
de-duplication done by Meson so drop it.

The lack of link source de-duplication causes AddressSanitizer to
complain ODR violations, and makes GNU ld abort when combined with
clang's LTO.

Fortunately, the non-standard suffix is not necessary anymore for
two reasons.

First, the non-standard suffix was necessary for fork-fuzzing.
Meson wraps all standard-suffixed libraries with --start-group and
--end-group. This made a fork-fuzz.ld linker script wrapped as well and
broke builds. Commit d2e6f9272d33 ("fuzz: remove fork-fuzzing
scaffolding") dropped fork-fuzzing so we can now restore the standard
suffix.

Second, the libraries are not even built anymore, because it is
possible to just use the object files directly via extract_all_objects().

The occurences of the suffix were detected and removed by performing
a tree-wide search with 'fa' and .fa (note the quotes and dot).

Those functions are not needed, one remove function should already

Here the code doesn't really care about whether we need to keep that dupfd
around if close() failed: when that happens something got very wrong,
keeping the dup_fd around the fdsets may not help that situation so far.

stubs/meson: Fix qemuutil build when --disable-system

Compiling without system, user, tools or guest-agent fails with the
following error message:

./configure --disable-system --disable-user --disable-tools \

error message:

collect2: error: ld returned 1 exit status

This is because tests/bench and tests/unit both need qemuutil, which
requires error_vprintf stub when system is disabled.

Add error_vprintf stub into stub_ss for all cases other than disabling
system.

monitor: remove MonitorDef from typedefs.h

MonitorDef is defined by hmp-target.h, and all users except one already
include it; the reason why the stubs do not include it, is because
hmp-target.h currently can only be used in files that are compiled
per target. However, that is easily fixed. Because the benefit of
having MonitorDef in typedefs.h is very small, do it and remove the
type from typedefs.h.
