Remove check for working malloc_set_state

This check was added to 'malloc_initialize_hook' in order to "insulate
Emacs better from configuration screwups" (commit b4788b9394f3).  With
unexec gone, we no longer use 'malloc_set_state', and thus don't need
this check.

Note that this patch removes the last uses of the deprecated glibc
functions 'malloc_set_state' and 'malloc_get_state' from our code.

* src/alloc.c (malloc_initialize_hook) [DOUG_LEA_MALLOC]:
Remove check for working 'malloc_set_state'.

Eglot: symbol highlighting now done in eldoc-documentation-functions

Even though highlighting the thing at point isn't really producing
documentation at point, theory and practice have shown that using
eldoc-documentation-functions for this is a feasible way to avoid
reimplementing all the idle timer logic for such functionality.

In fact, we were already using ElDoc for this purpose, but this commit
makes it so the new eglot-highlight-eldoc-function is a first class
citizen in eldoc-documentation-functions, so users can manipulate it if
so desired.

* lisp/progmodes/eglot.el (eglot--managed-mode): Use
eglot-highlight-eldoc-function
(eglot-hover-eldoc-function): Don't mix highlighting with hover.
(eglot-highlight-eldoc-function): Rename and rework from
eglot--highlight-piggyback

Make vmessage a bit safer

* src/xdisp.c (vmessage): Avoid undefined behavior if
FRAME_MESSAGE_BUF_SIZE (f) is zero, or if doprnt generates output
containing only encoding errors.  Although it’s not clear whether
either is possible, it is better to be safe.  Also, clarify via a
new local message_bufsize.

Pacify -Wanalyzer-use-of-uninitialized-value

With ‘configure --enable-gcc-warnings’,
gcc (GCC) 14.2.1 20250110 (Red Hat 14.2.1-7) on x86-64
complained, as it apparently did not want to assume that enum
variables have one of the listed values.
Work around the problem by using tables rather than
switch statements.  This gives up a little static
checking but I don’t see any other easy way to pacify
GCC without disabling the warnings entirely.
* src/pdumper.c (dump_fwd_int, dump_fwd_bool, dump_fwd_obj)
(dump_fwd_buffer_obj, dump_fwd_kboard_obj):
Last arg is now void const * so that these functions’ addresses
can all be put into the same array.
(dump_fwd, dump_anonymous_allocate_posix, dump_map_file_posix):
Use an array rather than a switch.
(mem_prot_posix_table): New static constant table.

Fix unlikely eassert failure in invalid_radix_integer

Fix unlikely eassert failure in pgtk_enumerate_devices

* src/pgtkterm.c (pgtk_enumerate_devices): Prefer
make_formatted_string to snprintf + build_string + eassert, as
it’s simpler and won’t crash Emacs if the eassert fails.

(cherry picked from commit 901659bb7046bef4ca10490cf47644fb2bc6d753)

Minor format_string tuneup

* src/comp.c (format_string): Prefer strcpy to doing things by hand
in a place where strcpy is easier to read, generates
more-efficient code, and similar parts of Emacs do strcpy.

Ignore -fanalyzer-null-argument in pgtkterm.c

* src/pgtkterm.c: Ignore -Wanalyzer-null-dereference.
I don’t have time to look into all the diagnostics,
but the ones I checked seemed to be false alarms with
gcc -std=gnu23 on x86-64, and we are ignoring this
diagnostic in other modules.  This is GCC 14.2.1
20250110 (Red Hat 14.2.1-7).

Pacify -fanalyzer-null-argument on pgtk_term_init

Protect against GCing of last_mouse_window

* src/window.c (last_mouse_window): New global var.  All static
instances removed, and all their uses replaced with this global
var.  This fixes a very unlikely bug where last_mouse_window was
GC’ed and a new window created in its place.  It also fixes several
places that assumed NIL_IS_ZERO without static_asserting it.
(init_window_once): Initialize the new var.

char **.  Omit last arg.  All callers changed.  Simplify
allocation to pacify GCC 14.2.1 complaint about malloc size
mismatching size of array: there’s no need for an extra byte when
converting from ldata to idata.
(selection_data_to_lisp_data): Third arg is now void const *,
not unsigned char const *.  All callers changed.
Omit unnecessary casts.  Make some locals more local.
