* src/augprint.c: Fix reallocarray warnings
GCC 14.2.1 gives lots of warnings of this sort about the order of
parameters of reallocarray being the wrong way round:
augprint.c: In function ‘find_or_create_group’:
augprint.c:462:60: error: ‘reallocarray’ sizes specified with ‘sizeof’ in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
462 | all_groups_realloc = reallocarray(all_groups, sizeof(struct group *), num_groups_newsize);
| ^~~~~~
augprint.c:462:60: note: earlier argument should specify number of elements, later size of each element

* acinclude.m4: Disable -Winline warnings
GCC 14.2.1 gives warnings like:
In file included from memory.h:26,
from augmatch.c:30:
In function ‘guess_lens_name’,
inlined from ‘main’ at augmatch.c:396:16:
internal.h:229:19: error: inlining failed in call to ‘streqv’: call is unlikely and code size would grow [-Werror=inline]
229 | static inline int streqv(const char *a, const char *b) {
| ^~~~~~
augmatch.c:294:9: note: called from here
294 | if (streqv(ext, ".json")) {
| ^~~~~~~~~~~~~~~~~~~~
These warnings don't seem very useful in Augeas, since we are not so
sensitive to code size and don't care about inlining "purity". Rather
than attempting to "fix" code which isn't really broken, I chose to
disable an unhelpful warning.

* src/get.c: Disable false GCC warning
GCC 14.2.1 doesn't seem to be able to analyze this stack frame code
correctly. When compiling augeas with --enable-compile-warnings=error
that causes the build to fail with the errors below. Disable the
error around this code.
In file included from /usr/include/string.h:548,
from ../gnulib/lib/string.h:41,
from internal.h:31,
from get.c:30:

If you disable -Warray-bounds only then you get this instead:
