This name better reflects that it handles arrays, and doesn't shout.

lib/, src/, tests/: Move x*() definitions to non-x* header files
...
Now that all of these are one-liners, they don't need a separate header
file. Compact stuff.

*/: Fix including <config.h> as system header
...
"config.h" is a locally generated header. It must be included as
'#include "config.h"'.
It is already included correctly in some sources files. This commit
unifies the way how "config.h" is included.

lib/string/sprintf/, tests/unit/: Transform x[v]asprintf() into x[v]aprintf()
...
Wrap [v]aprintf() instead of [v]asprintf(3).
Repurpose x[v]asprintf()'s tests to test x[v]aprintf().

lib/string/sprintf/: [v]aprintf(): Add functions
...
These functions are just like [v]asprintf(3), but simpler.
They return the newly allocated memory, which allows us to use the
[[gnu::malloc(free)]] attribute, which enhances static analysis.
They also omit the length, which we don't care about at all.
As a curiosity, Plan9 seems to provide this same API, under the name
smprint(3).

lib/, src/, tests/: Use the standard countof() instead of our NITEMS()
...
countof() is the name blessed by the C Committee for ISO C2y.
Use it if available, and define it if not.
countof() will be provided by GCC 16 and Clang 21.
This is mostly a scripted change:
$ grep -rl NITEMS | xargs sed -i s/NITEMS/countof/;
Apart from the scripted changes, I've adjusted white-space alignment,
and of course the definition at "lib/sizeof.h".
