This reduces the amount of boilerplate for these tests, and ensures that
we have a corresponding swprintf() test for every snprintf() test
(except the handful where it doesn't make sense; we have no FORTIFY for
the wide-character routine, for example).

Jens Gustedt suggested a better implementation last year on the musl
mailing list: https://www.openwall.com/lists/musl/2022/11/19/1
It means the constants are sparse, but in return it means we can add
future constants and they'll be backward compatible. (Sadly you'll need
to be on API level 35 before you can use anything but TIME_UTC.)
I doubt this will ever matter, because everyone should just stick to
clock_gettime()/clock_getres() anyway, and anyone who does have a
legitimate use for timespec_get() and timespec_getres() probably needs
to support non-Linux and so can't use any clocks that aren't in ISO C
anyway. But given that we don't _have_ to paint ourselves into a corner
here, we may as well take the opportunity to not do so.

This is the one openlog() flag that toybox uses. We should probably try
to unify toybox's POSIX logger and Android-specific log at some point,
and this will help.
Also fix our behavior with an empty format string, noticed while adding
tests.

wfN: Specifies that a following b, d, i, o, u, x, or X conversion specifier applies to a fastest minimum-width integer argument with a specific width where N is a positive decimal integer with no leading zeros (the argument will have been promoted according to the integer promotions, but its value shall be converted to the unpromoted type); or that a following n conversion specifier applies to a pointer to a fastest minimum-width integer type argument with a width of N bits. All fastest minimum-width integer types (7.22.1.3) defined in the header <stdint.h> shall be supported. Other supported values of N are implementation-defined.

changes the way overflows are tracked: now compiler builtins
are used instead of manual arithmetics. But as int_fast32_t on
64-bit Android takes 8 bytes, new logic behaves differently.
See time_test.cpp changes for more details.

1) Checkout tzcode repo
2) Prepare patches for all tzcode file using

When annotating the netinet directory aosp/2552567, we realize the
argment s for vsnprintf family can be null only if the buffer size is 0.
So we correct them and add some tests to verify our assumption.

Nothing to see here --- you'll want to keep using POSIX clock_gettime()
and clock_getres() instead. But portable code might use this eventually,
and it's trivial, so let's add it anyway.
(The whole "zero as an error return" precluding the direct use of
Linux's CLOCK_ constants is what really makes this a terrible API ---
we're going to have to add explicit translation any time they add a
new base.)

Contrary to the old comment, POSIX says nothing about whether or not
tmpfile() respects $TMPDIR, and it's significantly more useful on
Android if it does (because there's no shared /tmp that everyone can
write to).

This mode instructs the linker to search for libraries in hwasan
subdirectories of all library search paths. This is set up to contain a
hwasan-enabled copy of libc, which is needed for HWASan programs to
operate. There are two ways this mode can be enabled:
* for native binaries, by using the linker_hwasan64 symlink as its
interpreter
* for apps: by setting the LD_HWASAN environment variable in wrap.sh

The recent header nullability additions and the corresponding source
cleanup made me notice that we're missing a couple of actions that most
of the other implementations have. They've also been added to the _next_
revision of POSIX, unchanged except for the removal of the `_np` suffix.
They're trivial to implement, the testing is quite simple too, and
if they're going to be in POSIX soon, having them accessible in older
versions of Android via __RENAME() seems useful. (No-one else has shipped
the POSIX names yet.)

Now <utmpx.h> isn't any more useful on Android than <utmp.h> is, but it
is POSIX, and -- importantly -- we can implement it with just a header
file, so code can use it on every existing API level.
macOS does indeed only have the <utmpx.h> functions (although it does
still have the <utmp.h> header!), so potentially portable code might
want <utmpx.h> on Android. (glibc/musl both have both headers.)

Test: atest bionic-unit-tests (in presubmit)
This test was flaky because there was no synchronization between the end
of the test function scope and the jumper threads, resulting in a racy
use-after-scope when accessing the thread array. Fix it by joining the
threads before leaving the test function scope.
Replace the thread array access, which can race with the store to the
thread array in the main thread, with an access to a pre-initialized
variable, which acts as a kind of enforcement that the threads are done
before leaving the test.
