- Rewrite BufferOutputStream to handle 0 sized buffers and to get rid
of an unnecessary loop.
- Add tests to verify overflow corner cases.
- Implement async_safe_format_buffer to call async_safe_format_buffer_va_list
instead of duplicate the code.
Test: Ran new unit tests, booted on angler.

Library calls like system() and popen() invoke the shell executable
pointed to by '_PATH_BSHELL' in order to run the command passed into the
function. The _PATH_BSHELL points to /system/bin/sh by default and thus
breaks any vendor process trying to use system() / popen(), as they are
denied access to system shell by selinux.
This CL make necessary changes, so the implmentations of system() and popen()
can use the appropriate shell (e.g. /vendor/bin/sh for processes running
out of /vendor partition). Also, changes the implementation of system()
and popen().
Bug: 64832610
Test: Manual, Using a test program running from /system/bin and
/vendor/bin to ensure correct shell is being used.

(cherry picked from commit aa3e32422c)
FORTIFY's *_chk functions mess with ASAN's library function
interceptors, which can apparently result in false-positives.
Since adding even more complexity to every run-time check condition in
FORTIFY doesn't seem like a great idea, and the majority of our builds
will still use FORTIFY anyway, turning FORTIFY off here seems
reasonable.

Test: checkbuild on internal master + CtsBionicTestCases. No new
failures.

pthread's and semaphore's default behavior is to use CLOCK_REALTIME,
however this behavior is essentially never intended, as that clock is
prone to change discontinuously.
What users really intend is to use CLOCK_MONOTONIC, however only
pthread_cond_timedwait() provides this as an option and even there, a
large amount of existing code does not opt into CLOCK_MONOTONIC.
We have seen numerous bugs directly attributable to this difference.
Therefore, we provide this general workaround to always use
CLOCK_MONOTONIC for waiting, regardless of what the input timespec
is.
Specifically this impacts the below APIs:
pthread_mutex_timedlock()
pthread_cond_timedwait()
pthread_rwlock_timedrdlock()
pthread_rwlock_timedwrlock()
sem_timedwait()
Test: boot bullhead, boot sailfish
Test: bionic pthread/semaphore unit tests
Test: check that pthread_cond_timedwait() timeouts are uneffected by
CLOCK_REALTIME time changes

'visible' flag was interpreted only the namespaces other than 'default'.
The flag has to be handled without exception once it is set.
Bug: 63411330
Test: Build and boot without errors.
Test: Add `namespace.default.visible = true` to [vendor] process in
'ld.config.txt' and reboot the device.

GCC's FORTIFY required optimizations to be enabled in order to function
properly. Clang's FORTIFY doesn't have this limitation, so it seems
pointless to keep it disabled due to a GCC-specific limitation.

The versioner doesn't handle C++ blocks yet, so these guards won't be
added and it will appear as though the functions are always available
in C++, but based on API level in C.
Test: make checkbuild
