Add the missing prototypes, fix the existing prototypes to use clockid_t
rather than int, fix clock_nanosleep's failure behavior, and add simple
tests.

Use $(BUILD_SYSTEM)/base_rules to build it as custom module, so that
it's exposed to utilities like mm/mmma etc.

The trouble with cp is that if you're running a command directly (because
you're using gdb, say), you need to make sure you've copied the linker
and shell again if you've done a rebuild that caused a change there.

Otherwise the gcc compiler warning doesn't show up.
Add -Wno-error to fortify related tests. Fortify related tests
are expected to be examples of bad programs, and in many
cases shouldn't compile cleanly. Rewriting them to compile
cleanly isn't feasible nor desirable.

Otherwise the gcc compiler warning doesn't show up.
Delete some unittests. These unittests no longer compile cleanly
using -Wall -Werror, and rewriting them to compile cleanly
isn't feasible.

Unlike times(), clock_gettime() is implemented as a vDSO on many architectures.
So, using clock_gettime() will return a more accurate time and do so with less
overhead because it does have the overhead of calling into the kernel.
It is also significantly more accurate because it measures the actual time in
nanoseconds rather than the number of ticks (typically 1 millisecond or more).

The previous pthread_key_create_many test was really
pthread_key_create_all, which has proven very difficult to test
correctly (because it is affected by any other parts of the system using
pthread keys, and that can vary with test ordering). It also tested
expected values of PTHREAD_KEYS_MAX and the associated sysconf() value,
rather than those being in their own test.
Instead, split this test into a few distinct tests:
* pthread.pthread_keys_max
* pthread._SC_THREAD_KEYS_MAX_big_enough_for_POSIX
* pthread.pthread_key_many_distinct
* We actually didn't have a test to ensure that the keys we were
creating were distinct.
* pthread.pthread_key_EAGAIN
* Make sure pthread_key_create() will _eventually_ fail with
EAGAIN, not at a (sometimes incorrectly) predetermined maximum.

libc and libc++ both define std::nothrow. libc's is a private symbol,
but this still causes issues when linking libc.a and libc++.a, since
private isn't effective until it has been linked. To fix this, just
allow multiple symbol definitions for the static tests.

From C99 standard: “The nextafter functions determine the next representable value, in the type of the function,
after x in the direction of y, where x and y are first converted to the type of the function”.
The next representable value of 0.0 in direction of -1.0 is -4.9406564584124654e-324, not 0.0.
Similar thing holds for nextafterf, nextafterl, nexttowardf, nexttoward, and nexttowardl.
The tests pass either way, since the error is within the tolerance, but how it is written is wrong.

There are number of changes in the way IFUNC related relocations are done:
1. IRELATIVE relocations are now supported for x86/x86_64 and arm64.
2. IFUNC relocations are now relying on static linker to generate
them in correct order - this removes necessety of additional
relocation pass for ifuncs.
3. Related to 2: rela?.dyn relocations are preformed before .plt ones.
4. Ifunc are resolved on symbol lookup this approach allowed to avoid
mprotect(PROT_WRITE) call on r-x program segments.
