0b7d48d106 nptl: Move sem_close, sem_open into libc
The symbols were moved using move-symbol-to-libc.py.

Both functions are moved at the same time because they depend
on internal functions in sysdeps/pthread/sem_routines.c, which
are moved in this commit as well.  Additional hidden prototypes
are required to avoid check-localplt failures.

7dd416491e linux: Fix __sem_check_add_mapping search_sem
Similar to __sem_check_add_mapping fix, take in consideration the
trailling NULL.

Checked x86_64-linux-gnu.

e99156816d linux: Fix __sem_check_add_mapping name length
Take in consideration the trailling NULL since sem_search uses
strcmp to compare entries.

Checked on x86_64-linux-gnu and powerpc-linux-gnu (where it triggered
a nptl/tst-sem7 regression).

c1f46f9db7 pthread: Remove alloca usage from __sem_check_add_mapping
sem_open already returns EINVAL for input names larger than NAME_MAX,
so it can assume the largest name length with tfind.

Checked on x86_64-linux-gnu.

da4aea0b5e pthread: Refactor semaphore code
The internal semaphore list code is moved to a specific file,
sem_routine.c, and the internal usage is simplified to only two
functions (one to insert a new semaphore and one to remove it
from the internal list).  There is no need to expose the
internal locking, neither how the semaphore mapping is implemented.

No functional or semantic change is expected, tested on
x86_64-linux-gnu.
