use a single libc and deduplicate threading code

Similar to musl libc a single libc has many benefits and solves
some open issues with uClibc-ng.

- no pthread_mutex_* weak symbols exported anymore
- applications no longer failing to link when either
  -lrt or -lpthread are missing for dynamic and static linking mode
- smaller C library
- slightly better runtime performance

-vda: here is why:
-headers contain libc_hidden_proto(foo).
-In libpthread/linuxthreads/sysdeps/pthread/bits/libc-lock.h
-adding libc_hidden_proto(foo) just before weak_extern (__pthread_initialize)
-will not warn:
-    /* libc_hidden_proto(foo) */
-    weak_extern (__pthread_initialize)
-    /* libc_hidden_proto(foo) */
-but adding after will! Which is extremely strange -
-weak_extern expands into just "#pragma weak __pthread_initialize".
-TODO: determine whether it is a gcc bug or what
-(see gcc.gnu.org/PR36282).
-For now, just include all headers before internals.h
-(they are again included in internals.h - maybe remove them there later)
