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

Sync with glibc, quietens gcc warnings.

This drops __signed, __volatile, and __const. Only the latter was
used in the code base, and for uClibc, not consistently. Much of
the code used plain "const" which meant "__const" was useless.
Really, the point of this is to stay in sync with what glibc did.

This matches a similar change made to glibc.
No functional changes here.

NPTL build did not use the correct bits/sigthread.h, use a common version
avoiding this.

Stdio locking macroes do:
void *__self = THREAD_SELF;
But THREAD_SELF uses __self also internally which causes shadowing
warnings. Just rename the outer variable for now. Might be an idea
to convert the macroes to static inline functions.

It is not possible to override for libpthread to override
the weak libc definitions. This has never worked in uclibc, and
does no longer work in glibc either (unless you use LD_DYNAMIC_WEAK).
The proper thing to do is have weak prototypes in libc, and
definitions in libpthread only. This way libc runs even if
those functions are not defined, but just needs to protect
against the NULL values (done by implementing __uclibc_maybe_call).
This fix the problems if libc is linked before libpthread or
if libpthread is pulled by a dependency library.
