f17a42333f Do not use __ptr_t. 
sys/cdefs.h has a macro __ptr_t, which a few places in glibc use
instead of void *.  void * is a well-understood standard type for that
purpose and in a post-C89 context there is no need for a macro for it;
this patch changes those places to use void * directly instead.

Unlike __long_double_t, __ptr_t is widely used outside glibc (or at
least has many hits on codesearch.debian.net).  I don't know how many
of those uses would break if sys/cdefs.h ceased to define the macro,
but there's enough risk that this patch leaves the definition and just
removes the uses within glibc; removal of the definition can be
considered separately if desired.

Tested for x86_64, and with build-many-glibcs.py.

fa872e1b62 Clean pthread functions namespaces for C11 threads 
This patch adds internal definition (through {libc_}hidden_{proto,def}) and
also change some strong to weak alias for symbols that might be used by C11
threads implementations.

The patchset should not change libc/libpthread functional, although object
changes are expected (since now internal symbols are used instead) and final
exported symbols through GLIBC_PRIVATE is also expanded (to cover libpthread
usage of __mmap{64}, __munmap, __mprotect).

Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu,
arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu,
microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu,
powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu,
tile{pro,gx}-linux-gnu, and x86_64-linux-gnu).
