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.
