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.

This automatically-generated patch converts 69 function definitions in
glibc from old-style K&R to prototype-style.
This patch, covering both sysdeps and non-sysdeps files, deals with
cases where the prototype needed to be wrapped over more than one
line. Otherwise, exclusions and caveats are as for
<https://sourceware.org/ml/libc-alpha/2015-10/msg00594.html> and
<https://sourceware.org/ml/libc-alpha/2015-10/msg00599.html>.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).
