[PATCH] Get rid of > 35 GLIBC_PRIVATE unused exports

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

@GLIBC_PRIVATE symbols are not supposed to be used by anything outside
of glibc.  There is a lot of GLIBC_PRIVATE symbols which are not ever
used by the binaries or shared libraries included in glibc though
and IMHO it is just a waste to export them.
The majority are __libc_* exports which historically were used by
LinuxThreads libpthread.so, but as that now includes the ptw-*.os
objects which provide them they are no longer needed.

I believe LinuxThreads should use <not-cancel.h> interfaces instead
in a couple of places and will submit that change as a separate patch.
