* config/threads-no.h: Remove file.
* config/threads-posix.h: Remove file.
* acconfig.h (_GLIBCPP_USE_THREADS): Remove.
(_GLIBCPP_SUPPORTS_WEAK): Add (required by namespace-clean gthr*.h).
(_GLIBCPP_HAVE_GTHR_DEFAULT): Likewise.
* config.h.in: Regenerate.
* acinclude.m4 (GLIBCPP_ENABLE_THREADS): Completely rework to
setup and use gthr*.h files. In particular, make gthr.h files
namespace-clean in the staging area (they don't have to be for
libgcc.a).
* aclocal.m4: Regenerate.
* configure: Regenerate.
* src/Makefile.am (build_headers): Remove bits/c++threads.h
and add bits/gthr.h bits/gthr-single.h bits/gthr-default.h.
* src/Makefile.in: Regenerate.
* include/bits/c++config: Cleanup threading configuration macros.
In particular, define __STL_GTHREADS macro which controls...
* include/bits/stl_threads.h: ...a brand new gthr.h-based
configuration here.
* config/c_io_stdio.h: Include staged gthr.h instead of local
thread configuration file. Always use __gthread_mutex_t
instead of __mutext_type (or int).
* include/bits/std_fstream.h: Likewise.
* docs/html/17_intro/howto.html: Remove placeholder comment in
case this configuration patch didn't make it. Add advice that
section only applies if configured with --enable-threads.
* docs/html/23_containers/howto.html: Reword to make clear
that _PTHREADS is no longer required for any port to be
correctly using STL with threads. Add advice that section
only applies if configured with --enable-threads.
