libstdc++/2071
* porting.texi: Add documentation about libstdc++-v3-specific
macros that are currently included in os_defines.h files.
* config/basic_file_stdio.h (sys_getc): New method.
(sys_ungetc): New method.
* include/bits/basic_file.h: (sys_getc): New method signature.
(sys_ungetc): New method signature.
* include/bits/fstream.tcc (underflow): Add conditional code
paths which avoid using short seeks on streams (especially
useful when the stream might be interactive or a pipe). At
the moment, this alternate path only avoids seeking when the
``buffer size'' of underflow() is 1 since the C standard only
guarantees buffer space for one ungetc (this technique could
be extended since *-*-solaris* supports buffering for 4 calls
to ungetc and *-*-*bsd* supports buffering limited only by
memory resources). Also, _GLIBCPP_AVOID_FSEEK must be defined
in a port's os_defines.h file for this alternate path to even
be considered. As a bonus, the idiom of using getc/ungetc
requires no system calls whereas fseek maps to one or two
system call(s) on many platforms.
* config/os/bsd/freebsd/bits/os_defines.h (_GLIBCPP_AVOID_FSEEK):
Define it.
* config/os/solaris/solaris2.5/bits/os_defines.h
(_GLIBCPP_AVOID_FSEEK): Likewise.
* config/os/solaris/solaris2.6/bits/os_defines.h
(_GLIBCPP_AVOID_FSEEK): Likewise.
* config/os/solaris/solaris2.7/bits/os_defines.h
(_GLIBCPP_AVOID_FSEEK): Likewise.

* acinclude.m4 (GLIBCPP_ENABLE_THREADS): Completely rework to
setup and use gthr*.h files. In particular, make gthr.h files

libgcc.a).

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.
