Rework the pthread-stub design
The current design handles the most common use-cases, although it causes
breakage on others (when a pthreads liked library is dlopened). Refer to
the README for further details.
The new design, makes pthread-stubs a "meta" package which _never_
provides a library but only a .pc file.
pthread-stubs checks if the run-time (libc or otherwise) expose
lightweight pthread symbols to link against and defaults to a full blown
pthread.
This way projects can use the Cflags/Libs without having to know the
details. Alternatively they can directly link against the pthread
implementation, although that might bring unwarranted overhead.
v2:
- Remove m4 macro, always use -pthread and document why.
- Sort the symbol list, document how it's derived what is allowed and
what not.
- Rework the README to start from current state of afairs to past ones.
- Document platforms that are 'safe' and ones that are not.
v3:
- Add SVN note about -pthread + Cygwin/mingw/mingw-w64
