00fb440c1a Enable symbol versioning by default. Use WITHOUT_SYMVER to disable it. 
Warning, after symbol versioning is enabled, going back is not easy
(use WITHOUT_SYMVER at your own risk).

Change the default thread library to libthr.

There most likely still needs to be a version bump for at least the
thread libraries.  If necessary, this will happen later.

which means that we also have <thread_db.h>.

3475d7748a This library is not WARNS=2 clean for -O2 builds, because we include 
headers from libpthread that are not WARNS=2 clean for -O2 builds.
Lower the WARNS level to 1. This is the highest level possible for
now.

a7092d3091 Correct the mess I made by committing from the wrong tree. Most 
notably, this restores some of the contents in thread_db.h as well
as David Xu's copyright notice. This also fixes the includes in
the MD libpthread files which Scott tried to provide a quick fix
for.

3c1e38ea6e Add rudimentary support and stubs for libthr and libc_r on alpha, amd64, 
i386, ia64 and sparc64. Add stubs for alpha, amd64, ia64 and sparc64 for
libpthread.

Restructure the source files to avoid unnecessary use of subdirectories
that also force us to use non-portable compilation flags to deal with
the uncommon compilation requirements (building archive libraries for
linkage into a shared library).

The libpthread support has been copied from the original local and
cleaned-up to make them WARNS=2 clean.
