Add my initial work of libthread_db. The library is used by gdb to debug threaded process. Current, only libpthread is supported, but macrel will work on it to support libthr and libc_r.

# $FreeBSD$
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. 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. Tested on: amd64, i386, ia64

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.
