Fix bug 370.

Remove unused function.

declare _init/_fini weak if UCLIBC_CTOR_DTOR is not defined

Fix bug 430 and reduce ldso size with 1KB :). Not sure if I need to use fstat64, but I am sure someone will
tell me.

Add atomic support for PPC.
Merge glibc bits/atomic.h powerpc32/bits/atomic.h powerpc64/bits/atomic.h into one file

Change to glibc way of defining syscalls. This should make PPC
compile with gcc 4.0/4.1

make sure we treat count as size_t, not ssize_t ... fixes with help from khem

syntax/whitespace touchups

Basically, the uClinux dist includes a few thread demos - thdm and bcdm -
running them simultaneously sometimes causes bus errors.

This patch was made against our cvs, which has an older version of uClibc
in it - this code was recently moved from internals.h to descr.h in the
uclibc svn, but it still has the same problem

remove duplicated p_canceled setting and extra whitespace

sync style changes and misc fixes from glibc

sync some style changes and stack fixes with glibc

sync with glibc and macro out the strong_alias/versioned-symbols to cut down on the diffs

newer linuxthreads renamed the function invalid_handle() to nonexisting_handle()

sync with glibc by moving the thread_desc stuff out of internals.h and into a new file descr.h ... also redo thread_desc init by specifying members in the struct by name rather than position

revert pthread_exit change until all files using new prototype is ready

sync all the strong_alias and version compat stuff but make them no-ops with #if magic to cut down on diffs

add hidden_def() macros from glibc but stub them out to cut down on diffs

sync prototypes with glibc

punt wrapsyscall.c as glibc has

make sure we use optimized version when building for newer intel/amd cpus

import some fixes from glibc

sync with glibc and import pthread_rwlock_timed{rd,wr}lock in the process

uClibc has pthread_attr_{get,set}stack now

sync misc trivial touchups from glibc
