Create a new header lwp_private.h to contain _lwp_getprivate_fast,
_lwp_gettcb_fast, _lwp_settcb and remove them from mcontext.h, so that:
1. we don't need special hacks to hide them
2. we can include <lwp.h> where needed to get the necessary prototypes
   without redefining them locally.

Turn on _UC_TLSBASE for sure in the same manner as other ports.
No functional changes since that flag is turned on via getcontext(2).

sync with head

Make lint happy.
While here, make sure the top of stack is aligned properly.

Add PPC TLS support.  Add -D_LIBC_SOURCE for tls.c and _lwp.c (powerpc)
so that __lwp_gettcb_fast and __lwp_settcb inlines are define.

Sync with HEAD

Allow storing and receiving the LWP private pointer via ucontext_t
on all platforms except VAX and IA64. Add fast access via register for
AMD64, i386 and SH3 ports. Use this fast access in libpthread to replace
the stack based pthread_self(). Implement skeleton support for Alpha,
HPPA, PowerPC, SPARC and SPARC64, but leave it disabled.

Ports that support this feature provide __HAVE____LWP_GETPRIVATE_FAST in
machine/types.h and a corresponding __lwp_getprivate_fast in
machine/mcontext.h.

This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

Add missing __RCSID()

Make sure we reference getcontext() by its internal name.

Merge the nathanw_sa branch.

_lwp_makecontext()

file _lwp.c was initially added on branch nathanw_sa.
