This is the patch I intend to push, I just finishing up the build on multiple
architecture to grab any missing issue.  I fixed the wording you pointed out
in previous review.

I decided to use my definition which uses the macros '__spins' and '__elision', 
since they are already being used in architecture that support lock elision.
My view is with current constraint and architecture duplication of definitions
it simplifies a bit the mutex definition. I think in the future, if
architecture internal definition code differentiate more (such as for
pthread_rwlock_t definition) we can move them to the new arch specific
headers.

I have added two new macros, __LOCK_ALIGNMENT and __ONCE_ALIGNMENT, to
grasp this idea and replicate their usage in the patch.

This patch removes all the replicated pthread definition accross the
architectures and consolidates it on shared headers.  The new
organization is as follow:

  * Architecture specific definition (such as pthread types sizes) are
    place in the new pthreadtypes-arch.h header in arch specific path.

  * All shared structure definition are moved to a common NPTL header
    at sysdeps/nptl/bits/pthreadtypes.h (with now includes the arch
    specific one for internal definitions).

  * Also, for C11 future thread support, both mutex and condition
    definition are placed in a common header at
    sysdeps/nptl/bits/thread-shared-types.h.

It is also a refactor patch without expected functional changes.
Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu,
arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu,
m68k-linux-gnu, microblaze-linux-gnu, mips{64}-linux-gnu, nios2-linux-gnu,
powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu,
tile{pro,gx}-linux-gnu, and x86_64-linux-gnu).

+   __SIZEOF_PTHREAD_MUTEX_T       - size of pthread_mutex_t.
+   __SIZEOF_PTHREAD_MUTEXATTR_T   - size of pthread_mutexattr_t.
+   __SIZEOF_PTHREAD_COND_T        - size of pthread_cond_t.

+   __SIZEOF_PTHREAD_BARRIER_T     - size of pthread_barrier_t.
+   __SIZEOF_PTHREAD_BARRIERATTR_T - size of pthread_barrierattr_t.
+
+   Also, the following macros must be define for internal pthread_mutex_t
+   struct definitions (struct __pthread_mutex_s):
+
+   __PTHREAD_COMPAT_PADDING_MID   - any additional members after 'kind'
+				    and before '__spin' (for 64 bits) or
+				    '__nusers' (for 32 bits).
+   __PTHREAD_COMPAT_PADDING_END   - any additional members at the end of
+				    the internal structure.
+   __PTHREAD_MUTEX_LOCK_ELISION   - 1 if the architecture supports lock
+				    elision or 0 otherwise.
+
+   The additional macro defines any constraint for the lock alignment
+   inside the thread structures:
+
+   __LOCK_ALIGNMENT - for internal lock/futex usage.
+
+   Same idea but for the once locking primitive:
+
+   __ONCE_ALIGNMENT - for pthread_once_t/once_flag definition.
+
+   And finally the internal pthread_rwlock_t (struct __pthread_rwlock_arch_t)
