Move shared pthread definitions to common headers

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).

	* posix/Makefile (headers): Add pthreadtypes-arch.h and
	thread-shared-types.h.

	specific thread definition.

+/* Arch-specific definitions.  Each architecture must define the following
+   macros to define the expected sizes of pthread data types:
+
+   __SIZEOF_PTHREAD_ATTR_T        - size of pthread_attr_t.
+   __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_CONDATTR_T    - size of pthread_condattr_t.
+   __SIZEOF_PTHREAD_RWLOCK_T      - size of pthread_rwlock_t.
+   __SIZEOF_PTHREAD_RWLOCKATTR_T  - size of pthread_rwlockattr_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)
+   must be defined.
