This commit disables the linux patcher component due to a limitation
in loader patching. While this component is effective in patching
calls made within Open MPI and by the application it fails to hook
calls made within glibc. This means the munmap call made by free is
not correctly hooked. Until this problem can be resolved this
component will remain disabled. If it can't be resolved this component
should probably be removed.

The table of contents (TOC) code only appears to only apply to
ppc64. The code was incorrectly assuming the existence of the TOC on
ppc32. This commit updates the necessary code to only apply to ppc64.

This commit fixes a compile/link issue caused by vader. The vader btl
was using OPAL_THREAD_ADD64 to increment a counter which may not be
available on 32-bit systems. Changed to use OPAL_THREAD_ADD_SIZE_T
which will be 64-bit or 32-bit depending on the system.

ebx can not be clobbered when using -fPIC so save and restore the
register instead of allowing it to be clobbered.

instead of doing AC_CHECK_HEADERS+AC_CHECK_LIB and only using the result of the former.
Thanks to Paul Hargrove for reporting the issue (OMPI build with -m32).

This commit fixes a compilation issue with some versions of exp
verbs. In some cases struct ibv_exp_device_attr does not have either
the exp_atom or exp_atomic_cap fields. It is fine to drop one check
and fall back to the non-exp attribute check on the other.

Add a feature check for clflush before trying to use the clflush
instruction. As far as I can tell there is no equivalent before the
SSE2 instruction set.

HCOLL barrier may not complete if HCOLL progress is not called periodically.
which is the case in HCOLL teardown progress in the finalize.

This commit fixes a bad synchronization detection bug that occurs when
mixing MPI_Win_fence() and MPI_Win_lock(). If no communication has
occurred in the fence epoch it is safe to just clear the all_sync
object (it was set up by fence).

The function signature of mremap on BSD (NetBSD, FreeBSD) differs from
the linux version. Added support for the BSD style of mremap.

This commit fixes a compile error when the system has mremap but not
MREMAP_FIXED. In this case we do not care about the value of
new_address as the argument does not exist.

In some rare cases when a process receives the connect ack while
locally updating the peer endpoint structure, we could drop the
incomming connect ack due to the fact that the send handler is
protected with a try lock (on the endpoint) and our initial send
event was not persistent. Making the send event persistent solves
all issues.
When building an empty datatype (aka. size = 0) because the count of
included datatypes is 0, be less strict on what the arguments are
(allow NULL pointers).
