mentioned in the comment the completion/callback of the triggered
send operation can happen before the call returns. If this happens and
if the pipeline depth is 0 before we triggered the send operation and
this is the last send operation of the request then the completion detection
code will decrement the pipeline depth and check it for equality to 0.
Because (0-1) != 0 the pml completion function for this request will
*not* be called.
This part 2 of the fix for ticket #246.

all platforms. The only exceptions (and I will not deal with them
anytime soon) are on Windows:
- the write functions which require the length to be an int when it's
a size_t on all UNIX variants.
- all iovec manipulation functions where the iov_len is again an int
when it's a size_t on most of the UNIXes.
As these only happens on Windows, so I think we're set for now :)

size and diplacement of data-type. After this patch all data can contain size_t bytes
and the displacements are defined as ptrdiff_t. All of the files I was able to compile
have been modified to match this requirement.

The UD BTL isn't gone - the latest version is in my afriedle-ud branch. This version on the trunk was very old, ompi_ignore'd, lacked performance, and probably contained bugs. The maintained version on my branch is working solid, and will eventually come back, but not for v1.2.

constrained:
* Make sure we always have a number of eager fragments available
that scales with the number of processes communicating with
a given proc over shared memory
* Use FREE_LIST_GET instead of FREE_LIST_WAIT to return an
error to the PML when resource exhaustion occurs
* Don't dereference the frag during alloc unless we're sure
it's not NULL

First, move the OPAL_THREAD_LOCK out to the same level as its corresponding UNLOCK. It was possible to hit the UNLOCK without ever acquiring the lock.
Since the OPAL_THREAD_ADD64() is now protected by this lock, we can just do the decrement non-atomically.

Don't try to acquire ompi_request_lock here, which in all cases is already held. Avoids deadlock that occurs even when threads are enabled and we're running a THREAD_SINGLE app.
