Brad correctly pointed out that the total window size should not be an
int. Changed it to an unsigned long.

Only one field is valid for RMA requests: MPI_ERROR. This field is set
to the correct value in ompi_request_empty so there is no reason to
allocate and keep track of osc/sm requests because they are always
complete on return. Since we are no longer using the osc/sm request
structure or free list they are now removed.
Closes trac:4723
Tracking this issue with the CMR. Brad, can you verify the issue is indeed fixed.

While testing one-sided on LANL systems I found a couple more OSC
bugs that were not caught during the initial testing:
- In the passive target code we read the read lock count as a
char instead of the intended uint32_t. This causes lock to
lockup when using shared locks after 127 iterations.
- The post code used the wrong group when trying to increment post
counters. This causes a segmentation fault.
- Both the post and wait code used the wrong check in the inner
loop leading to an infinite loop.

Fixed two bugs:
- Use module->comm NOT comm to get the CID for the shared memory backing
file. This fixes the case where there are multiple shared memory windows
at the same time.
- Remember to unlink the shared memory backing file.

Dave Goodell correctly pointed out that it is unusual to return MPI
error classes from internal ompi functions. Correct this in the RMA
case by adding an internal error code to match MPI_ERR_RMA_SYNC.
This does change OMPI_ERR_MAX. I don't think this will cause any
problems with ABI.

- Fix several typos is osc/rdma.
- Fix a locking issue in osc/sm that was caused by an incorrect
assumption about the semantics of opal_atomic_add_32.
- Always unlock the accumulation lock in osc/sm.
- The base of a processes shared memory window should be NULL if
the size is zero. Fixed.
