[svn-r10769] Fixed definition of builtin info object MPI_INFO_ENV to be consistent with other builtin objects.  Fixes #1762.  Reviewd by Balaji

Reviewer: buntinas

Added a paremeter to enable/disable the RMA lock-op-unlock merging
optimization.

[svn-r10759] Update the trmem routines and macros (defined when malloc took an unsigned int for size) to use size_t instead, as well as some int/size_t cleanup (again for code that correctly used signed int when it was written)

This assertion was made unnecessary by previous cleanups.  It was re-checking
the branch condition, and could thus never fail.

we can't keep up and are giving up, instead of hanging.

Updated existing request-generating RMA ops test to verify that communication
with PROC_NULL is handled correctly.

Reviewer: goodell

This patch more efficiently handles request-generating operations that target
the local process and MPI_PROC_NULL.  These special cases return completed
generalized requests, which cost less overhead.  This also makes space for a
more efficient implementation when direct, shared memory operations are
implemented.

Reviewer: goodell

Note: Request-generating operations can only be called within a passive target
epoch.

Reviewer: goodell

When called with a target process of PROC_NULL, RMA request-generating
operations did not return a valid request handle.

Reviewer: goodell

Many RMA tests did not limit their output when an error occurred.  This adds
the simple SQUELCH() macro to these tests to limit per-process error messages.
