doesn't seem to be sufficient in some cases.

The proxies trap PMI calls and multiplex them over a single connection
to the main PMI server. This reduces the number of fd resources used,
which is useful for large-scale systems. This can also potentially
allow the proxies to perform some intelligent tasks, such as caching,
in the future. This can possibly have a small performance penalty for
small scale systems, because of an additional forwarding, but should
be negligible.

[svn-r6117] Update the debugger interface to use the new match structure; also update Makefile.sm to handle the fact that MPICH2 now requires additional libraries beyong the MPILIBNAME libraries

[svn-r6115] Use a defined typedef for the message match information; this is needed by the debugger interface

not necessary, but is convenient for some debugger libraries such as
padb.

[svn-r6105] Adding MPL to VS projs and updating the windows configure script and makefiles accordingly - MPL was added in r6054

and we are asked to do nothing (MPI_INFO_NULL passed in)

This commit moves the existing tracing memory allocation and valgrind
code utilities to MPL.  This permits other code like gforker to use the
trmem code while allowing MPICH2 to remain thread-safe when using
tracing.  gforker is not updated to the MPL routines by this commit.
