lower the default priority to 0 so that it's not active unless you
specifically ask for it (this component needs more testing by people
other than me before we unleash it on the public).

Try to detect which form this version of Open IB uses, defaulting to the 5
version if we can't figure it out (the new version has 5 params)
* Only add -lcm if it exists on the system - some versions of Open IB
apparently don't need it.

searching the tree. Modified the memory callback to search the tree at each
page boundary for registrations. This is necessary as an application may
malloc memory and send out of any portion of that memory, even discontiguous
regions.

add misc asserts to check for proper reference counting.
ugly hack 1 -- use mallopt to never release memory ala sbrk - this is
commented out in mca_btl_mvapi_component_init
ugly hack 2 -- test registrations comming out of the tree via rcache_find, for
an unknown reason the tree is returning registrations where the address is not
within the base or bound of the registration. If this happens, we return
NULL.
comment out code to enable mem hooks if leave_pinned is set, note we can do
this via an mca param and will default it to leave_pinned with mem_hooks when
we iron out these issues.
I am adding a unit test for the rcache. Note that we have a unit test for the
rb tree but the compare function is significantly different than that used for
registrations. After we have tracked down the issues with rcache_rb we will
remove the above hacks.

Red Storm is complaining about invalid memory pointer (need to go back
to Linux and look at this with valgrind)
* Turn off send in place for now, so I can run the tests on RS and see if
everything else is ok
This commit was SVN r7497.
* fix dumb bug in btl_portals_get where I using the dest descriptor key instead
of the source descriptor key for the match bits, resulting in a PtlGet() with
the wrong match bits

need to remove old ones from the front
- call deregister to actually remove items from the cache/mru
list and deregister the memory (if not being used)

be used in MPI_Alloc_mem operations. Note that we found an interesting bug in
which if memory was allocated by the sm mpool (via mmap) and then registered
via the mvapi mpool, the registration would fail on certain systems.
Added mca param mpool_base_use_mem_hooks, set to 1 to enable the memory hooks
so that memory is deregistered if the user frees it behind our back. This is
only useful if the mca param mpi_leave_pinned is also set to 1. Otherwise all
registrations are deregistered within the MPI library or via
MPI_Free_buf. After testing we should probably set both mpi_leave_pinned and
mpool_base_use_mem_hooks to default to 1.
