The FREE_LIST_*_MT stuff was introduced on the SVN trunk in r28722
(2013-07-04), but so far, has not been merged into the v1.7 branch yet
(2013-09-06). So put it in its own #ifdef, rather than defining it
based on OMPI_MAJOR_VERSION/OMPI_MINOR_VERSION.

The Cisco-maintained v1.6 port of the usnic BTL has diverged from the
upstream trunk and v1.7 branches. This commit adjusts the trunk to more
closely match the v1.6 branch to simplify future merging and
cherry-picking.
The usnic MCA parameters also need work on this side.

The fix for the HPL SEGV was incorrect because it assumed the
prepare_src() routine was always allowed to return "bytes processed"
less than the requested "bytes to send". It turns out this is only true
if the convertor is what limits the size, we are not allowed to limit
the data sent for our own reasons, else we break login in the upper
layers.
This means we need to learn the number of bytes out of the size
requested the convertor will give us, no matter how big the size is.
Unfortunately, this is a destructive test, and (currently) the only way to
learn that number is to actually have the convertor copy the data out into
buffers.
This change implements this, copying the entire data out into a chain of
send segments which are attached to the large send fragment. Now we can
always return the proper size value to the PML.

- split some routines into an inline fast section and a called
slower section
- introduce receive fastpath in component_progress that:
o returns immediately if there is a packet available on priority
queue and fastpath is enabled
o disables fastpath for 1 time after use to provide fairness to
other processing
o defers receive buffer posting
o defers bookeeping for receive until next call

Without this, an `--enable-debug` build would hit an assertion in the
list code when run under valgrind with `--malloc-fill=0xff` or any other
case where malloc returned non-zeroed buffers.
Also allow the normal OBJ_ machinery to handle the constructor
invocation ordering for us instead of doing it by hand (which could have
led to future bugs).

configure-time dynamic allocation of flags. The net result for platforms
which only support BTL-based communication is a reduction of 8*nprocs bytes
per process. Platforms which support both MTLs and BTLs will not see
a space reduction, but will now be able to safely run both the MTL and BTL
side-by-side, which will prove useful.

The free list code called the constructor for each object it
slab allocated in ompi_free_list_grow. This permits free list-managed
elements to safely allocate/deallocate resources in their
constructors/destructors without leaking.
It's probably best to let this soak on the trunk a little while before
moving it over to v1.7.

Calling OMPI_REQUEST_INIT puts the request into an _INACTIVE state
instead of an _INVALID state, which we don't want if it's been
simply been constructed, e.g., in a free_list. Without this change a
future change to call destructors at free list destruction time will
result in request dtor state assertion failures.

the output of ompi_info.
A variable is disabled if its component will never be selected due to
a component selection parameter (eg. -mca btl self). The old behavior
of ompi_info was to not print these parameters at all. Now we print the
parameters. After some discussion with George it was decided that there
needed to be some way to see what parameters will not be used. This was
the comprimise.
This commit also fixes a bug and a typo in the pvar sytem. The enum_count
value in mca_base_pvar_dump was being used without being set. The full_name
in mca_base_pvar_t was not being used.

endpoint_rfstart was being initialized from a value which was not yet
set. Also ensure that rfstart is a valid index in the range
0..WINDOW_SIZE-1, since it is used as the index into endpoint_rcvd_segs,
which has WINDOW_SIZE elements.
Without this change there is significant risk of memory corruption or
segfaults, resulting in hangs or crashes, if malloc ever returns us a
value >=WINDOW_SIZE (4096). Right now we seem to be getting lucky that
the malloc is returning zero-pages to us when we are allocating endpoint
structures (possibly because the freelist performs a single large
allocation for all endpoints).
