message from a known peer (not MPI_ANY_SOURCE) then we can attach the
remote proc and initialize the convertor as soon as we know the data-type,
and the count (so basically in the _INIT macro). If it's not the case, then
create them in the _MATCHED macro (as in the original version). Of course,
beforeinitializing the convertor we check that there will be some data
in the message.
This commit, plus the convertor improvements from few days ago, lower the
latency for my test case environment (mvapi) by 0.1 microseconds. The convertor
now is as slim as it can be, I don't think there is anything else to
remove/improve.

The following SVN revision numbers were found above:
r9005 --> open-mpi/ompi@20d06e889e
(1) As pointed out by Torsten after Jeff comment that there are 15 collectives yesterday.. nope.. I have 16 but
miss counted them in my ifdefs (I had two #11s). Replaces with enum...
(2) Added a readonly MCA param for how many backend algorithms are available per collective (used by benchmarker/STS)
This allowed me to remove the tuned query internal functions and replace them with ompi_coll_tuned_forced_max_algorithms[COLL].
(3) I was reading the user forced MCA params for the collectives on each comm create (module init) but I then put the
values into a global set of variables (like ompi_coll_tuned_reduce_forced_algorithm).
To fix this and make the code neater:
(a) The component looks up the MCA param indices on Open if dynamic_rules is set via the
ompi_coll_tuned_COLLECTIVE_intra_check_forced_init () call.
(b) Got rid of the ompi_coll_ompi_coll_tuned_COLLECTIVE_forced_algorithm/segmentsize/etc globals with a struct that
is now cached on the module data hung off the communicator. i.e. done right.
(c) On module init if dynamic rules enabled we call a general getvalues routine (in coll_tuned_forced.c) to get the
CURRENT values using the MCA param indices and then put them on the modules data segment.
A shorter version of getvalues exists for barrier which only needs the algorithm choice

- Some initial work on prepare_src
- Move some fragment initialization around
- Fix a union casting issue on picky compilers, identified by Don Kerr
- Other small cleanups/bugfixes

we send our local addr_t OOB. Remote side then matches endpoints and calls
dat_ep_connect(). Everything should be the same as before from here, except
that client/server roles are reversed.
- Properly set our buffer size when posting receives. When the frag used to
transfer address information is recycled by the free list, the wrong buffer
size was being used, which caused buffer overflow errors.
- Finally put the uDAPL error handling stuff in the mpool component.
- Remove a few more OPAL_OUTPUTs.

We support all the events in the PERUSE specifications, but right now only one event
of each type can be attached to a communicator. This will be worked out in the future.
The events were places in such a way, that we will be able to measure the overhead
for our threading implementation (the cost of the synchronization objects).
This commit was SVN r9500.
Not much got tested that wasn't already - I've uncovered a connection
establishment deadlock and wanted to get these changes committed before I
attack it.
The big changes:
- Moved much of the connection code from btl_udapl_component.c to
btl_udapl_endpoint.c.
- Cleaned up initialization of various fragment members.
- MCA_BTL_UDAPL_ERROR macro, which is compiled in/out appropriately.
