(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
