0af7ac53f2 Fixes trac:1392, #1400 
* add "register" function to mca_base_component_t
   * converted coll:basic and paffinity:linux and paffinity:solaris to
     use this function
   * we'll convert the rest over time (I'll file a ticket once all
     this is committed)
 * add 32 bytes of "reserved" space to the end of mca_base_component_t
   and mca_base_component_data_2_0_0_t to make future upgrades
   [slightly] easier
   * new mca_base_component_t size: 196 bytes
   * new mca_base_component_data_2_0_0_t size: 36 bytes
 * MCA base version bumped to v2.0
   * '''We now refuse to load components that are not MCA v2.0.x'''
 * all MCA frameworks versions bumped to v2.0
 * be a little more explicit about version numbers in the MCA base
   * add big comment in mca.h about versioning philosophy

b9520e61dc get the sm optimized allreduce working for all but user defined 
operations.  Added to the reduction operations a set of reduction
functions that take 2 input buffers and one output buffer to avoid
some extra memory copies.  These can't be used with user defined
operations.  The intel c collective suite passes both original, and
new (new, not the user defined operations).

afcd1016fd move temp buffer allocation out of the iteration loop - i.e. always use the 
same temp loop.  The algorithm is rather synchronous already...

0f9d642d51 temp buffer pointers are computed when they are set up. A bit more 
efficient, but more important, it is much easier to play around with
memory layout now.
