Jeff Squyres 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
