[ofa-general] [PATCH 0/5] trap 144, node descriptor change handling.

[Ira Weiny]

I have altered these patches based on input from Hal.  There are now 5 of them.

   1) Enhance set_nodedesc.sh
   2) Add optional ibsendtrap test tool and create --enable-test-utils
      configure option
   3) Add mcm_rereg_test to optional test tool config option
      (This also updates the tool to use the new ibmad_gid_t since it would not
      compile otherwise.)
   4) Update OpenSM to respond to node description change flag
   5) Create osm_node_desc.h and move extern declarations into this common
      header.

This includes Hal's minor stylistic fixes as well as makes ibsendtrap an
optional testing util, rather than a default diag.

Thanks,
Ira
