Andrew Friedley ec995160e6 Checkpoint for switch to mpool work:
- Remove printing of CFLAGS in configure.m4
 - Set MCA_BTL_FLAGS_SEND flag
 - Improved error handling during module initialization
 - Extract the address of each interface with dat_ia_query
 - Start playing around with fragment stuff - probably wrong
 - Misc code cleanup (removal of GM-specific code)
