r24976 wasn't quite right -- you now actually get a warning if you
specify btl_tcp_if_include because btl_tcp_if_exclude is defaulted to
the loopback devices.

This commit does a few things:

 * Introduce a new OPAL MCA base function:
   mca_base_param_check_exclusive_string().  It checks to see that the
   ''user'' does not set two MCA parameters that are mutually
   exclusive by checking the source of those MCS param values.
 * Use the above function in many BTLs (and the OOB TCP) to ensure
   that <foo>_if_include and <foo>_if_exclude are not both specified
   ''by the user''.
 * Re-arrange many of these BTLs to move their MCA registration code
   into a separate component_register() function (vs. the
   component_open() function).

This code has been nominally reviewed and checked by Ralph, George,
Terry, and Shiqing.
