Cleanup some bitrot from moving the db framework to opal and from the new mca param system
update-my-copyright.pl now works with Git

This script now takes command line options:
```
./update-my-copyright.pl [options]

--help | -h          This help message
--quiet | -q         Only output critical messages to stdout
--check-only         exit(111) if there are files with copyrights to edit
--search-name=NAME   Set search name to NAME
--formal-same=NAME   Set formal name to NAME
```

The `--check-only` and `--quiet` options are suitable for use in a git
pre-commit script to check for out of date copyright headers.

The gm BTL was removed in June of 2012; there's no need for
ompi_check_gm.m4 any more.
First cut at assigning some fine-grained "levels" to MCA parameters
for the SM and TCP BTLs, as well as the mca_btl_base_param_register()
function (which registers MCA params for all BTLs).

The guidelines in
https://svn.open-mpi.org/trac/ompi/wiki/MCAParamLevels were used to
pick these levels.
