A few more notes:

3. Most of the files in orte/mca/rmaps/rankfile do not obey the prefix
rule. I think that they should be renamed.

4. A quick look through rankfile_lex.l seems to show that there are
global variables that are not protected by the prefix rule (or
static). Ditto in rmaps_rf.c. These should be fixed.

5. rank_file_done was instantiated in both rankfile_lex.l and
ramps_rf.c (causing a duplicate symbol linker error on OS X). I
removed it from rmaps_rf.c (it was declared "extern" in
rankfile_lex.h, assumedly to indicate that it is "owned" by the lex.l

6. svn:ignore was not set in the new rankfile directory.
