This commit fixes some bugs uncovered during thread testing of
2.0.1rc1. With these fixes the component is running cleanly with
threads.

Split the CMA test into two parts so that the back-end test only has
to be run once. Fail with --with-cma is specified and cannot be
provided. Remove a few useless quotes. Change
$ompi_check_cma_need_defs and $ompi_check_cma_happy to be numeric
values. Finally, remove a bunch of tabs.

Each process occupies a "slot". We automatically set #slots = #cpus if nothing else is told to us. If you want to run more procs and slots, you must tell us to allow oversubscription.
A process can utilize multiple pe's if that option is given. If you try to bind more than one proc to a given pe, then we will error out unless you tell us to allow overloading.
Adding a mutex to thje ompi_file_t structure allows to have a per-file handle
mutex lock for both ROMIO and OMPIO. I double checked that the size of the
ompi_file_t structure is still below the size of the predefined_file_t structure,
so we should be good from the backward compatibility perspective.
Also, remove the lock/unlock in the file_open ompi-interface routines of romio314.
The global lock in the romio component does probably not work, it is easy to construct a testcase where two threads perform collective I/O operations on different file handles. With a global lock it is easy to deadlock. THe lock has to be at least on the file handle basis.
move the mutex to file/file.c to avoid duplicate symbol problem in file_open.c pfile_open.c
This commit should restore the pre-non-blocking behavior of the CID
allocator when threads are used. There are two primary changes: 1)
do not hold the cid allocator lock past the end of a request callback,
and 2) if a lower id communicator is detected during CID allocation
back off and let the lower id communicator finish before continuing.

In conjunction with a de-duplicating .mailmap file, use the
make-authors.pl script to auto-generate AUTHORS.

Update the script to auto-generate the entire AUTHORS file from two
sources:
1. The existing AUTHORS file
2. The output from "git log --format=tformat:=tformat:'%aN <%aE>'"
Merge these two together (which will preserve organization
affiliations) and warn in two cases:
1. If a person has no organization affiliation
1. If the same email address appears for more than one person
