Corrected and clarified the purpose of the PLFSRC keywords.
In the prep patches, we do need to be patching for the O_RDWR behavior.

It turns out that turning off data-sieving works, but doesn't prevent
romio from opening a file read-write when calling on ADIOI_GEN_OpenColl.
We still need to patch, but we only need to patch the file that has
ADIOI_GEN_OpenColl, which is ad_opencoll.c.
Merge pull request #126 from dshrader/master

Put patching of ad_opencoll.c back in to the relevant prep patches.

Updated version name to indicate we're working on PLFS 2.3.
fix for container_rename() issue reported by David Shrader.
in the case where we need to transferCanonical() because the
canonical container moved, you have to update the filename
(because you've already moved the directories).    The code
computed the new name (in "old_canonical"), but it didn't
get plugged into the old plfs_pathback ("opb") because that
had its own (now stale) copy, so I added a line to update that
too.   (they are all C++ strings...).

also cleaned up some comments and fixed an unreleated problem
with backend handling (that would only have popped up on non-posix
backends).

rename fix
bug fix: print_backends() was only calling plfs_check_dir() on one
backend after the IOStore merge, as the check call was accidently
migrated out of the for loop.   Push it back in.  reported by
Aaron Torres et al.

Also new feature: have plfs_check_dir create nested dirs
(using mkdir_dash_p() function).

plfs_check_config fixes
Put Cray-specific directives around weak symbols.

With directives around the weak symbols, they are turned off by default.
Normal linking needs to be done when building MPI and leaving out the
weak symbols when dynamically linking will ensure that the right
versions of the functions are found.
Merge pull request #134 from dshrader/master

C directives around weak symbols so that only Cray uses them.
Add special instructions on patching Open MPI 1.6.x.
Merge pull request #136 from dshrader/master

Update patching documentation to include special instructions for working with Open MPI 1.6.x.
first stab at README.git
Added some mac crap to .gitignore and adding documentation for git
tweaks to documentation
Removed deprecated documentation for svn
Merge pull request #137 from agtorre/master

Changes to .gitignore and README's
Update README.developer with current processes.

We have gone to git, so many of the processes need to be updated to
reflect that change. We are also codifying, so to speak, the development
cycle and release process a bit more formally.
Update release process to allow committing directly to upstream.
