The overarching goal of this commit is to set the framework up for multiple
(simultaneous) file systems, as well as fix some small errors that I found recently
while compiling on my Mac machine.

This commit does a couple things:
(1) It changes the make system for auxFilesys to support multiple types of file
    systems. We now set variables in the makefiles, as opposed to choosing which
    makefiles to include.
(2) It fixes an error in which "EREOMTEIO" is not found in errno.h on Mac machines.
    This is fixed by simple ifdefs in the file.
(3) It fixes an error when compiling with clang. We would previously get "treating
    'c' input as 'c++' when in C++ mode, this behavior is deprecated". This is fixed
    by renaming the extensions of the files so that Clang will treat them as C++
    files (.c -> .cc)
(4) We remove the "none" directory in the "auxfilesys" directory. The stub file is
    now moved into "hdfs".
(5) We remove the superfluous library linkages (clang was complaining about this).

Changing license from 3-clause BSD to Apache

As discussed over much time within Cray and on the Chapel mailing
lists, we are moving to the Apache License (and, in a separate
commit, contributor agreements) in order to move away from our
previous homegrown contributor agreements while getting a similar
level of protection from a standard form.  Hopefully this will
make the lawyers of the world happy without making any users sad.

Ask devs to email chapel_admin with clas and commit access requests.

Instead of mailing chapel-developers@, we are now asking people to send admin
