* unify handling of env variables
create a class containing all (most?) environment variables used by rocshmem and an object that is instatiated
before library_init, since some of the environment variables need to be
set before we start the bootstraping process.
This allows us to remove two files from the bootstrap directory.
* replace INFO and TRACE macros with DPRINTF
to be more consistent with the rest of the rocSHMEM code
