Get Fortran executable arguments

We usually work with Fortran programs and it is always useful to have the arguments of the executable in the Darshan log. This feature allows Drshan to get the executable name and the arguments from /proc/self/cmdline if the program is Fortran (argc==0)

The MAP_OR_FAIL macro is resolving fopen rather than fopen64,
causing a NULL function pointer to be executed in the wrapper
in the case of using Darshan's LD_PRELOAD mechanism.

darshan-logutils now returns an error when encountering a log file
with a module version number greater than what the library was
built with. all utilities were also updated to account for this
modification

bug reported by William Yoo

The stdio module stores names for the default streams (stdin,
stderr, stdout) in the following format: <STDERR>. The '<' and
'>' symbols require proper escape characters in order to be
properly interpretated by the darshan-job-summary (perl) script.
