Made sure each .F and .h file had
the CVS keywords Header and Name at its start.
Most had header but very few currently have Name, so
lots of changes!

Added a byte swapping routine for the Linux platform so that
g77 compiled code can read/write big-endian data. This ought not
be a permanent feature of mdsio.F but it's not clear how to
better deal with this other than use little endian data.

Implemented new I/O package (mdsio.F). This package does parallel
I/O in much the same way as dfile.F used to except it uses "direct
access" rather than (f77) unformatted sequential access.
Problems with dfile.F package included:
o unnecessary memory use (each process had two global sized buffers)
o inability to read the files it had written without post-processing
o "tiled" files were tiled by process/thread rather than actual tiles
o created huge numbers of files with no alternatives
Features of the mdsio.F package:
o direct-access binary writes
o no excessive memory use
o ability to read/write from multiple record files
o "tiled" files are based on "WRAPPER" tiles so that the number
and content of files is independent of the number of threads
and/or processes
o option to create single "global" files rather than "tiled" files
o ability to read both "global" and "tiled" files
[Caveat: the tiling of files must match the model tiles]
o checkpoints now use a single file per model section
ie. one file for the hydrostatic model core, one file
for the non-hydrostatic extensions and one file for the C-D
extensions
o the mid-level I/O routines now is broken into more source files
read_write_fld.F supplies basic I/O routines with the same interface
as the original I/O package
read_write_rec.F supplies I/O routines which allow multiple records
write_state.F writes the model state
checkpoint.F supplies the read/write checkpoint routines
All the example input data has had to be modified to be direct-access.
Otherwise only routines that used I/O have been affected and not
all of those have been due to the continuity of arguments in
the read_write_fld.F routines.
What needs to be done? We have to create a suite of conversion
utilities for users with old-style data. Also supply the option
for using old-style I/O, not just for die-hards but for reading
data too extensive to be converted. And more...
