[svn-r14860] Description:

	Omnibus raw data I/O revisions, with wide-ranging changes and
refactoring, in order to prepare for implementing "fast append" feature.

	These changes remove the majority of the code duplication for raw data
I/O which has crept in over the last ten years and introduces a more object-
oriented design for operating on different types of dataset storage.

	Chunked storage no longer has it's own I/O routines, it is now handled
as either contiguous (if chunk is not pulled into the cache) or compact (if the
chunk is cached in memory).

	No bug or feature changes, at least intentionally... :-)

Tested on:
        FreeBSD/32 6.2 (duty) in debug mode
        FreeBSD/64 6.2 (liberty) w/C++ & FORTRAN, in debug mode
        Linux/32 2.6 (kagiso) w/PGI compilers, w/C++ & FORTRAN, w/threadsafe,
                                in debug mode
        Linux/64-amd64 2.6 (smirom) w/default API=1.6.x, w/C++ & FORTRAN,
                                in production mode
        Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN,
                                in production mode
        Solaris/32 2.10 (linew) w/deprecated symbols disabled, w/C++ & FORTRAN,
                                w/szip filter, in production mode
        Mac OS X/32 10.5.2 (amazon) in debug mode
        Linux/64-ia64 2.4 (tg-login3) w/parallel, w/FORTRAN, in production mode
