[svn-r6411] Purpose:

    Code cleanup

Description:
    Clean up miscellaneous warnings which have crept into the code.

    Fix "_POSIX_C_SOURCE not defined" warning on FreeBSD.

    Adjust gcc compiler flags to be more concise for production mode.

    Refactor the H5O code so that there is a stronger boundary between code
    in the H5O package and code in the library which just calls H5O routines.

Platforms tested:
    Tested h5committest {arabica (fortran), eirene (fortran, C++)
	modi4 (parallel, fortran)}
    FreeBSD 4.7 (sleipnir) serial & parallel and gcc 2.95.4 & gcc 3.2.2

Misc. update:
    Update MANIFEST if you add or remove any file.
