[svn-r15677] Description:

    Bring r15676 back from trunk:

        Centralize all macros for declaring "magic numbers"/signatures for
    objects in the file into src/H5Fprivate.h, so it's easier to know what
    values have already been defined, etc.

Tested on:
    Mac OS X/32 10.5.5 (amazon)
    Too minor to require h5committest
