[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
