[svn-r15676] Description:

	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 10.5.4 (amazon) in debug mode
        Mac OS X/32 10.5.4 (amazon) w/C++ & FORTRAN, w/threadsafe,
                                in production mode
        FreeBSD/32 6.3 (duty) in debug mode
        FreeBSD/64 6.3 (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/Intel compilers w/default API=1.6.x,
                                w/C++ & FORTRAN, in production mode
        Solaris/32 2.10 (linew) w/deprecated symbols disabled, w/C++ & FORTRAN,
                                w/szip filter, in production mode
        Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN,
                                in production mode
        Linux/64-ia64 2.4 (tg-login3) w/parallel, w/FORTRAN, in production mode
