[svn-r18415] Description:

    Move the libhdf5.settings information out of src/H5Tinit.c and into a
separate header file (src/H5lib_settings.h), which is generated at build time
(not configure time) with the src/H5make_libsettings generator program.

Tested on:
    Linux/32 2.6 (jam)
    Mac OS X/32 10.6.2 (amazon)
