hdf5/test/unlink.c
Quincey Koziol 9d2070890b [svn-r13636] Description: 
Change H5[D|G|T]<foo>_expand() "temporary" API routines to
H5[D|G|T]<foo>2() "versioned" routines.  Also added
H5[D|G|T](create|commit)_anon() routines to continue to allow "anonymous"
objects to be created in a file.

Tested on:
    Mac OS X/32 10.4.9 (amazon)
    FreeBSD/32 6.2 (duty)
    FreeBSD/64 6.2 (liberty)
    Linux/32 2.6 (chicago)
    Linux/64 2.6 (chicago2)
