[svn-r12990] Description:

    When using the latest version of the file format, move the "modification
time" information into the object header prefix, which is more efficient.
Also add "access time" and "change time" (for metadata) fields, all of which
take about the same space as the previous modification time header message.

Tested on:
    Linux/32 2.6 (chicago)
    Linux/64 2.6 (chicago2)
