[svn-r12656] Description:

    Add "use the latest version of the file format" flag to the file access
property list and internal file data structures.

    Fix bug where metadata block size was retrieved instead of the small
data block size.

    Categorize property list routine prototypes in the public header file.

Tested on:
    Mac OS/PPC 10.4 (amazon)
    Linux/32 2.6 (chicago)
    Linux/64 2.6 (chicago2)
