[svn-r8158] Purpose:

    Code cleanup/optimization

Description:
    Query property list values once, at the beginning of the I/O routines,
instead of querying the property list values multiple (lots!) of times in
lower level routines.

Solution:
    Create "property list caches" for internal library queries of the property
list values.

Platforms tested:
    IBM p690 (copper) w/parallel & fphdf5
    h5committest
