[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
