vchoi_fork

[svn-r11903] Purpose:

Add files that I forgot in my last checkin.

Description:

cache_api.c cache_common.c cache_common.h are new files that result
from breaking the old cache test into two tests.


Solution:

See above.

Platforms tested:

h5committested before the last checkin.  Will run another
h5committest shortly, but it shouldn't be necessary as there
are no new changes.

Misc. update:
