[svn-r27882] Added smoke check 5 and associated fixes.  Note that at present,
smoke check 5 create a ~15 GB test file -- need to reduce this.

Added api error tests and associated fixes.

Turned on the persistant free space manager in smoke checks.
This exposed major issues with the free space manager.  For the
time being, modified cache image to ommit file free space managers.
Also, related fixes and improved sanity checking code.

Tested serial and parallel on mercury.

Tested serial only on Jam -- parallel test failed in configuration
(mpicc didn't produce executable code).  As all works well on Mercury,
I presume this is caused by something getting updated out from under
me.
