[PVFS2-CVS] commit by pcarns in pvfs2/src/common/misc: pvfs2-util.c

[CVS commit program]

Update of /projects/cvsroot/pvfs2/src/common/misc
In directory parlweb:/tmp/cvs-serv5270/src/common/misc

Modified Files:
	pvfs2-util.c 
Log Message:
added hooks to add file systems _after_ system interface initialization, 
updated apps accordingly, made pvfs2-ping more verbose using the extra info
that we now have access to.  still not very robust.  here are some
(temporary) limitations:
- client must initialize all compiled in flowprotocols and bmi modules from
  the beginning, no hooks to init them as we go
- can't remove file systems that have been added
- probably can't yet add file systems that didn't come from parse_fstab() call
