Merged robust security code into Orange-Branch.

remove extents, handle ranges, precreate pools and various other things that aren't needed in their current forms with UUIDs

changes to PVFS_handle_X

Merged in changes from Orange-Branch. There were a number of bugs fixed there since this branch was created.

merge with Orange-Branch

Next round of distributed directory changes.

update to multiple pre-create pool implementation, only create pools for servers of the types they have to give (no I/O handles from meta only servers)

*** empty log message ***

per-dataspace handle type precreate pools implementation

merged in changes from summer at LANL

merging hints/events code into trunk.

reverse merge from HEAD.

reverse merge of changes to HEAD since branch.  Includes small file changes.

Merging small files branch to head.  Includes server side precreation of
data files and file stuffing.

reverse merge latest trunk changes to small-file-branch and update msgpair
usage where needed

added a mechanism for pool fillers to signal the job interface when they
think that they will not be able make progress soon.  This prevents callers
waiting on handles from hanging indefinitely.

some server side error handling cleanups.  If refiller fails, sleep for a
bit and try again later rather than giving up entirely.  On startup mainly
just log errors and shutdown gracefully; those are crticial
misconfiguration problems.

Big pile-o' changes to make Pete go mad.

The main changes are the implementation of the stuffed create path (now just the create state machine and operation), and the beginnings of the "unstuff" operation.

This also includes the request scheduler and state machine cleanups (required for using prelude with batch_remove) and whatever else I may have happened to change along the way.

This code is able to create files, but writing to them is almost guaranteed to break.

config file control of some precreate parameters.  rather conservative
default parameters for now

function comments

add a flag so that servers can keep the msgpair code from error logging on
retries

fix retry values for servers so that they try forever to contact each other
when precreates are needed

first cut at function to block until precreate pool count gets low.  Mostly
works, except the pool count isn't being intialized properly

persistent storage of precreated handles, more tweaks to allow binary keys

Preliminary cut at servers asking each other for handles.  Request is
exchanged, but doesn't do anything yet.  Also some tweaks to how precreate
pool information is assembled at startup.

stubbed in state machine to handle refilling precreate pools

file precreate-pool-refiller.sm was initially added on branch small-file-branch.
