Merged robust security code into Orange-Branch.

added new uid management app under src/apps/admin/pvfs2-get-uid
also included are a server and client side sm and the uid mgmt implementation files

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

change to #defined calls to uuids

migrate from uint64_t type assignments to uuids

distributed directory structure for root and lost+found directory. In pvfs2-server.c, it will check if the root directory is set. Need 10~20 seconds for creation when the servers are launched at first time.

redesigned lookup code to work with security

Fixes to lookup.

Next round of distributed directory changes.

*** empty log message ***

initial merge with Orange-Branch. much will be broken

cleaned up credential verification

removed anything and everything related to certificates

revert cu-security-branch to before the attempted merge with Orange-Branch

Merge branches

merged in changes from latest Orange-Branch

*** empty log message ***

merged in changes from summer at LANL

initial get-path state machine and associated changes

Initial commit of parallel fsck code

Initial import of branch supporting keyval attribute/value lookup

fixed invalid free() in io.sm.

Revised the allreduce.sm and other related codes accordingly.

*** empty log message ***

Added the server to server communication module within pipeline.sm
to pull the small portion of data when the data is not aligned on strip boundaries.

Changed the default file stripe size to 256KB (originally 64KB)
so that pipeline unit is equal to it.

Setting up Orange Branch

new server state machine to handle getcred requests

merging hints/events code into trunk.

tree communication implementation

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.

db-replication state machine which processes the incomming replication message

Pass the fs_id with the replication message

db-rep-send state machine added

Added lock op.

Reverse merged and ported to HEAD.

modified permission checking to use callbacks instead of flags. added custom
checks to the io and small-io state machines.

hints and events.

syncing small-file-branch back up with trunk at small-file-branch-point2 tag
(reverse merge)

sorting out some request types

set up for create-file mod - stubbed out stuff, etc.
a few small bug fixes to statecomp and statemachine stuff

couple more.

readonly symbolic

Change access_type functions from 0/1 to use the enum
PINT_server_req_access_type.  There may have been some backward
conditionals in here.  This at least makes them all visible,
and fixes a problem with ReadOnly exports where only reads
(but not writes) were forbidden.

Sam's prelude and scheduler updates

fixes for building request unify commit.

The normal path for a server request operation is to jump to the prelude state machine, which tries schedule the request based on the handle+fsid.  This meant that the request scheduler code had a switch/case returning the handle+fsid for each request we defined.  The function was also overloaded with a readonly parameter (whether the request modified any objects on the server), and a scheduling policy parameter (as the return code), which specified whether the request scheduling could be bypassed for this request.

I moved all that to a per-request parameter structure, that gets specified within the server state machine for the request.  Now there is one array of server requests (moved to pvfs2-server-req.c) which the request scheduler and prelude state machine can poke at to get parameters (defined in the state machine for that request), and based decisions on.

The patch includes some other minor changes:

* A fix to the BMI addr ref count increment/decrement.  Previously, the addr ref count was being incremented/decremented in the prelude/final-response state machines.  That requires that those state machines get invoked, which I don't want to have to depend on.  I've moved the INC call to the unexpected_sm, and the DEC call to where the state machine gets finished in the server.  That way we don't have to worry about whether we're using prelude/final-response.

* Cleanup of the request scheduler.  The way we were changing the mode from normal to admin was sort of embedded into the request scheduling code, so we had to hack the mode change from prelude_sm instead of in setparam.  Also, the request scheduler had to be aware of the setparam fields in the request.  I've moved the mode change code to separate request scheduler and job calls.  I think something similar could be done for the timer code (it doesn't really belong in the request scheduler), but I'll leave that for another patch.

* Changed the way we compile the server binary in Makefile.in to allow for multiple object files.
