merge with Orange-Branch

Committed Windows client code to Orange-Branch.

Porting flow etc.

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

merging Orange Branch changes in

initial merge with Orange-Branch. much will be broken

merge of B2O-Blue-Sync,HEAD,and latest of Orange.

commiting changes from merge of Orange and Blue into test branch.

merged Bart Taylor's mtime versioning bug fix from trunk to 2-8 branch

patch from Bart Taylor to fix bug in mtime versioning on server

Updates and Fixes.

merged in changes from summer at LANL

reverse merge of direct IO changes to he-branch.

merge of direct IO code to PVFS HEAD.

Reverse merged and ported to HEAD.

changes to trove layer to add direct I/O funcionality (O_DIRECT).

Merge HEAD changes to TAS-branch.

walt3 reverse merge from head includes merges of pw's sm changes (no state declarations), cleanup of state machine code, and other general merging/fixes.

Update migration branch to current CVS version

Synchronization with HEAD

merge pw's fixes from HEAD that quiet warnings in non pthread scenario and include some headers that get missed otherwise.  Also fix some warnings that crept in.

include some headers explicitly that are pulled by pthread only in the posix locking case

Merge HEAD into Walt's branch.
Rework new state machines to the new cleanups introduced by Walt.

reverse merge from trunk.  working for now.

Reverse merge changes from HEAD to posix-extensions-branch.

Patch fixes the atime, mtime and ctime problems that people have
reported with PVFS2.
Patch changes the notion of who sets these times. Earlier behavior was the
clients providing the times to the server. New behavior is to have the
server set these times except in  the implementation of utimes() system
call whereby clients explicitly set the time (atime and mtime).
NOTE: We dont allow the clients to dictate the ctime setting at all since
that is consistent with all file systems.
So what we have is:
read, readdir -> atime update required
write, truncate -> mtime update required
ctime is updated on every setattr implicitly on the server.

Since there is no need for parent_*time fields in the server request for chdirent,
crdirent and rmdirent, the next step is to remove those fields, fix the endecode
macros and bump up the major version of the protocol.

Patch also implements these times lazily by flushing them only at the time
of a close rather than after every read/write which could be pretty
expensive.

Reverse merge from trunk to lockd-branch...

reverse merge of branch

reverse merge of trunk to branch

* [Phil] removed db stat left over from keyval-per-db days
* [Phil] added stranded bstream checking
* [Phil] added comparison function for dspace db
* [Phil] added db cache size and type config options

* [Julian] added tcp send/recv buffer size options

get branch to build

Added a few more missing files and fixes from HEAD to lockd-branch.
lockd-branch should build cleanly now.

commit of murali's 64bit fixes.

updates to my event changes to bring them inline with trunk

merge changes from trunk since branch point into branch.  Effectively moves the branchpoint to the latest trunk.

added extended attribute support

updates for adding extended attributes

another phil fix: it is an error to zero out the dfile count and dist_size in
this macro

- added a PVFS_util method to get the current system and return it as
  a valid PVFS_time type
- added arguments to the crdirent/chdirent/rmdirent operations that
  now can take optional parent atime/mtime/ctime fields
- added support on server *dirent operations that update the parent
  time attributes (if specified) on successful completion of the
  *dirent operation; null/zero time fields are not updated
- modified sys-create/sys-mkdir/sys-symlink/sys-rename/sys-remove to
  work with the new operations properly; in general,
  create/remove/rename operations updates the mtime and ctime of the
  parent directory, which is now properly supported
- moved some common server side attribute handling code into a macro
  to make it re-useable across several server state machines
- updated en{de}coding of modified operations
- misc cleanups

- applied Nathan's expandtab patch (expandtab-2.patch.gz)

  first referenced at:
  http://www.beowulf-underground.org/pipermail/pvfs2-developers/2004-July/000745.html

- a comment update and minor cleanups

- previous definition apparently breaks C99 strict aliasing rules

see http://lists.freebsd.org/pipermail/freebsd-current/2003-July/007559.html
for some detail if you're interested

- metadata storage overhaul (remove the METADATA_KEY from Trove_Common_Keys,
meaning that metadata is now properly stored in the dspace generic attributes
rather than as a separate key/val pair)
- clean up the 'find' test program to handle more than a fixed number of
  dirent entries
- misc other cleanups
- ChangeLog update

move the PVFS_handle_extent[array] type to pvfs2-types.h.in;  this better
separates the server-config from trove when being compiled on the client side.
(removes the trove.h dependency)

added a new PVFS_statfs structure (incomplete- just a few fields to
start with), implemented trove_collection_getinfo() to retrieve this
information from file system, hooked into server statfs implementation.
completely untested, and no client side support yet

header shuffling- you probably have to do a distclean to build after
updating
