Merged robust security code into Orange-Branch.

changes to PVFS_handle_X

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

encoding fixes

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.

Timing measurments

storing parent de implementation

merged in changes from summer at LANL

Initial commit of parallel fsck code

Merge range query changes and other fixes

patches from Dries Kimpe:
- Added check before redefining USE_GNU in pvfs2-server.c
- Made use of endecode_fields_xxx macro's consistent and solved warning
in case they were compiled out.  The macro should be used as a function
call, and thus have a semicolumn at the end.

merging hints/events code into trunk.

Updated encoding.

Reverse merged and ported to HEAD.

Bugfix two for the morning.

Merge from HEAD.  Fleshed out credential.  Encode/decode added for credential and cleaned up for capability.  Added capability/credential into request/response structures.  Fleshed out comments in security module.

Added encoding/decoding functions for the PVFS_capability structure.

hints and events.

Zero out pad bytes after distribution.  Fix bug where an aligned distribution would always send an extra 8 bytes.  This requires a protocol version bump.

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

need 6-field encoding

Modification for migration added, some functions still need to be adapted after moving to a new branch...

Migration of datafiles between different servers works. Uses msgpairray.sm,
transfers only one datafile between two servers and rewrites metadata.
Todo: Adaption of request scheduler to ensure that migration and write
I/O do not happen concurrently on source dataserver.
Also allow users to specify command line parameter which supresses
transfer of pvfs2-hints.

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

merge of murali's changes from trunk.

[pcarns]: Patch to allow modifying distribution, distribution parameters and number of
data files to use within a given directory. Such setting will only impact creation of future files
within the same directory. It does not change existing files' parameters. All such hints
are inherited by newly created directories as well..
[pcarns]: Allow trove to continue to read a list of xattrs/keyvals
without stopping if some subset of keys dont exist in the keyval db. Modifies the keyval_read_list() function
to return an array of completely independant error codes for each key that is read.
[pcarns]: adjust encode_string() macro to make it safe to call on NULL strings
[pcarns]: bug in the getattr state machine that would cause it to read dirent_count most of the time
regardless of whether the attribute mask requested it or not.
[slang]: fix a couple of bugs in the get-attr server-side state machine whereby the dirent_count was being read
using the dirent handle instead of the dirdata handle. Fixed a return value from dbpf_keyval_get_handle_info_op_svc
so that get-attr would not needlessly hang..
[vilayann]: fixes for the viewdist utility yet again, since the keys for the xattrs have changed...

First cut of the sys_readdirplus implementation where clients can issue a single
system interface call to get the directory entries as well as the attribute information
of the directory entries.
What this means is that we do not need to call a sys_getattr of the individual directory entries
anymore.
(The kernel version is still untested and won't work until the VFS patch is in place! :))

On the server, there is now a new request/state machine called listattr(poor name, i know!)
which essentially does a vectored getattr for a list of handles as opposed to a getattr
which only does for 1. Perhaps, we need to consolidate them into 1 at a later point of time after
others have given this code a look-see!
On the client, there is a new system interface, and a corresponding statemachine implementation
called readdirplus which does the following algorithm
a) Step 1 - Do a regular readdir
b) Step 2 - Collate all meta handles (obtained from the readdir) and send out 1 listattr
to every server that owns atleast 1 handle from the set.
c) Step 3 - Handles that refer to metafiles (determined by the attributes of the response)
need an additional step to retrieve their file sizes. So we collate all data file handles
of all metafiles, and send out 1 listattr to every server that owns atleast 1 handle from
the set.
d) Step 4 - Copy object attributes obtained for all objects into the sys response structure and
also compute file sizes of regular files since we know the individual dfile handles' file sizes
from Step 3.

Clearly, this is a huge win in terms of performance of listing directories which have large number of directory
entries.
Next step is to hammer out the VFS patches and coreutils patch for ls to get the same benefit.
Also added a new utility called pvfs2-lsplus in src/apps/admin that uses this API.

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

commit of versioning stuff to branch

ib: encode data structures to support heterogenous architectures

changes from head merge

changes to perfbase benchmarks and addition of perf counter queue fields

merging changes from HEAD to dbpf branch

align geteattr req, small_io resp; small_io req alignment to be fixed by Murali with his patch

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.

Murali's patch to add VFS support for extended attributes.

added extended attribute support

updates for adding extended attributes

* added event logging for states
* moved state debug code to state-machine so all state start/end
points get debug messages automatically
* added textlog stuff.  This allows us to write the default event
queue out to a text file that can be converted to slog2 later.

significant protocol changes to solve 64-bit alignedness issues

align 8-byte alignment primitive

- fixed test program ls.c and admin program pvfs2-ls.c to not issue
  an extra call to readdir on every run by fixing a slight logic bug
- changed some readdir debugging
- added a directory version that is passed back from the server to
  the client on each successful readdir call (happens to be the
  directory's mtime encoded as an opaque uint64_t)
- updated client and server response structures and encoder to
  accomodate this
- NOTE: the versioning is not perfect since retrieving the directory
  mtime and iterating the handle list isn't an atomic operation with
  respect to the overall readdir op; i.e. there's still a window where
  a difference may not be detected.  then again, since the mtime is in
  seconds granularity, this should not present a major detectable
  problem anyway.  can use a different version number if problems
  arise often in practice

make statfs return load averages from sysinfo()

- add configure test for sys/sysinfo.h (should be on all linux machines)
- add memory and uptime information into the (now ill-named) statfs object
- update pvfs2-statfs to display this newly added information

add just encoding stubs in system install dir
