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...

add more comments for the migration tool.

back out "resource temporarily unavailalbe" entry, since we've taken a

add an entry about sysv shared memory and EAGAIN.  not sure if anybody else
will run into this but if they do and they google for the error message
hopefully they'll get this

add an anchor for slocate faq

add an item about disabling daily indexing

Patch disables sendfile system call support by default from PVFS2 since it has negative fallouts
on NFSD performance.
However, this also means Apache would not work off PVFS2 unless an EnableSendfile option
is turned off for Apache.
However users are still given a configure time option to --enable-kernel-sendfile
if they don't plan on re-exporting PVFS2 through NFS.
Updated FAQ to reflect this change.

add an item about write slowdowns triggered by bugs in ext3 reservation code

fix compile error and merge from trunk

label a few more sections

Added a sendfile callback to the pvfs2 file_operations structure so that Apache
can work off PVFS2 volumes.
This callback does not make use of the page-cache to avoid any of the associated
consistency problems.

add the entry about 'mmgrab' and 'flush_icache_range'

Just when we get a handle on Fedora, SLES 9 shows up...

) not }

This patch adds a new system interface (listeattr) to list the extended attributes

Also adds support in the VFS kernel module to support the listxattr
system call and a bunch of test programs to debug these.

Updated the FAQ to reflect usage of xattrs through VFS and acls through
VFS.
