Landing statfs cache code.
- preliminary for prealloc (bug 974)
- preliminary for QOS (bug 855)
- speeds up parallel df
- speeds up lprocfs
Lprocfs underwent a bunch of cleanup (mostly from Intel, partly from me)
to remove lots of macros and strangeness w.r.t. per-target statfs values.
Still open for discussion is how old the cached statfs values can be.
I arbitrarily picked 1 second for client statfs, lprocfs, and target
statfs caches. We may want to change that, or allow it to be tunable.
Note that this code is different than that in bug 855, in that the
max_age parameter is an absolute age in jiffies, whereas the patch
in bug 855 used a relative time in seconds. The thing I'm trying
to avoid is if we say "I want a result up to 1 second old", but we
get delayed during an RPC and we don't know what "1 second old" is
related to.

Fix problems with new write_record() interface:
- we were not incrementing the size properly
- block > i_size >> blkbits was never true when it needed to be
- new size was always 1 block too small
- when size was set, it didn't make it to disk, because
ext3_get_block_handle() updated size after marking the inode dirty
Proper fix is to move i_disksize update into ext3_splice_branch(), so that
it is done before inode is marked dirty. For now, we mark inode dirty
again in fsfilt, so we don't need a new kernel for Wed LLNL debug shot.
Make fsfilt_ext3 and fsfilt_extN identical again (cosmetic changes only).

* bug fixes
- Fix ldlm_lock_match on the MDS to avoid matching remote locks (592)
- Fix fsfilt_extN_readpage() to read a full page of directory
entries, or fake the remainder if PAGE_SIZE != blocksize (500)
- Avoid extra mdc_getattr() in ll_intent_lock when possible (534, 604)
- Fix imbalanced LOV object allocation and out-of-bound access (469)
- Most intent operations were removed, in favour of a new RPC mode
that does a single RPC to the server and bypasses most of the VFS
- All LDLM resource ID arrays were removed in favour of ldlm_res_id
- Aggressively cancel local locks on DLM servers
- mds_reint_unlink sends EA to the client if it's the last nlink.
client uses that EA to unlink OST objects.
- mds_reint_{rename,unlink,link} were rewritten to take ordered locks
- recursive symlinks were fixed (440)
- fixed NULL deref in DEBUG_REQ
- filter_update_lastobjid no longer calls sync, which annoyed extN
- fixed multi-client small-writes to a single file problem (445)
- fixed mtime updates during file writes (607)
- fixed vector writes on obdfilter causing problems when ENOSPC (670)
- fixed bug in obd_brw_read/write() (under guise of testing 367)
- fixed Linux OST size reporting problem (444, 656)
- OST now updates object mtime with writes or setattr (607, 619)
- client verifies file size before zeroing page past EOF (445)
- OST now writes last allocated objid to disk with allocation (108)
- LOV on echo now works (409)
* protocol changes
- mds_reint_unlink sends a new buffer, with the EA included. this
buffer is only valid if body->valid & OBD_MD_FLEASIZE, which is only
set if a regular file was being unlinked, and it was the last link
- use PtlGet from the target for bulk writes (315)
- OST now updates object mtime with writes or setattr (607, 619)
- LDLM now has a grant-time callback to revalidate locked items, if
necessary (604)
- Many MDS operations were reorganized to combat race conditions
* other changes
- Merge b_intel branch (updated lprocfs code) - now at /proc/fs/lustre
- configure check to avoid gcc version 2.96
