bdc527eba8 filestore: enforce min and max sync interval 
Ideally the min sync interval should be self-tuning (ala ext3, xfs),
but that can come later.

06e396139b kclient: only unregister after both acks 
Partially reverts behavior of b732c0ddb8

We need the request to stay in the request_tree so that when the
safe arrives we can look it up (duh).  Also, we need to keep a
reference to the request during that period...

b732c0ddb8 kclient: unregister mds requests on unsafe reply 
Fresh vs unsafe mds request replay is handled separately.  So,
unregister requests on first reply.  This avoids a stray dentry
reference if we unmount before getting a final safe (although
eventually those should be explicitly flushed as well).

376ac88a3b kclient: async mds requests 
Restructure the mds client to handle mds request asynchronously, so
that we can handle requests that are not managed by a blocking
thread.

0b75ee62d4 mds: use generic helper when removing a cap 
This way we make sure to do all the right checks on the locks,
mds_caps, and to call eval_stray if the inode is unlinked.

179f7a81e2 mds: fix try_remove_unlinked_dn 
Clear dentry NEW flag when we commit it.. pretty sure that was the
old bug.  And we can't cheat the directory commit because the fnode
also gets updated.

1c2d62486f mds: drop rdlocks _after_ journaling; use new journal_and_reply helper 
If we drop locks earlier we may run contexts that journal _other_

3eabcec0d4 mds: rewrite SimpleLock using generic state specifications; new xlock semantics 
Same client can re-xlock an item (or read_projected) if the prior
locker set_xlock_done().  Move from XLOCKDONE to either SYNC or
LOCK, depending on whether read leases/locks have been issued.

Still need to convert FileLock and ScatterLock to use the new
state machine specification.  (This will probably make those lock
types mostly go away.)

7bd95881a9 mds: force explicit current vs projected dentry linkage in API 
CDentry users must use get_linkage() or get_projected_linkage()
(or get_linkage(int client) to autochoose) to explicitly specify
whether they want the current or projected dentry linkage.

314f065d02 mds: simplify capability issued tracking 
The original was really stupid.. keeping track of every issued
value in a list and traversing it to calculate the effective
issued mask.

New version has a small, fixed array that is used only when bits
are revoked.
