LU-1842 quota: define quota records for glb/slv indexes

This patch defines lquota_glb_rec & lquota_slv_rec which are the
record which will be used with the global & slave index files.
It also introduces the global quota lu_context_key which will be used
by all quota-level handlers.
The lquota module init/exit function are now defined in lquota_lib.c
which calls the old quota init/exit function for the time being.
Finally, this patch also modifies lquotactl_slv() to collect
enforcement information.

LU-1512 oi: reuse idle OI blocks

With the system running, some OI blocks may become empty because
related files have been removed. Originally, these empty blocks
almost cannot be reused beause it always allocates new block for
new leaf or index node. Such space waste is an important reason
for the OI file size increasing quickly.

Now, when the non-released OI leaf node becomes empty, it will be
recycled into a per-OI based idle blocks pool, which is organized
as a series of tables. For each table, the on-disk format is:

+---------+---------+---------+---------+------+---------+-------+
|  magic  |  count  |  next   |  logic  |      |  logic  | free  |
|(16 bits)|(16 bits)|  table  |  blk #  | .... |  blk #  | space |
|         |         |(32 bits)|(32 bits)|      |(32 bits)|       |
+---------+---------+---------+---------+------+---------+-------+

The logic blk# for the first table is stored as "idle_blocks" in
the OI root node. In fact, there is padding field in the OI root
node after the "dx_countlimit". We will append the "idle_blocks"
just after the "dx_countlimit" to reuse part of the padding. So
it will not cause compatibility issues with old OI files.

Adjust the strategy for OI file block allocation: reuse empty block
in its idle blocks pool with priority; if such pool is empty, then
allocate new block from system volume.

LU-1644 mgs: swab nidtbl entries for 2.2 clients

LU-1252 is missed in 2.2 release so it caused a problem that 2.2
clients always swab nidtbl entries even if the server and client
are using the same endian.  Conversely, 2.3 clients would not
swab the nidtbl entries but the 2.2 server would always swab.

To make it work, 2.3 adds a temporary OBD_CONNECT_MNE_SWAB flag,
which will cause the server to swab the nidtbl entries for 2.2
clients, and 2.3 clients will undo the swab done by 2.2 servers
if the MNE_SWAB flag is not set.  This avoids problems with only
checking the client/server version, in case the LU-1252 fix is
ever applied to a 2.2 client or server build.

This workaround is set to auto-expire for 2.5.50+ clients and
servers, which is a reasonable upper limit for interoperability
with old unpatched 2.2 clients in a mixed-endian environment.
This is enough for 2.2.0 clients/servers to work with the 2.5.x
feature releases, after which the OBD_CONNECT flag can be reused.

LU-1629 ldlm: Fix recovery messages when denying new clients

Console messages printed when denying new client connections during
target recovery show misleading client statistics.  For example, in
this case:

  Lustre: lustre-MDT0000: Denying connection for new client
  192.168.117.50@o2ib1 (at 11e711ab-a329-f07a-8312-6a40af7fc5a4),
  waiting for 0 clients in recovery for 2:38
  [...]
  Lustre: lustre-MDT0000: Recovery over after 5:00, of 112 clients 0
  recovered and 112 were evicted.

The MDT was actually waiting for all the 112 known clients to recover.
None had connected, however.  In addition, the client NID and UUID
seem to be in the wrong order.  This patch changes the first console
message to look like this:

  Lustre: lustre-MDT0000: Denying connection for new client
  939243e4-2f54-a96f-3cbb-9fcf55426e2e (at 0@lo), waiting for all 2
  known clients (1 recovered, 0 in progress, and 1 unseen) to
  recover in 0:05

Hopefully this new format will be a little bit more useful to users,
although the counters are (still) read in a racy way.
