Loading osd_zfs.ko at this point, which is necessary under certain
debugging/testing circumstances, will get ENFILE from
lu_context_key_register().  To make developing on single-node setups
easier while minimizing new array iterating overhead, this patch
increases the size of lu_keys[] by eight words.

A couple of additional things were considered too.  First, the number
of keys may be reducible.  For instance, the md_ucred and md_capainfo
keys in mdd might be merged into the mdd_thread_info key, at a quick
glance.  However, the amount of change is not small.  The other thing
is that lu_keys[] could be dynamically allocated and grown on demand.
But additional locking is required when synchronizing
lu_context::lc_value[]s with lu_keys[].

LU-2258 mount: solve races between evict and umount

There are two race conditions between evict and umount.

1) The one is that obd_export_evict_by_xxx() can touch a lustre hash
which has already been finalized but not unregistered yet.

2) The other is that the class_decref() in lprocfs_wr_evict_client()
can call lprocfs_remove() via osc_cleanup() while having _lprocfs_lock
already. That's why this case ends up in a deadlock.

This patch solve these problems with the below solutions.
- see if obd_nid_hash and obd_uuid_hash is still available when
  evicting.
- move class_incref() to below LPROCFS_EXIT() and class_decref()
  before LPROCFS_ENTRY() in order to avoid dead-locking

LU-2285 osp: Fix last_created updates after orphan cleanups

After an OST orphan cleanup, the OST's last created ID plus one is
stored into opd_pre_last_created.  This is weird and contradicts with
osp_precreate_send() and a few other places, like the following except
from osp_precreate_reserve():

  ...
  precreated = d->opd_pre_last_created - d->opd_pre_used_id;
  if (precreated > d->opd_pre_reserved) {
          d->opd_pre_reserved++;
  ...

The issue is not only about coding style, as suggested by this piece
of debug log dumped by a run of replay-ost-single 2:

  00000004:00080000:0.0:1353838616.328831:0:14474:0:(osp_precreate.c:4

  42:osp_precreate_reserve()) lustre-OST0000-osc-MDT0000: precreated 1

  01:osp_precreate_get_id()) lustre-OST0000-osc-MDT0000: Incremented o
  pd_pre_used_id: 131

The first line says that opd_pre_last_created was 131, while on the OST
side the last created ID was 130.  Then, according to the second line, a
request tried to reserve an object and found one.  The last line tells
us that the request consumed 131.  Actually, the OSP at that time hadn't
officially created 131 on the OST yet.

This patch makes sure opd_pre_last_created stores what its name
implies.

LU-2251 osp: remove invalid assertion

Given we initiate precreation before current pool is exhausted,
we can easly get final number of precreated objects more than
OST_MAX_PRECREATE but it should always be less then the
theortical max of OST_MAX_PRECREATE * 2. If its more than that
then the LASSERT is valid.

LU-1606 api: Do not include lustre_idl.h from lustreapi.h

lustre_idl.h has become increasingly difficult to use from
user-space.  Normal users of the lustre api should not
be looking into lustre wire protocol anyway, so this change
eliminates the include of lustre_idl.h.

After removing lustre_idl.h, it became obvious that a number
of programs have been picking up normal user-space headers
through a very windy path of includes.  With the include
of lustre_idl.h gone, they no longer compiled, so we also
add the missing explicit includes.

It became clear that copytool.c explicity requires
libcfs/libcfs.h, and lustre_rsync.c require lustre_idl.h.
But I believe that it is far better to have those includes
explicitly stated, so it is obvious that those programs
are peeking into lustre's internals.  In the future we
can work on creating new lustre API calls that provide the
information that they need without side-stepping abstraction
layers.
