LU-1187 tests: Fixes in test-framework for DNE

1. Add dev parameter to mkfs_opts, so it can check if it needs
--mgs for dev. combined_mgs_mdt is only useful for mdt0.
2. Add multi-node facet failover support, so it can fail multiple
targets at the same time.
3. Remove mdsn_HOST/failover_HOSTs in local.sh and add them to
facet_host.
4. replace MDSDEV1 and MGSDEV with mdsdevname and mgsdevname, because
these vars are not always defined.

it is better to deliver CANCEL rpc to server reliably in the case of:

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
  51:osp_precreate_cleanup_orphans()) lustre-OST0000-osc-MDT0000: Got
  last_id 130 from OST, last_used is 36, pre_used 130
  ...
  00000004:00080000:1.0:1353838616.328935:0:14230:0:(osp_precreate.c:7
  42:osp_precreate_reserve()) lustre-OST0000-osc-MDT0000: precreated 1
  : opd_pre_last_created 131 opd_pre_used_id 130 opd_pre_reserved 0
  00000004:00080000:1.0:1353838616.329173:0:14230:0:(osp_precreate.c:8
  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-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.

LU-1623 mdt: Atomically update MDT export connection flags

MDT processing of connect requests currently updates the export
connection flags in two steps: client/server feature matching is
performed first, then much later various security-related bits are
removed as needed.  Certain error paths may leave the export flags
partially initialized.

A problem arises if multiple connect requests from the same client are
handled out of order, as may occur due to network disruptions. If the
last such request to be handled has a lower connection count than one
that already completed, it will be aborted with -EALREADY after having
modified the connection flags in the export.  However, the
security-related flags are left with incorrect values, as the
top-level connect handler skips setting these in the error path.
Replies to subsequent client requests may then contain unexpected
security information, causing the client to crash.

Similar issues may exist with other target types having non-atomic
export flag updates, and these should be addressed in follow-up
patches.

This patch makes the following changes:

- To avoid the problem described above, update the export connection
  flags atomically, and only in the successful case.

- To make this important atomic operation more conspicuous, move it
  from mdt_init_sec_level() to the top-level handler mdt_connect().

- Add a comment to mdt_connect_internal(), and delete a disabled code
  block from it.

- Correct debug message in target_handle_connect() to match code.

DCACHE_LUSTRE_INVALID is lustre private flag in vfs layer.
Replace it with dentry->d_fsdata->lld_invalid so that it won't

LU-1199 build: Remove duplicate LC_MODULE_LOADING

It appears that LC_MODULE_LOADING was accidentally declared twice
back-to-back in the same file.  This removes the first declaration
on the assumption that if my eye-balling of the code missed a
difference, the second one is the one we've been using anyway.

LU-1714 lnet: Properly initialize sg_magic value

When the CONFIG_DEBUG_SG flag is enabled in the kernel, we must ensure
the sg_magic field is properly initialized. Otherwise, internal kernel
assertions will fail when trying to verify this field. As a result,
certain calls to sg_* function had to be changed or inserted to ensure
the sg_init_table function would be called, initializing the magic
value. Also, we need to ensure this value isn't zeroed out in the
kiblnd_setup_rd_kiov function.

LU-1337 llite: provides ll_get_acl to ->i_op->get_acl

Since kernel 3.1 generic_permission() has lost the check_acl
argument, ACL checking has been taken to VFS and filesystems
need to provide a non-NULL ->i_op->get_acl to read an ACL

This patch is a complementarity to http://review.whamcloud.com/3397

LU-1337 llite: kernel 3.1 changes open_to_namei_flags

Kernel 3.1 changes the translation from open_flag to namei_flag,
(kernel commit 8a5e929dd2e05ab4d3d89f58c5e8fca596af8f3a).

So after 3.1, kernel's nameidata.intent.open.flags is different
with lustre's lookup_intent.it_flags, as lustre's it_flags'
lower bits equal to FMODE_xxx while kernel doesn't transliterate
lower bits of nameidata.intent.open.flags to FMODE_xxx.

This patch keeps lustre it_flags' semantics and add
ll_namei_to_lookup_intent_flag for translation.
