remove tdir creation from run_one: the test has to create tdir by

- fixed handling for OBD_FAIL_$PREF_$OPC_NET fail_ids in mdt. Former code did not
check it correctly (due to typo with && instead of &) in mdt_req_handle() and
they all did not work. In same time, some handlers like mdt_close() and
mdt_enqueue() tried to check them again (result of some wrong fix) but again, did
it not correctly. They returned 0 error without doing anything. This should
have to emulate network failure. But as they did not allocate reply buffer and
returned 0 error, they caused rs != NULL assert in ptlrpc. Fxing this also fixed
replay-single.sh test_53* and replay_dual.sh test_12 and possibly others;

- removed checking for NET fail_id in mdt_close() and mdt_enqueue() - sources
of recent assert;

- added sanity check in mdt_req_handle() for any other invalid situation about
returning 0 error and not allocating reply buffers;

- removed mdt_reply(), move its one line call into mdt_req_handle(). This was
needed to simplify handling NET fail_ids in which case we should just return 0
and make sure that no reply is sent;

- comments and cleanups;

- in reply-dual.sh - remove test 8 from ALWAYS_EXCEPT. It passes in HEAD.
Originally for placed into ALWAYS_EXCEPT for old mds code and later moved to
HEAD test scripts but as mds in HEAD is completely new this bug is making any
sense there;

- in reply-single.sh - remove tests 0b 39 56 from ALWAYS_EXCEPT. They are
passing in HEAD. Also they are obsolete and related to closed bugs.

Cleanup PATH in tests so absolute paths are used, and
each path is added at most once.

Set fail_loc properly on remote mds.
Abort test if zconf_mount $MOUNT2 fail.

Remove extra blank lines.

 - drop fail_loc to 0 in test 20

 - unit test for "AST during recovery" case

 - sanity tests for the bug

sanityN, sanity-ldlm.

- changed mds_alloc_inode_sid() to allocate lustre_id in memory if there is
no passed one. This makes mds stuff do not use lustre_id allocated on stack
if there is only need to allocate inode sid without using it later. This
makes stack consumption smaller by 40 bytes in each such a case.

- in mds_setup() whrn comparing strings passed from userspace use strncmp()
- root lustre_id should be set up also in cases when there is no profile.
- making do not use lustre_id allocated on stack in places where it is possible.

- moving mds_finish_transno() calling to place where dput() for dchild is
already called to make sure, that unlink op got to current transaction.

- lots of changes in lconf. MDSDEV stuff is changed substantionaly. Removing
bugs prone code, replacing it by new one about setting up MDS, LMV, etc.
Added more verbose messages about MDS, LMV configuration. Removed redundant
stuff about forming mount options. It now is moved to function and be used from
few places.

- fixes in CMOBD and COBD objects about using LMV.

- fixed double client_ref adding to LMV, what led to double client config
writing on MDS setup.

Handle server recovery in a new thread, instead of tying up request
processing threads. Centralizes the recovery management, including the
abort recovery checking.

update replay-dual.sh and replay-ost-single.sh

- landed on HEAD
