LU-936 Remove LUSTRE_KERNEL_VERSION

Patched kernels are no longer an absolute requirement for
Lustre servers.  Remove the LC_LUSTRE_VERSION_H autoconf
check and all usage of the LUSTRE_KERNEL_VERSION #define.
Going forward any specific kernel dependency should be
expressed with an explicit, clearly documented, autoconf
test.

As part of this change the check for automatically disabling
lustre server support has been moved to the ldiskfs autoconf
checks.  Previously this was done by checking for the
existance of a patched kernel.

LU-1205 tests: sanityn test_18 sometimes takes long time to run

This is a live-lock problem where two processes are writing to the
same mmaped file via two nodes. To write a mmap region, both processes
will do:

  acquire cl_lock -> read page -> release cl_lock-> install page.

During the above steps, the page can be truncated after the lock is
released and then immediately cancelled by the other process, so
kernel has to do page fault again and never complete.

Lustre can't handle this case well so this test case is disabled.

LU-251 Fix gcc configure warnings

Newer versions of gcc are getting smart enough to detect the sloppy
syntax used for the autoconf tests.  It is now generating warnings for
unused or uninitialized variables.  Newer versions of gcc even have the
-Wunused-but-set-variable option set by default.  This isn't a problem
except when -Werror is set and they get promoted to an error.  In this
case the autoconf test will return an incorrect result which will result
in a build failure or runtime error later on.

To handle this I'm tightening up many of the autoconf tests to
explicitly mark variables as unused to suppress the gcc warning.  Tests
emitting uninitialized variable errors are updated to initialize
pointers to NULL, and some variables are converted to pointers to
accomodate this.  'Argument makes integer from pointer without a cast'
errors were fixed by passing 0 for the offending argument in cases where
we are not explicitly testing the argument type.  0 is accepted as both
an integer and a pointer.

LU-1264 quota: reserve FID sequences for quota

This patch reserves 2 FID sequences for quota.

Slave indexes will be allocated an unique FID from the FID_SEQ_QUOTA
sequence.

As for FID_SEQ_QUOTA_GLB, it will be used to uniquely identify the
global quota indexes. For the global index, the sequence will thus be
set to FID_SEQ_QUOTA_GLB and the 32-bit object ID divided into 3
fields:
- 16-bit pool identifier
- 8-bit quota type (user or group quota)
- 8-bit target type (data or metadata)

Thanks to this static FID scheme, slave can enqueue global quota lock
directly on the right FID without requiring a first readdir or to
change the resource ID on the fly when the lock is granted.
As for the slave index FID, it is allocated dynamically from
FID_SEQ_QUOTA and is returned to the slave in the quota LVB when the
global quota lock is granted.

Per the description of "-w" option:

Select only those lines containing matches that form whole words.
The test is that the matching substring must either be at the

character. Similarly, it must be either at the end of the line

characters are letters, digits, and the underscore.

LU-1016 build: no sub-builds in sub-shells

The make program paradigm is to have command failures fail the make.
Invoking a failing "make" in a subshell will cause the subshell
to exit returning non-zero to the invoking shell.  However, the
invoking shell will *NOT* exit.  Therefore, to correctly use a
subshell in a make file scriptlet, use the following template:

  ( do-some-stuff ) || false

this will work as expected.  You want "false" instead of "exit 1"
in case make as been invoked with the "-i" ("--ignore-errors")
option.

WRT the code in question, there really is no need of even using
a subshell.  So this patch fixes two (related) things:

1.  the "for subdir in $(RPM_SUBDIR)" is now done in one process
    and will cause the superior make to stop if any subdirectory
    make fails.

2.  The tests for BUILD_TESTS and BUILD_SERVER for building RPMs
    need to take into account the possibility that these are not
    necessarily defined in all autoMakefile.am's that use the
    autoMakefile.am.toplevel file.

LU-1255 tests: pass $DBENCH_LIB to run_dbench.sh

This patch does:
1) pass the values of $DBENCH_LIB and $DBENCH_SRC to run_dbench.sh
2) redirect the output of tar directly into the $LOG file instead of
   messing up the test output
3) check the $LOGDIR directory inside gather_logs() in case
   this function was called before init_logging()
4) fix check_logdir() and check_write_access() to avoid using
   node.$(hostname -s).yml files which should not be deleted

LU-1244 obdecho: destroy ost objects for md echo client.

Since md echo client connects MDT directly, and there are no
lov for echo client, so it will destroy the ost object in
mdd_unlink directly.

In setxattr test, it should set another EA, instead of LOV,
which would cause problem in the following test.

Reset valid before unlink and getattr.

LPROC_LL_MKDIR, LPROC_LL_RMDIR, LPROC_LL_MKNOD, and LPROC_LL_RENAME

Add LPROC_LL_READDIR for successful calls to ll_readdir().

Tally LPROC_LL_OPEN if and only if the call succeeds.  Under the
previous behavior, opens of a file that was already open locally with
the same flags were not tallied.

Do not tally LPROC_LL_SETATTR when the setattr is from truncate() or
truncate from open().

Tally LPROC_LL_TRUNC when appropriate in ll_setattr_raw(), but remove
tallies in ll_truncate() and vvp_io_init().  Under the previous
behavior, a single call to truncate() caused LPROC_LL_TRUNC to be

not yet landed to our release tree, it is in use in production at
some customers.  While the risk of conflict is currently low, it
is easier to change the GRANT_PARAM value since only in use on the
orion branch, and isn't even handled by the client there yet.

Add (hopefully) clear comments for OBD_CONNECT and obd_connect_data
to ensure that they are not modified in some incompatible way across
branches.
