Reduce the number of inodes created on larger OST filesystems, since

LU-128 Avoid assertion on wire data in last_rcvd update

- checks that lower transno can't overwrite the bigger one in last_rcvd
  slot.
- evict client if bad transno was sent in replay, this is done by simulating

introduced a clear separation for on the wire and in-memory
policy representations and ways to convert between them.

This makes nfs4 locking work, also fixes original problem with
flock locking of the same fd from different processes. Makes
our own tests/flock_test.c to pass now which it never did before.

LU-210 backout debian packaging with patches

The debian packaging process included the [de-]applicaiton of patches
that were the commits made since the last tag.  This provided greater
transparency as to exactly what was included in a release when it was
made between tags.

Unfortunately the process that was being used to achieve this failed
in a scenario where there were patches to files which were later removed
from the tarball making process.

For what it's worth, the right way to correct this and keep the
transparency is to have "make dist" create the tarball from the most
recent tag made and then have the patches generated that bring the
source up to current HEAD.  In order to achieve this however both debian
and RPM packaging would need to operate in this manner.  That would
mean adding Patch$n: lines to the RPM spec for each of the generated
patches.  I'm not really sure we want to go there though.

LU-84 Allow building against kernel devel headers with quotas

The quota format definitions are normally found in private kernel
headers.  However, some sites build Lustre against kernel development
headers rather than than full kernel source. To accomodate this we add
the minimal set of required definitions to
lustre/include/lustre_quota.h which will take effect only if
quotaio_v*.h are not located at configure time.  The upstream version
of the 64-bit quota format patch in RHEL6 adds QFMT_VFS_V1 to
include/linux/quota.h, so configure can check for that if the
quotaio_v*.h headers aren't found.
