configure.ac: add --disable-gitversion
During development each git commit cause currently a complete
rebuild of the source tree. By passing --disable-gitversion to
configure we set a generic version string for ceph to prevent
getting after each commit a new version set.
remove src/check_version and replace with a extended version
of src/make_version which allows detecting changes in .git_version
and ceph_ver.h to avoid not needed updates.
This change also forces to call make_version each time to make
sure that changes from configure or the NO_VERSION env variable
are processed.

osd: erasure-code-profile incremental rm before set
It is possible for an incremental change to have both a rm and a set for
a given erasure code profile. It only happens when a rm is followed by a
set. When a set is followed by a rm, the rm will remove the pending set
in the incremental change.
The logic is the same for pool create and pool delete.
We must apply the incremental erasure-code-profile removal before the
creation otherwise rm and set in the same proposal will ignore the set.
This fix is minimal. A better change would be that erasure-code-profile
set checks if there is a pending removal and wait_for_finished_proposal
before creating.

mon: informative message when erasure-code-profile set fails
When erasure-code-profile set refuses to override an existing profile,
it may be non trivial to figure out why. For instance:
ceph osd set default ruleset-failure-domain=host
fails with:
Error EPERM: will not override erasure code profile default
although ruleset-failure-domain=host is documented to be the
default. The error message now includes the two profiles that have been
compared to not be equal so that the user can verify the difference.
Error EPERM: will not override erasure code profile default
because the existing profile
{directory=.libs,k=2,m=1,plugin=jerasure,technique=reed_sol_van}
is different from the proposed profile
{directory=.libs,k=2,m=1,plugin=jerasure,ruleset-failure-domain=host,technique=reed_sol_van}

If stray inode has no snapshot data, it's OK to purge it even if

mds: fix fnode.snap_purged_thru check
We do not alway succeed in purging all stale snap dentries
(stale snap dentris can be in-use or have been trimmed from
cache). Updating fnode.snap_purged_thru prematurely will make
us not purge the remainning stale snap dentries. If CDir
has no cached snap dentry when fetching dirfrag, we can
guaranee that all stale snap dentries will be purged.
So we only update fnode.snap_purged_thru in this case.
Now the code that purges stale snap dentries is executed more
frequently. So this patch also make readdir not purge stale
snap dentries

osd: use (robust) helper for setting exists or clearing whiteout
The current blanket check in prepare_transaction() will trigger only when
there is a net obs.exists change from the commited obs to new_obs.
However, this misses the case where the first osd_op is a delete and then a
subsequent osd_op recreates the object. Changing the whiteout check to
look only at new_obs does not work because it fails to understand when
_delete_oid sets the whiteout and will simply clear it again.
In order to support sequences of delete + create in general, we need to do
the whiteout flag clearing when the actual create happens (to match the
fact that we set it when we process the delete osd_op). Use a helper to
do this and consolidate most other obs.exists = true code to use it.
