Add bucket quota threshold so that when we're passed that value we
reread the bucket stats before every write and not rely on cached value.

Leverage the cache lru_map locking for making sure that we don't end
up with more than a single concurrent async update on the same bucket
within the same update window.

make MDCache::populate_mydir() only fetch bare-bone stray dirs.
After all stray dirs are populated, call MDCache::scan_stray_dir(),
it fetches incomplete stray dirs.

Although fsstress was being called with a static path the directory
it was writing to was in the current directory so doing a cd to the
source directory that is made in /tmp and then removing it later
caused it to be unable to write the files in a non-existent dir.
This change gets the current path first and cd's back into it after
it is done compiling fsstress.
Issue #6479.

It appears that the OSD is not filling in the individual return codes, and they
should be equivalent for all purposes we care about here (the only Op we are
doing is the copy-get, and if it fails we are getting its failure code).

Fix bug in compress() when compressing to less than .5 or original.
Make the argument have sane units (target size relative to current size;

We need to compensate for the fact that there are fewer bits than there
used to be.
This is a crappy adjustment; it is non-linear. It's clone enough for now,
though.

The RPM spec file currently lists `junit` as a dependency on all
platforms except recent versions of OpenSUSE. This is problematic
because `junit` refers to version 3.x, which doesn't satisfy the check
in the configure script:
configure: Cannot find junit4.jar (apt-get install junit4)
As a result, rpmbuild doesn't build `libcephfs-test.jar` and fails:
http://tracker.ceph.com/issues/6216
So let's depend on `junit4` in all cases. This package is provided by
all supported platforms (el6, fc17, fc18, fc19, opensuse12.2,
opensuse12, sles11), and my testing on CentOS 6 shows that rpmbuild
now succeeds and produces the expected `libcephfs_jni1` RPM.
Note that a bunch of stuff we thought would go in 0.70 is actually in 0.69,
so the update/release notes were adjusted accordingly.

We were storing table_size_ and raw_table_size_, where one is the size in
bits and the other is the size in bytes. This is silly. Store only the
size in bytes.
Also, bytes are always 8 bits, so use bit shifts and drop some of that
silliness too.
Move the member declarations to the top of the class so you read them

If client has outdated directory fragments information, it may request
readdir an non-existent directory fragment. In this case, the MDS finds
an approximate directory fragment and sends its contents back to the
client. When receiving a reply with fragment that is different than the
requested one, the client need to reset the 'readdir offset'.
