Since snapshots never change, it's safe to read from replicas for them.
A common use for this would be reading from a parent snapshot shared by
many clones.
Convert LibrbdWriteback and AioRead to use the ObjectOperation api
so we can set flags. Fortunately the external wrapper holds no data,
so its lifecycle doesn't need to be managed.
Include a simple workunit that sets the flags in various combinations
and looks for their presence in the logs from 'rbd export'.

This uses the old stand-alone qemu-iotests repo so it works with the
version of qemu in Ubuntu 12.04. The tests depend tightly on qemu
version, so to use later tests we'd need to install corresponding
versions of qemu.

unit tests are added in test/filestore/store_test.cc for the
FileStore::_detect_fs method, when using ext4. It tests the following
situations:
* without user_xattr, ext4 fails
* mounted with user_xattr, ext4 fails if filestore_xattr_use_omap is false
* mounted with user_xattr, ext4 succeeds if filestore_xattr_use_omap is true
The tests are grouped in an ext4 dedicated class
TEST(EXT4StoreTest, _detect_fs)
The qa/workunits/filestore/filestore.sh script is added to prepare the
environment required for the unit tests ( create an image file,
formats it with ext4 etc.). It runs ceph_test_filestore with a sudo
to allow it to mount(2) and umount(2) the ext4 file system. It is
called with
ceph_test_filestore --gtest_filter=EXT4StoreTest.*
to only run the ext4 dependent tests.
The filestore.sh script is meant to be used as part of teuthology
in order to increase the code coverage for src/os/FileStore.cc. It is
self tested and can be checked from the source directory with
CEPH_TEST_FILESTORE=../../../src/ceph_test_filestore filestore.sh TEST

Remove now superfluous directory changes
that are causing tests to fail.
This code should have been removed when we transitioned
from running tests with Ant to using Java to run the tests.

This script uses the python bindings to libcephfs and rados
to create files and check the correctness of the backtrace
written to the 'parent' xattr on the first object (if its
a file) or inode (if its a dir). The script includes test cases
that kill the mds at specific kill points and restart it through
teuthology using the teuthology restart task.

qa/workunits/rbd/test_lock_fence.sh runs using test/rbdrw.py
rbdrw.py creates an image, locks it, and runs an I/O loop;
test_lock_fence.sh runs it, waits, and then blacklists that client,
which causes rbdrw.py to get ESHUTDOWN on operations thereafter.
Currently doesn't work with rbd caching enabled.
rbd.py gets new exception type for ESHUTDOWN
