libceph: move feature bits to separate header This is simply cleanup that will keep things more closely synced with the userland code. Signed-off-by: Sage Weil <sage@inktank.com> Reviewed-by: Alex Elder <elder@inktank.com> Reviewed-by: Yehuda Sadeh <yehuda@inktank.com>

libceph: support crush tunables The server side recently added support for tuning some magic crush variables. Decode these variables if they are present, or use the default values if they are not present. Corresponds to ceph.git commit 89af369c25f274fe62ef730e5e8aad0c54f1e5a5.

ceph: Check for created flag in response from mds The mds now sends back a created inode if the create request performed the create. If the file already existed, no inode is returned in the reply. This allows ceph to set the created flag in atomic_open so that permissions are properly checked in the case that the file wasn't created by the create call to the mds. To ensure compability with previous kernels, a feature for sending back the inode in the create reply was added, so that the mds will only send back the inode if the client indicates it supports the feature.
