c83cb7a11d tools/cephfs: add pg_files command 
Sometimes users know that particular data pool PGs
have been damaged, and they would like to scan
their files to work out which ones might have
been affected.

mds: remove max_mds config option 
It is now required that all changes to max_mds use the run-time `ceph fs
set max_mds` command. The rationale for this change is that it is
confusing to have a configuration for max_mds which is only observed at
file system creation.

b6d2b6d1a5 client: report root's quota in statfs 
When user is mounted a quota-restricted inode
as the root, report that inode's quota status
as the filesystem statistics in statfs.

This allows us to have a fairly convincing illusion
that someone has a filesystem to themselves, when
they're really mounting a restricted part of
the larger global filesystem.
