cosd,OSD: Improve filestore upgrade path
Previously, fsconverter was required to update an osd filestore to the
most recent version. cosd will now handle that automatically on
startup. cosd --convert-filestore will also update the FileStore
to the most recent version.

client: drop mostly-useless relink()
Just use unlink() and then link(). Carry an inode ref to avoid badness.
The relink() is left over from a simpler time when we didn't do proper
refcounting.

client: fix readder result merge
When merging readdir results into the cache, we want to remove any names
_preceeding_ the current item before updating it. Then, at the end, we
clean up the trailing items.
This fixes a cfuse crash on workunits/snaps/snaptest-2.sh.

FileStore: On mount, scan collections for unstable state
CollectionIndex implementations may perform compound operations
leaving invalid state if interrupted. index->cleanup() gives
the implementation an oportunity to cleanup any in-progress
operation. For HashIndex, split and merge fall in this
category

FileStore: Add filestore version stamp
A filestore will now be tagged with a version stamp during
mkfs. If on mount the version stamp detected lags the current
version, the mount will fail unless filestore_update_collections
is set in gconf. If it is set, opening a collection will cause
the version stamp on the collection to be read and the
appropriate indexing implmentation to be used. This will allow
for conversion from old collection indexing schemes to new
ones.

osd/: fix hobject_t construction
sobject_t requires only an object_t and a snapid_t. hobject_t also
requires the hash which should be used for the object. In most cases,
the osd must fill this in using the op message. In cases where the hash
used does not matter (as in the metadata collection), the explicit
hobject_t(const sobject_t &) constructor supplies a hash.

First draft of the documentation overhaul.
To build the docs, run ./admin/build-doc. To browse them, either get
them on any static website, or just run ./admin/serve-doc to serve
them quickly off of port 8080.
build-doc sets up a virtualenv to avoid needing Sphinx installed
system-wide. serve-doc needs thttpd installed.

mon: health not ok when up < in osds
We were warning if there were any not up or in osds. Instead, warn if
there are any osds that are in but not up. That means if a node fails
and successfully marks the node out and retracts onto remaining nodes, the
ceph cluster is healthy again.
Presumably the fact that the nodes failed should raise other alerts,
because those specific daemons/nodes are not healthy.

objectcacher: only want for commit
There was some old, weird stuff going on here where we would wait for the
ACK and COMMIT separately. This is just wrong. Writeback does not
complete until the data is committed on disk.
Simplify by waiting only for commit, removing all the 'ack' code, and
going back to a single callback (flush_set).

mds: server: should apply new layout settings on top of old layout
This way, the MDS can handle updates of some values without needing
the user to specify the entire layout (ie, they can just switch pools).
This brings the behavior more in line with setting the dir layout.
