Colin Patrick McCabe a4138c9050 osd: generalize coll_t to a string
coll_t is now a string. META_COLL and TEMP_COLL are just constants now.

Now there is a constructor that takes pgid_t and snapid_t, rather than
factory methods. It's clear what that constructor does, so wrapping it
in factory methods should be unecessary.

Bump coll_t serialization version to 3. Implement decoding for the old
versions.

Ceph - a scalable distributed file system
-----------------------------------------

Please see http://ceph.newdream.net/ for current info.

----

To build the server daemons, and FUSE client,

$ ./autogen.sh
$ ./configure

$ make
 or
$ cd src
$ make

(Note that the FUSE client will only be built if libfuse is present.)

----

A quick summary of binaries that will be built in src/

daemons:
 cmon -- monitor daemon.  handles cluster state and configuration
         information.
 cosd -- storage daemon.  stores objects on a given block device.
 cmds -- metadata daemon.  handles file system namespace.
 ceph -- send management commands to the monitor cluster.

userland clients:
 cfuse -- fuse client.
 csyn -- synthetic workload generator client.

tools:
 monmaptool -- create/edit mon map
 osdmaptool -- create/edit osd map 
 crushtool -- create/edit crush map

scripts:
 mkcephfs -- cluster mkfs tool
 init-ceph -- init.d start/stop script
