Sage Weil 4a7c3553a7 osd: avoid most of handle_osd_map if there are no new maps in message

usually the case).

 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/

         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
