Sage Weil 6679c27459 osd: move to boot state if down OR wrong address in map
Saw an OSD that was up in the map, but the address didn't match.  Caused
all kinds of strange behavior.  I'm not sure what I had in mind when the
original test only checked for down AND same address before moving to boot
state, since having the wrong address is clearly bad news.

 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
