In EMetaBlob::add_root(), we should log the projected root xattrs
instead of original ones to reflect xattr changes.

MDS crashes while journaling dirty root inode in handle_client_setxattr
and handle_client_removexattr. We should use journal_dirty_inode to
safely log root inode here.

Add libboost-system-dev (bug #4725).
Add hdparm to rpm installation requirements. The hdparm
command is used to determin if write-caching is enabled on
the journal device.

Say a service establishes it will only keep 500 versions once a given
condition X is true. Now say that said condition X only becomes true
after said service committing some 800 versions.
Once we decide to trim, this service would trim all 300 surplus versions
in one go. After that, each committed version would also trim the
previous version.
Trimming an unbounded number of versions is not a good practice
as it will generate bigger transactions (thus a greater workload on
leveldb) and therefore bigger messages too.
Constantly trimming versions implies more frequent accesses to leveldb,
and keeping around a couple more versions won't hurt us in any significant
way, so let us put off trimming unless we go over a predefined minimum.
This patch adds two new options:
paxos service trim min - minimum amount of versions to trigger a trim
(default: 30, 0 disables it)
paxos service trim max - maximum amount of versions to trim during a
single proposal
(default: 50, 0 disables it)

Logging was variously described in the ceph configuration document,
a configuration reference, and a section in operations. Since
logging and debugging are generally used with troubleshooting,
I consolidated the docs and placed them in the troubleshooting
section. Also fixed the example and provided additional detail.

The filter_policy (bloom filter) stuff is fairly new in LevelDB's life,
and it turns out that precise's version is too old for it. Add conditional
compilation for those members in order to build and work properly.

For simplelock and filelock, XLOCK/XLOCKDONE's next state is SYNC.
But filelock in XLOCK/XLOCKDONE state allow Fb caps, filelock in
SYNC state does not. So filelock can be stuck in XLOCK/XLOCKDONE
state forever if there are Fb caps issued.

Store conversion wasn't converting the osdmap_full/ versions, only the
incrementals under osdmap/ and the latest full version stashed. This
would lead to some serious problems during OSDMonitor's update_from_paxos
when the latest stashed didn't correspond to the first available
incremental.
