FileJournal: adjust write_pos prior to unlocking write_lock

In committed_thru, we use write_pos to reset the header.start value in cases
where seq is past the end of our journalq.  It is therefore important that the
journalq be updated atomically with write_pos (that is, under the write_lock).

The call to align_bl() is moved into do_write in order to ensure that write_pos
is adjusted correctly prior to write_bl().

Also, we adjust pos at the end of write_bl() such that pos \in [get_top(),
header.max_size) after write_bl().

debian: make radosgw require matching version of librados2

...indirectly via ceph-common.  We get bad behavior when they diverge, I
think because of libcommon.la being linked both statically and dynamically.

udev: install disk/by-partuuid rules

Wheezy's udev (175-7.2) has broken rules for the /dev/disk/by-partuuid/
symlinks that ceph-disk relies on.  Install parallel rules that work.  On
new udev, this is harmless; old older udev, this will make life better.
