removal in on_removal().

os/FileJournal: do not request sync while shutting down

FileStore calls should_commit_now() to determine whether it should
loop and do a second sync (among other things).  During shutdown, this
can force us into a livelock: the journal is shutting down, but the
sync_entry loop never completes and repeatedly syncs because the
journal is full.  Since the journal is otherwise stopped, no expire
happens and we never become unfull, and we're stuck.

This seems to be triggered semi-reliably by the ceph_objectstore_tool
import function.

Fix by not requesting a sync while shutting down.

osd/ReplicatedPG: do not clone or preserve snapdir on cache_evict

If we cache_evict a head in a cache pool, we need to prevent

common: LogEntry: if channel is missing, default to "cluster"

Keeps backward compatibility when there are entities that do not know
what a channel is.  This way we ensure that those messages are logged as
they were expected to be before channels were introduced: to the cluster
log.

mon: LogMonitor: appropriately expand channel meta variables

We must only expand the log file's channel meta variables upon requiring
a channel's log file.  As we may have a 'default' channel that will
cover all channels, we must wait to expand channels as they come in and
do so if they haven't yet been expanded.  Expanding the 'log_file' in
place would have the unfortunate side effect of expanding, say,

default=/tmp/whatever.$channel.log

to

default=/tmp/whatever.default.log

which would not be what we wanted upon receiving a message that should
go into channel 'foo' -- assuming we specified no such channel in the
options, channel 'foo' should go into '/tmp/whatever.foo.log'.
