mon: set limit so that we do not an entire down subtree out
Add new configurable 'mon osd down out subtree limit' so that you can
prevent marking out an entire subtree. If for example an entire rack is
down, do not mark anything in it out. If less than the whole rack is down,
everything is fair game.

mon: Monitor: rework timecheck code to clarify logic boundaries
The initial timecheck implementation relied on a cleanup function to
clean the state each time we changed epochs (or we got out of quorum),
and we would have to clean up the state in-between rounds in a potentially
confusing way some time down the line.
This patch creates logic boundaries in the code flow, making it clear
where we set up or clear the state when we start or finish an epoch, and
where we set up or clear the round state in-between rounds. It also
allowed for some other changes in behavior, such as when we set-up the
timecheck event, or when we cancel it. Despite the slight increase in
size, the mechanism just got more easily understandable than it was before.

mon: Elector: reset the acked leader when the election finishes and we lost
Failure to do so will mean that we will always ack the same leader during
an election started by another monitor. This had been working so far
because we were still acking the existing leader if he was supposed to
still be the leader; or we were acking a new potentially leader; or we
would eventually fall behind on an election and start a new election
ourselves, thus resetting the previously acked leader. While this wasn't
something that mattered much until now, the timechecks code stumbled into
this tiny issue and was failing hard at completing a round because there
wouldn't be a reset before the election started -- timechecks are bound
to election epochs.

rbd-fuse: add simple RBD FUSE client
Currently written in C on FUSE hi-level interfaces, so error reporting

Images may be truncated or extended by rewriting. Currently
once an image is opened, it's not closed, so it can't be deleted

s3/php: update to 1.5? version of API
Something like v1.5 of the Amazon PHP library requires the AmazonS3

v1.5 while we do that research.

doc: wider sidebar, larger font, cleaned tip CSS
The sidebar is now about a hundred pixels wider and the fonts
are larger throughout. This works a lot better when you get
deep into the doc structure - it used to wrap horribly.
I also fixed how literals look inside .tip and .important.
For some reason, the lookup() retry loop (for when happened to
race with a removal and grab an invalid WeakPtr) locked
the lock again. This causes the #3836 crash since the lock
is already locked. It's rare since it requires a lookup between
invalidation of the WeakPtr and removal of the WeakPtr entry.

it is generally bad for non-btrfs writeahead mode.
