SimpleMessenger: Keep a disposable flag for use in reset
pipes marked disposable must not inherit the lossy policy on reconnect.
Also, in Pipe::writer, when sent.empty() && close_on_empty, mark as
lossy to ensure that fault will close the connection.

rados_bencher: re-add written objects constraint to read benchmark.
Somehow, in the last major change, the constraints that kept the
bencher from trying to read non-existent objects got removed. Put
a check back in the main bench loop to fix that.

filestore: stat to test for file type if d_type is unsupported
This only affects list_collections. Previously, when using an FS that
does not support d_type, like xfs, load_pgs would fail to find any
pgs, since list_collections skipped all files.
This made clients hang because all pgs were considered non-existent by
the osd.

osd: ignore old/stale heartbeat messages
If we get heartbeat messages from old epochs from peers that are not
current, drop them and mark the connection down. Even if they are peers
we _should_ have (because we haven't gotten a notify yet to learn about
a pg we should have but don't yet) we have a newer map epoch and will learn
about them shortly, reopening the connection.

mds: fix canceled lock attempt
If client tries to lock a file, has to wait, and then cancels the attempt,
the client will send an unlock request to unwind its state.
- the unlock now removes the waiting lock attempt from the wait list
- when the lock request retries and finds it is no longer on the wait
list it will fail.

PG: fix race in _activate_committed
Previously, _activate_committed would access the osdmap epoch racing
with handle_osd_map's osdmap update. This would allow a message to be
sent from a replica to the primary tagged with the same epoch as
last_warm_restart, though the event actually occured before
last_warm_restart. Thus the primary would fail to ignore the event and
transition to crashed.

mds: do not shift to EXCL or MIX while rdlocked
There was an old change in file_eval() that was allowing us to switch from
SYNC to MIX or EXCL while there were rdlocks, which either caused lots of
lock thrashing or could (I think) hang things up completely. This was
from ea10a672, an ancient fix for something related that appears to have
taken out the rdlocked check by accident.
In my tests (one writer, one stat-er), this took things from long stalls
(up to 20 seconds) to very responsive stats. Yay!

If "rados put" uses write instead of write_full, the resulting object on
the server may be a mismash of old and new objects, if the old object
was longer than the new one. This is fairly counterintuitive behavior
for radostool, so remove it.

osd: add ability to explicitly mark unfound as lost
Instead of automatically marking unfound objects lost (once we've tried
every location we can think of), do it when the administator explicitly
says to. This avoids marking things wrong incorrectly when there are
peering issues, and also allows the administrator to decide whether there
may be offline osds that are worth bringing online.

osd: make automatically marking of unfound as lost optional
We may not want to do this automatically until we have more confidense in
the recovery code. Even then, possible not. In particular, the OSDs may
believe they have contact all possible homes for the data even though there
is some long-lost OSD that has the data on disk that if offline.
For now, we make the marking process explicit so that the administrator can
make the call.
A CephContext represents the context held by a single library user.
There can be multiple CephContexts in the same process.
For daemons and utility programs, there will be only one CephContext.
The CephContext contains the configuration, the dout object, and
anything else that you might want to pass to libcommon with every
function call.
Move some non-config things out of md_config_t and into CephContext.

Split common_init_daemonize from common_init_finish
Split off common_init_daemonize from common_init_finish. cfuse is a
daemon that calls common_init_finish, but handles daemonization itself.

Get rid of the initialize-then-shutdown-crypto hack. We just initialize
crypto once, after it is safe to do so. There is now a single callback,
common_init_finish, which does the final stage of initialization,
including starting crypto and daemonization (if required.)
common_init_finish needs to be done before messenger::start().
