rgw: move generic server usage after all options

Since generic_server_usage() exits after printing the options, any other
help options should be printed before that. Now the help for radosgw
looks like the following:

```
usage: radosgw [options...]
options:
  --rgw-region=<region>     region in which radosgw runs
  --rgw-zone=<zone>         zone in which radosgw runs
  --rgw-socket-path=<path>  specify a unix domain socket path
  -m monaddress[:port]      connect to specified monitor
  --keyring=<path>          path to radosgw keyring
  --logfile=<logfile>       file to log debug output
  --debug-rgw=<log-level>/<memory-level>  set radosgw debug level
  --conf/-c FILE    read configuration from the given configuration file
  --id/-i ID        set ID portion of my name
  --name/-n TYPE.ID set name
  --cluster NAME    set cluster name (default: ceph)
  --version         show version and quit

  -d                run in foreground, log to stderr.
  -f                run in foreground, log to usual location.
  --debug_ms N      set message debug level (e.g. 1)

```
This should sync the help options displayed similar to man page options
in current master.  This should close documentation bugs #8112 & #8864

mds: fix crash killing sessions without conn

Bug was introduced in 54eca56695  (mds: use Connection::mark_down()).
Used to call SimpleMessenger::mark_down, which had a check for
connection==NULL, when calling conn->mark_down() we must
now do our own nullness check.

rgw: use a separate callback for civetweb access log

Access log is separate from the regular civetweb logging. Also, changed
the log level for the regular logging as it's used mostly for error

ReplicatedPG::start_flush: remove superfluous loop

Signed-off-by: Samuel Just <sam.just@inktank.com>
ReplicatedPG:start_flush send a second delete

Suppose we start with the following in the cache pool:

30:[29,21,20,15,10,4]:[22(21), 15(15,10), 4(4)]+head

The object doesn't exist at 29 or 20.

First, we flush 4 leaving the backing pool with:

3:[]+head

Then, we begin to flush 15 with a delete with snapc 4:[4] leaving the
backing pool with:

4:[4]:[4(4)]

Then, we finish flushing 15 with snapc 9:[4] with leaving the backing
pool with:

9:[4]:[4(4)]+head

Next, snaps 10 and 15 are removed causing clone 10 to be removed leaving
the cache with:

30:[29,21,20,4]:[22(21),4(4)]+head

We next begin to flush 22 by sending a delete with snapc 4(4) since
prev_snapc is 4 <---------- here is the bug

The backing pool ignores this request since 4 < 9 (ORDERSNAP) leaving it
with:

9:[4]:[4(4)]

Then, we complete flushing 22 with snapc 19:[4] leaving the backing pool
with:

19:[4]:[4(4)]+head

Then, we begin to flush head by deleting with snapc 22:[21,20,4] leaving
the backing pool with:

22[21,20,4]:[22(21,20), 4(4)]

Finally, we flush head leaving the backing pool with:

30:[29,21,20,4]:[22(21*,20*),4(4)]+head

When we go to flush clone 22, all we know is that 22 is dirty, has snaps
[21], and 4 is clean. As part of flushing 22, we need to do two things:
1) Ensure that the current head is cloned as cloneid 4 with snaps [4] by
sending a delete at snapc 4:[4].
2) Flush the data at snap sequence < 21 by sending a copyfrom with snapc
20:[20,4].

Unfortunately, it is possible that 1, 1&2, or 1 and part of the flush
process for some other now non-existent clone have already been
performed.  Because of that, between 1) and 2), we need to send
a second delete ensuring that the object does not exist at 20.
