ReplicatedBackend: don't queue Context outside of ObjectStore with obc

We only flush the ObjectStore callbacks, not everything else.  Thus,
there isn't a guarrantee that the obc held by pull_complete_info will
be cleaned up before the Flush callback is triggered.  Instead, just
defer clearing the pull state until the callback (it'll be cleaned up
during the interval change) and remove the ObjectContext from
pull_complete_info.

radosgw/swift: clean up flush / newline behavior.

The current code emits a newline after swift errors, but fails
to account for it when it calculates 'content-length'.  This results in
some clients (go github.com/ncw/swift) producing complaints about the
unsolicited newline such as this,
Unsolicited response received on idle HTTP channel starting with "\n"; err=<nil>

This logic eliminates the newline on flush.  This makes the content length
calculation correct and eliminates the stray newline.

There was already existing separator logic in the rgw plain formatter
that can emit a newline at the correct point.  It had been checking
"len" to decide if previous data had been emitted, but that's reset to 0
by flush().  So, this logic adds a new per-instance variable to separately
track state that it emitted a previous item (and should emit a newline).

ceph-disk: Add fix subcommand

This subcommand will fix the SELinux labels and/or file permissions on
ceph data (/var/lib/ceph).

The command is also optimized to run the commands in parallel (per
sub-dir in /var/lib/ceph) and do restorecon and chown at the same time
to take advantage of the caching mechanisms.

messages/MCommand: fix type on decode

Wow, this has been broken since v0.38, but apparently
the message never made it into the object corpus so
we never noticed!

In reality the bug is harmless: decode_message() will
set_header which clobbers whatever version the default
ctor fills in, so this only affects ceph-dencoder's
test.
