Revert "msg/async/Protocol*: send keep alive if existing wins"

This reverts commit 61b9432ef9a3847eceb96f8d5a854567c49bbf61.

If we are in the middle of replacing, we can not queue any further
write events into the old center because we may end up replacing
existing connection's center with a new one, and hence executing
the newly queued write events in the old thread.

See **transfer_existing** for a detailed description.

Also the patch does not make a lot of sense for the original issue
it tried to resolve, because **send_keepalive** is a pure noop if the
underlying connection is not ready, which is obviously true for the
case demonstrated in http://tracker.ceph.com/issues/38493..

osdc/Objecter: preserve read-into-existing-buffer behavior

The libradosstriper::RadosStriperImpl::aio_read populates the target
outbl with a static buffer and relies on us reading into it.  This was
actually not reliable in the past (it could fail if the rx_buffers
optimization failed due to a retransmit or something else) but nevertheless
libradosstriper requires it to work *at all*.

Resolve this by modifying Objecter to copy the result into any provided
buffer at the lowest layer.  This should capture any other such user who
needed this behavior.

On the other hand, it will break any user who inadvertantly reads into a
non-empty bufferlist.  Given that any such user would already previously
have seen bad behavior due to the rx_buffers optimization, we expect
there to be 0 such instances.

qa/standalone/osd/pg-split-merge: fix import_after_merge_and_gap

This test introduces a map gap.  What *should* happen is that when there is
such a gap, we cannot import.  Previously, the test didn't reliably produce
a map gap at all, and didn't check that import failed--it verified that it
passed.

Fix the test so that it reliably produces a gap *and* reports
min_last_epoch_clean to the mon so we can trim.  Then verify we fail to
import, but can with --force.  But remove the pg again, because if we
force an import with a map gap the osd will refuse to start.

ceph-osd: infer objectstore type of 'type' file is missing

The current value of osd_objectstore should have no bearing--we should
rely on the state in front of us.

- If there is a directory called current/, assume filestore.
- If there is a symlink called block, assume bluestore.
- If we see none of those, fail.

mgr/dashboard: fix for using '::' on hosts without ipv6

CherryPy throws an uncaught exception using '::' when the host does not
have an ipv6 loopback address. This is currently the case in kubernetes.
This patch disables the routine in cherrypy that performs the validation
that requested server ports are actually bound.
