Returning the current version for the pgid and last_user_version makes
some sense here.

Initial pass at COPY_FROM implementation. This uses COPY_GET to read an
object from another OSD and write it locally. It chunks the read but
accumulates it all in-memory and commits it at once, so it is only suitable
for smaller objects.

This operation will copy an entire object (data, attrs, omap)
atomically. If the src_version does not match the source object, or
the source object is updated while the copy is in progress, we will
fail with a suitable error code. By atomic we mean that it will either
successfully copy the entire object in its entirety or it will fail (and
require no cleanup).
Add to C++ librados API only for now.

Moving back the watch initialization after the zone init,
as the zone info holds the control pool name. Since zone
init might need to create a new system object (that needs
to distribute cache), don't try to distribute cache if
watch is not yet initialized.

Following the changes to when we set or increase the user_version, we
want to continue to return the best lower bound we can on the version
of any newly-created object. For ENOENT replies that means returning
info.last_user_version instead of the (potentially-zero) ctx->user_at_version.
Similarly, for cls_current_version we want to return the last version on
the PG rather than the last update to the object in order to provide
sensible version ordering across object deletes and creates.
Update the versions doc so it continues to be precise.

Leave ctx->user_at_version set to the previous oi.user_version unless/until

We may have pg entries that do not increase the user_version at all (i.e.,
they may be 0). Do not update the last_user_version in that case as we
need it to remain an upper bound.

Make sure we don't dereference a NULL pointer. Note that we check a
bit further down if the target pool does not exist and return the proper
error.

Separate the processing of an OpContext from the preamble and
allocation, so that we can delay the execution for some ops (like the
COPYFROM operation we're about to add).

Feed every map message we see (that isn't discarded for some other
reason) to the Objecter. It has the same continuity requirements that
the OSD has, so it should be satisfied with what we get. It can also
request maps via our MonClient.

We will give the OSD's Objecter its own messenger so that it does not
