cleanup: removed last references to globals from client
- There were some refs in SyntheticClient to g_(ceph_context|conf), I
replaced them with client->cct and client->cct->_conf.
- There were some refs in fuse_ll to g_conf, also replaced them with
client->cct or cfuse->client->cct where applicable.
This makes everything in src/client completely independent from globals.

osd: initial COPY_FROM (not viable for large objects)
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.

objecter, librados: add COPY_FROM operation
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.

rgw: change watch init ordering, don't distribute if can't
Backport: dumpling
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.

osd: provide better version bounds for cls_current_version and ENOENT replies
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.

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.

osd_types: add pg_pool_t cache-related fields
We add fields sufficient to specify
* many pools have a tiering relationship with pool foo
* pool foo is a tier pool for pool bar
* the tiering relationship between foo and bar is specified
by cache_mode
* client reads and writes for pool foo should be directed to
pools bar and baz, respectively (where probably, but not
necessarily, baz == bar or baz == foo).
This lets us specify very sophisticated caching policies on
the server side that all clients going forward can handle
simply by directing the messages as the read_tier and write_tier
flags, and the (not-yet-implemented) redirect replies
from OSDs, specify.
