pybind: Open shared libs by their major version.
The *.so files are only in the -dev packages, and normal
operation should not require those. The major version
numbers represent incompatible API/ABI changes anyway.
The debian dependencies were already correctly including

debian: Properly package the python bindings.
Build-depend on python-support. Add binary package
python-ceph, making it contain all the ceph python
packages, regardless of their name; the modules are
too small to deserve their own debs.
Make python-ceph depend only on librados2 for now.
librgw is not packaged yet.
Dropping unnecessary build-dep on python-dev, that's
only needed for compiling C extensions, and we're using
ctypes.

Thread: remove globals. Thread create must succeed
Remove the references to global variables from Thread.h. They are really
unecessary. In every case, the printout is followed by an assert which
will deliver the exact same information.
Assert that thread creation succeeds. Nobody was checking the return
value of Thread::create() previously. Added a new function,
Thread::try_create(), which programmers can use if they do want to check
the value of Thread::create() and handle it appropriately.

Sometimes we create a Monitor without a Messenger. So we can't pull the
CephContext out of the Messenger, because it may be NULL. Just specify
it explicitly in the Monitor constructor.

mds: xlock_finish should only do_issue in certain cases.
We accidentally (we think) initialized this variable to true when
we want it to be false: we should only do_issue if there aren't
any remaining locks, not in all cases.
De-globalize CephToolContext. It's important to do this now because the
constructor for CephToolContext references the configuration (via
CephContext.)

We actually do want witnesses who aren't auth for anything
to do journaling in some cases, so kill the assert.
That also negates the need for the not_journaling check.

It's possible we have non-auth metadata only because we have a subtree
nested beneath. If we rename a directory out of a non-auth subtree, we
should try to trim any non-auth content from that subtree that may now
be possible due to the child subtrees being linked elsewhere.

mds: remove unlinked metadata from cache on replay
If we replay a metablob that unlinks something, throw it out immediately.
Recursively. This comes up when:
- we rename a file from one mds to another, and we replay the event on
the source mds. the inode gets thrown out.
- we rename a directory from one mds to another, and when journaled, the
source mds had no nested metadata. same thing: we throw it out. we
may have something in our cache nested beneath that, though, that was
since committed and such, but the fact that we didn't journal it being
reattached elsewhere implies that it was clean and gone when our event
was journaled, and we can throw it all out. recursively.

libcommon uses symbols from the crypto libraries, so they must appear on
the link line whenever libcommon appears. Later, we may want to revisit
this dependency; however, right now, having unit tests that build
consistently is pretty important.

mds: open renamed import child frags during journal replay
Open up any child frags of the imported renamed inode that are noted in
the journal event. (Note we blindly open up that list here; it's up to the
journaler to only populate it when appropriate.) If the listed frags are
not already open, open them up and set the dir_auth to unknown; presumably
they belong to the rename source/exporter. If we already had them open,
then the adjust_subtree_after_rename call above will have caught them and
already done the necessary subtree adjustment.

mds: journal renames on witnesses if we have nested subtrees
If a rename witness has any subtrees that are nested beneath the renamed
directory, we need to journal the rename event so that our cache is
properly updated on journal replay.
Further, if we are exporting srci, we also need to journal the dest
(even if we aren't auth for destdn) if we have any open dirfrags because
those will turn into nested subtrees shortly.
We still need to ensure that the cache is properly trimmed during replay.
