librbd: Add a paramter:purge_on_error in ImageCtx::invalidate_cache().

If bh_write met error, it will try again. For closing image, if met this
issue, it will trigger a assert:
>>2015-02-03 15:22:49.198292 7ff62d537800 -1 osdc/ObjectCacher.cc: In

>>2015-02-03 15:22:49.195927osdc/ObjectCacher.cc: 551: FAILED
>>assert(i->empty())

Now add purge_on_error, when shutdown_cache it set true.
In ImageCtx::invalidate_cache, if met error and purge_on_error is true,
purge the dirty bh.

locally.  See commit ff99af38df830e215359bfb8837bf310a2023a4d.

Note that this means upgrades from hammer to post-hammer *must* include

debian/control: ceph-common (>> 0.94.2) must be >= 0.94.2-2

The d8733be2ef8874b9a858a7ffddfb81b9b656e9a6 backport introduced a
regression by adding an incorrect Depends / Break combo supposed to
reflect the fact that ceph_argparse moved from ceph to ceph-common after
v0.94.2. It assumed the package is released under the 0.94.2 version
where in reality it is released under the 0.94.2-1xxx version (where xxx
is trusty, jessie etc.).

The Depends / Break combo is changed to use 0.94.2-2 instead.

ceph.spec.in: drop SUSE-specific %py_requires macro

%py_requires expands to

BuildRequires: /usr/bin/python
PreReq: python = 2.7

The BuildRequires: is already provided, and the PreReq is wrong because
e.g. SLE11-SP3 (a platform we are trying to support) has Python 2.6.

librbd: invalidate cache outside cache callback context

When shrinking an image, it's possible that the op flush callback
will be from within the cache callback context.  This would result
in a deadlock when attempting to re-lock the cache lock in order to
invalidate the cache.
