1bdf4a13ae pyocf: Improve volume instance lifecycle handling 
We need a strong reference to volume for as long as OCF has it open.
For that I changed instance tracking dictionary from weakvalue to
normal. This way I made sure that GC won't clean up Volume before its
closed.

e12803f547 Fix for bad metadata capacity reported by dmesg 
Metadata capacity reported by dmesg was actually a memory footprint.

A proper size of metadata is now reported.

5a71f7c068 validate uuid->size in ocf_volume_init 
Optional uuid parameter to ocf_volume_init() points to UUID object
initialized by the user. We should verify it is not excesively large
as we attempt to allocate a buffer to store a copy of the UUID.

364e36ec7e Revert "fix deinitialization of moved composite volume" 
The proper way to avoid calling on_deinit() callback on an already
deinitialized volume is to deinitialize type callbacks, as it is done
in the previous commit.

This reverts commit a7f70687a9.

b6587ad622 zero volume->type in ocf_volume_deinit() 
After deinitialization of volume there is no need to call back to
type ops. Currently we would erroneously call on_deinit() callback
multiple times if ocf_volume_deinit() is performed more than once,
which we expect to happen and treat as a correct use of API.

f0f6ff219b Set core volume type in metadata on core insert 
ocf_metadata_flush_superblock() is being called on the cache stop, after
deinitialization of the cores (and their volumes), thus accessing core
volume in superblock flushing procedure leads to use-after-free bug.

Fix this by moving volume type setting to the core insertion code.
