42d6dbbf11 Remove low-level stats getters from public API. 
Since stats builder is implemented for retrieving cache, core and ioclass stats,
adapters should use it instead.

d10c618065 Move parts metadata to separate section 
Fix problem introduced by increasing partition name size to 1024 bytes,
which effectively made superblock bigger than one page. Due to this
flushing superblock required more than one io, which in case of dirty
shutdown between these ios resulted in CRC missmatch and made cache
recovery impossible.

Moving parts metadata to separate sections makes superblock fitting
in one page, effectively solving described problem.

Merge pull request #227 from mmichal10/mark-core-added-false 
Don't try to remove invalid cores

If valid cache metadata was read, but environment has changed (i.e. number of cache lines has changed) ocf (in error handling path) was trying to close cores which were not opened. It happened due to cores were marked in cache metadata as added, but any cache inserting operation didn't take place.

In this patch 'added' flag in cache metadata was replaced with more meaningful 'valid' - it is set if given core is stored in cache metadata. Moreover, new 'added' flag was added to core run-time metadata and it is set if given core is added to cache.
