Since OCF doesn't use core and cache ids anymore adapter has to track occupied
ids on its own. After loading cache, ids of all loaded cores should be marked as
occupied, otherwise adding new core without explicit specifying core id will
fail.

Kernel's 'make kernelversion' does not print some extra version tags
(like 4.19-xxx) so there was a problem with installing CAS on some
kernels. Moved it back to using just 'uname -r'.

Currently Open-CAS uses single queue block interface,
which is removed in kernel in version 5.0.
From this moment on Open-CAS supports only blk-mq,
and single queue is not supported any longer.

While unloading cas_cache module, volume types were deinitialized, although core
pool still wasn't empty. Now this deinitialization can be done after removing
cores from core pool, and before context is freed.

In case of error during cache stop exported object is not being restored after destroying.
This may result in bug in case of calling stop once more.
This commit fixes this issue - exported objects are restored.

Functions and macros dependent on different kernel versions are now generated
before compilation basing on current kernel capabilities instead of hardcoding
them for specific kernels.
