1f979f630b Adding synchronization primitives destroyers 
Environment should provide calls for destroying primitives (i.e. env_mutex_destroy()) and OCF should call these functions in its cleanup paths.

1373471af7 Introduce OCF_CMPL_RET() macro 
This simplifies cases when we want to call completion callback
and immediately return from void-returning function, by allowing
to explicitly express programmers intent. That way we can avoid
cases when return statement is missing by mistake (this patch
fixes at least one bug related to this).

c5a80cc488 Use env_secure_(alloc/free) macro for metadata allocations 
Adapter can opt to take additional steps to securely allocate
memory used by OCF to store cache metadata. Typically this would
involve mlocking pages and zeroing memory before deallocation.

Memory allocated using secure_alloc is not expected to be zeroed
or physically continous.
