cef13315d0 Compare properties of a new cache device during cache attach 
New cache device must have all the same properties then the previously
attached one.
Keeping cache properties in cache priv also allows to add new cores to
detached cache instance.

4753374b1b Change CAS_BIO_MAX_VECS value 
Previously when user tried to allocate to big bio he recieved NULL. As the
behavior was changed to `BUG()` passing out of range value is no longer legal.

Limiting the requested bio size to BIO_MAX_PAGES (on the older kernels) or to
BIO_MAX_VECS (on the newer ones) eliminates the problem as the macros represent
the max possible value.

b00de9c940 Use available memory statistic when possible 
Update function returning size of free memory to use available statistic
if that's supported by given kernel. This function is used to check
whether there is enough memory to start cache, and available statistic is
preferred for this check over free statistic, as it does include size of
page cache allocations which can be easily reclaimed by the system.

struct request, which is no longer used by Open CAS.

38bef1f7fe Integrate kmemleak into CAS 
Kmemleak is a tool which allows to detect memory leaks in kernel. It requires
`CONFIG_DEBUG_KMEMLEAK` to be enabled during kernel compilation. Otherwise all
the kmemleak_* functions are NOPs.
