Don't remove inactive core if it has dirt cache lines assigned unless `force`
flag is specified.

Type of `dirty_for` in structs needs to be unified.
Values stored in these fields (both in cache and core info structs)
are unsigned 64-bits ints but `dirty_for`s were unsigned 32-bits ints
(vide changes in OCF).

On some systems, e.g. Ubuntu, the order of linking `math` library is
important and when linking is done too early, openCAS making fails.

If an underflowed float number was casted to an int explicitly, it's value was
rounded to a lower value.
Using `round()` function ensures that the number will be always rounded to a
nearest integer.

Force option is used to enforce metadata erasure despite
dirty data, metadata mistmatch and/or dirty shutdown.

Kernel adapter now returns is_cache_device=1 and newly added
metadata_compatible=0 in case of metadata detected with
differing version (instead of is_cache_device = 0).
This allows zero-superblock command to recognize old
cache instance and clear it.
casadm --script --check-cache-device still returns 'Is cache'='no'
in this case, as this layer only cares about metadata in current
version to be able to detect dirty datas tatus.

This check covers the previous case (cache started) as well as
other potential incorrect usages of the command. Also now
the check is made exactly at the moment of opening the
device to write to.

Not every usage of `set_device_path()` needs to print message.
Sometimes it's internal operation and can contain misleading info.
