584ef99143 Change time parameter type in printing 
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).

eef4e49904 Use time since epoch instead of jiffies 
If time is counted in jiffies, machine reboot brokes `dirty for`
statistic for caches loaded at boot. The counter overflows and
`dirty for` shows some huge values.
Cast ticks to unsigned long.
Add necessary header.
Move `env_msleep` to `TIME` subgroup of header.
Move `env_time_after` below time converting functions.

FLush only active core during core removal.
During core removal with `casadm -R` there's a flush triggered.

There was no info about dirty data when core was removed without flush.
Do not destroy exported object while core is inactive.
Perform detach only on active cores.
Skip removing inactive core with command for active cores.
