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.

This needs to be done in caller application context. As part of asynchronous
management API rework, volume_open callback was moved to kernel worker thread
context. To work around this, atomic parameters are now read before cache
attach/load/probe and provided to bottom volume via volume params.
