1. When generating cas_blk_rq_append_bio, check whether a
version with double pointer compiles successfully. This
is a better criteria than the version with single pointer
since the latter may compile successfully regardless of
kernel blk_rq_append_bio prototype.
2. Always provide single pointer to cas_blk_rq_append_bio
macro - its up to cas_blk_rq_append_bio implementation to
decide whether extra level of indirection is needed.
This fixes compilation with kernel 4.14.98.

To prevent using macros before they are defined, enfoce calling them in an
appropriate order.

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.
