add support for GNU/kFreeBSD

It changes some "defined (__FreeBSD__)" into "defined (__FreeBSD_kernel__)"
and "__FreeBSD_version" into "__FreeBSD_kernel_version".

The changes are performed on places, where feature of kernel is tested. On
some other places, feature of userland/libc is tested, on them "defined
(__FreeBSD__)" remains.

As proposed, include/configure.h cause __FreeBSD_kernel__ be defined if
__FreeBSD__ is defined.
