Adding new feature - Kcov



Hello,
   I have attached a patch which adds the Kernel Code Coverage(KCov)
to the NetBSD kernel.
This is one of the foundational steps to get Syzkaller (Kernel Fuzzer)
fully functional on NetBSD.

The option can be enabled by uncommenting the following lines in amd64/GENERIC
makeoptions KCOV=1
options KCOV

The patch also contains a man page and a ATF test for the same.

Please let me know if there are any issues with the same.
