When the first test device was added (vivi.c), there were just
one file. I was too lazy on that time to create a separate
directory just for it, so I kept it together with platform.
Now, we have vivid, vicodec, vim2m and vimc. Also, a new
virtual driver has been prepared to support DVB API.
So, it is time to solve this mess, by placing test stuff
on a separate directory.
It should be noticed that we also have some skeleton drivers
(for V4L and for DVB). For now, we'll keep them separate,
as they're not really test drivers, but instead, just
examples. The DVB frontend ones will likely be part of a new DVB
test driver. By that time, it should make sense to move them
here as well.

The implementation of strscpy() is more robust and safer.
That's now the recommended way to copy NUL terminated strings.

time_to_tm() takes a time_t value that overflows in 2038 on 32-bit
systems. time64_to_tm() doesn't have this problem, so let's use that in
combination with ktime_get_real_seconds() to read a 64-bit time
value.

The smatch utility got really confused about the grp % 22 code. Rewrote
it so it now understands that there really isn't a buffer overwrite.

This adds radio receiver and transmitter support. Part of that is common
to both and so is placed in the radio-common source.
These drivers also support RDS. In order to generate valid RDS data a
simple RDS generator is implemented in rds-gen.
