everything ends up in the same place so I didn't see this ticket...

extend unit test to avoid a regression (CRID without IMI)
Don't show the "Preset tuner to channel" option in mythtv-setup, if the
input type is not a tuner.

Fixes #11761
fix more DVR service issues.

I could have sworn I'd tested this all better, but thinking back, I
think I mainly focused on recurring rules with UpdateRecordSchedule()
and assumed AddRecordSchedule() also worked since they are almost
identical.

Fixes #11753
Disable database logging by default.

It can be re-enabled using --enable-dblog

Until we actually start using this data somewhere there is not much
point in storing it. Since it's already known that writing to the
database can affect I/O performance, especially where drives are
shared with recordings, this could potentially even cause a positive
feedback loop. The I/O starvation causes the backend to start logging
slow read/write warnings, which in turn increase the writes to the
database exacerbating the problems.

The same problem is also true, to a greater or lesser extent with file
based logging but we actually need the file logs so there isn't much
we can do there.
