DVB card setup: multirec defaults to on upon entering Recording Options page

[Nick Morrott <knowledgejunkie (at) gmail (dot) com>]

Using the same configuration as reported in #8726.

When configuring a new DVB card, multirec is not enabled by default. If a user does not open the recording options page to change settings such as active EIT or on-demand card usage, a single non-multirec DVB-T tuner is configured.

However, if the user does open the recording options page to change any of its settings, multirec becomes selected as a side-effect (defaults to 2 virtual tuners). This means that in order to only change any of the other settings on the options page, the user must also reset the multirec option to a single recording to preserve a single tuner configuration. Changing any non-multirec setting and accepting the changes enables multirec when returning to the main card setup page.

This may be considered a feature request, but I would suggest that the recording options page defaults to a single recording when mythtv-setup undergoes its MythUI overhall, and the user must explicitly enable multirec if desired.

(In [25629]) Fixes #8736. This makes the multirec behaviour consistent whether you enter Recording Options or not.

This always creates one virtual card for DVB/HDHR unless the user explicitly changes this in the Recording Options screen.

The number of cards created is now controlled kDefaultMultirecCount, which is set to 2. If we want to change it to 1 or 3 or some other number in the future it is now just a policy decision as it is trivial to do.
