#10784: match EIT to channels without looking at ONID or TSID in dtv_multiplex

--------------------------------------+-------------------------
This patch allows the EITScanner to find the right channel even if
* the broadcaster messed up their feed (e.g. feeding DVB-C from DVB-S with
mashed up multiplexes. The PMT/SDT gets properly rewritten with new
ONID/TSID but the EIT is copied unchanged)
* the channel scanner couldn't figure out ONID/TSID

Use cases to test
* passive scan within a transport (worked very well)
* active scan within a transport (I need to look at it again)
* any scan across transports (I can't test it due to no access to DVB-S)

Use cases that do not work due to missing glue code
* EIT from IPTV, etc.

Comment (by dekarl@…):

I've been running with the patch in production and it worked so well, in
active scan, I forgot to put the ONID/TSID back in.

Still to test DVB with EIT(other) (common on DVB-S) but that just uses the
old code path which worked before.

Implement fuzzy matching of channels for EIT.

Refs #10784. First try to find the channel using the full
NetID, TransportID, ServiceID. If that fails try again using
just NetID, ServiceID.

We can extend this further using some of the other ideas in
this ticket.
