[dvbapi] SDT parsing optimizations
The SDT filter is now stopped even if no service name or provide name is found. Previously, on FTA or BISS channels, the SDT filter would run forever.
The SDT is now used for getting the tsid and onid of the service (in case we haven't already receive them in the CA PMT).
Duplicate info from the log is removed to keep it clean. The SDT information is only printed once.
Removed some redundant chekcs from the SDT parsing function. They are already done in the caller function.
Added more service types as "tv".
The actual string parsing and supported character sets remained the same (still some eastern character sets are not supported).
