added new Request REQ_DISABLE_PID_FILTER

[rga-medix]

Current workflow is:

• Connect to control and transfer sockets
• REQ_TUNE (req=2)
• REQ_GET_STATUS (req=3) polling, till Lock is confirmed
• REQ_SET_PIDS (req=4) with all PIDs (must be known beforehand from somewhere..) to be able to parse PMT
• REQ_SET_PIDS (req=4) use obtained PMT data to move from some sort of MPTS to some sort of SPTS
• read the modified stream from transfer socket

issue: this only works if the PIDs are known. To parse PMT data we need passFullTsStream to be trueotherwise reset() in DvbDemux would always filter to PID 0. Setting passFullTsStream was not exposed as a Request, only active in debug view of the project.

I have added a new Request named REQ_DISABLE_PID_FILTER at the end of the enum to keep the existing Ordinal numbering stable.

Now we can use this workflow:

• Connect to control and transfer sockets
• REQ_DISABLE_PID_FILTER (req=6) to allow full MPTS
• REQ_TUNE (req=2)
• REQ_GET_STATUS (req=3) polling, till Lock is confirmed
• parse PMT data from the MPTS stream
• REQ_SET_PIDS (req=4) use obtained PMT data to move from real MPTS to some sort of SPTS
• read the modified stream from transfer socket
