DVB Help update
descrambler: improve the ECM handling

- for constcw (CAID 2600) do not expect any key change
- when the stream is broken, try to issue new ECM request

Note: The TS data might be wrong (which may cause the ECM late
situations). This patch tries to ask for new ECM to be sure
that the keys are correct. The constcw specific code is just
an optimization. The new ECM request is not required for it.
add ERRNO_AGAIN() macro to check the interrupted / no data states correctly
muxers: handle ECONNRESET errno as end-of-stream
epggrab: test code for only tuning muxes that require it
epggrab: fix the missing variable initialization and NULL dereference
epggrab: eit - fix the shutdown sequence
