OSCam svn11520 Emu-r796

by @audi06_19

Changeset [11520]
-Added support for a higher number of demux devices in CA PMT
-Modern enigma2 boxes with FCB tuners can have many demux devices,
-so a new CA PMT descriptor that allows up to 128 demuxes (descriptor tag 0x86) is now supported.
-Also, the get_demux_options() function is completely re-written,
-so it doesn't care for the order of descriptors inside the CA PMT message.
