#1375 closed patch (fixed)
Fix elementary CA descriptors in new siparser.cpp

Description
Inside the HandlePMT function the new code for the elementary level CA descriptors will only insert the first found by the 'Find'. Foxtel Australia has 3 supported conditional access systems which requires all 3 to be inserted.
This patch implements the same list search functionality as exists at program level.

Just for more information this is a PMT decode of one of these channels:

(In [9118]) Fixes #1375, References #1035. Allow each A/V stream to use multiple Conditional Access methods.
Apparently this is used in Australia. I'm not sure if they use different methods for the video, audio, and data streams, or if they just list all the supported methods and hope one is sticks. Multiple CA methods per PMT was already supported.
