MSC_ConnectionHandler: split up as_media into separate altsteps 

as_media() tests both, IPACC/RSL media handling and MGCP media
handling. These two domains are technically quite separate, which
means we can split them up into two separate altsteps in order
to increase readability of the code.

- Split as_media() into as_Media_ipacc() and as_Media_mgw()
