epan/dissectors/packet-umts_fp.c
* Added mac subdissector (MAC) call to HSDSCH TYPE2 frames

epan/dissectors/packet-umts_mac.c
* Added support for HSDSCH TYPE2 frames by means of
        not nibble-shifting (4 bits) the SDU if MAC-ehs is used

epan/dissectors/packet-rlc.c
* Added support for "Use special value of the HE field" (3gpp 25.332-7a0 
9.2.2.7) commonly used for Release 7 HSDPA.
        REMARK: although the specification mandates that the
        special value is only allowed when activated by higher
        layers (RRC), it is interpreted unconditionally. We assume
        this is OK, because a different use in future specifications
        is very unlikely.

epan/dissectors/packet-fp_hint.c
* Added decoding of MAC-ehs indicator for HSDSCH frames
* Bumped fpi->release from 6 to 7 to enable proper
        HSDSCH TYPE2 frame decoding in the UTMS MAC parser.
        In general, this appears not to affect decoding
        of (conformant) FP frames of pevious releases.
