Add the following enhancements to the UMTS RLC dissector
(as specified in 3GPP 25.322 v9.2.0):
- UDP framing protocol to allow dissection of RLC PDUs over UDP (like what is
done for LTE MAC/RLC/PDCP protocols)
- 15 bits Length Indicator support (both with variable and fixed LI size)
- Poll type SUFI
- enhanced dissection of LIST, Relative List and Bitmap SUFI
- dissection of Reset and Reset Ack Control PDU
- an option to decode RLC headers only
- an option to skip SDU reassembly

Bug 5494 - FP-Hint: Display correct DCH-ID value
In FP-Hint, DCH-IDs are stored as a 5-bit value. While a 5-bit value can
hold values from 0..31, DCH-IDs in the NBAP, RNSAP and RRC protocols
have values from 1..32.
This patch adds 1 to the DCH-ID in FP-Hint in order to display the
correct DCH-ID value in the protcol tree.

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.

New protocols: UMTS RLC (ETSI TS 125 322), UMTS MAC (ETSI TS 125 321).
This does not currently compile cleanly but checking it in to be worked on.
