Max 910a387b0e Move include guard to the top
Having explicit include above the douible-include guard defines is
potential source for hard to track bugs. Let's move it inside the guard
statement.

Jacob Erlbeck 0df80be95e rlc: Add decode_gsm_ra_cap to decode Radio Access Caps
This uses the CSN.1 decoder to fully parse the radio access
capabilities as defined by TS 24.008, 10.5.5.12a.

Jacob Erlbeck c2141c6064 edge: Workaround to fix decoding of EGPRS_AckNack_w_len_t
The presence of the LENGTH field adds an additional offset which
breaks the related M_SERIALIZE in gsm_rlcmac.cpp. In that case,
the Desc in EGPRS_AckNack_t is being cast to EGPRS_AckNack_w_len_t
and then ((EGPRS_AckNack_w_len_t *)Desc)->Desc is filled with the
parsed data, which is a platform dependant number of bytes apart the
real Desc struct.

Remove LENGTH field from EGPRS_AckNack_w_len_t so that the Desc field
is the first field.

Note that this is not a real fix. The rlcmac wireshark dissector
still has the same declaration but doesn't seem to suffer from this
problem.

Ivan Kluchnikov 701d9f83f8 Ported fixes and improvements from Wireshark for RLC/MAC control block decoding. Part 1.
Generic improvements to the csn.1 dissector include:
• Added a flag to the type descriptor structure so that any type can (potentially) flagged as xxx_OR_NULL.  This was specifically needed for UINT_OR_NULL for the ms capabilities struct.
• Changed the CSN_SERIALIZE so that the length of the length field can be specified.
• For CSN_NEXT_EXIST removed the requirement that the next type be CSN_END, to allow truncation of multiple IEs.
• For CSN_LEFT_ALIGNED_VAR_BITMAP corrected the handling of bit_offset.
• Added a new type CSN_PADDING_BITS to make inspection of padding bits more convenient.
• Improved the CSN_RECURSIVE_TARRAY_1 to show the array index.

Improvements to the gsm_rlcmac dissector include:
• Rework the definition of EGPRS Ack/Nack Description so that the length IE (and absence thereof) is handled correctly.
• Added Padding Bits definitions to all PDUs
• Change the Multislot_capability_t and Content_t definitions to allow truncation at any IE
