e9608da9c8 From Pascal Quantin: 
Show SDU lengths for UM PDUs.
Also, if the logged pduLength is < the real RLC PDU length, show that the length of the last segment is unknown.

- set extent of headers item properly
- show in the info column what the data would look like, based upon reported length and segment offsets

126aa85393 Convert proto_tree_add_item() 'encoding' arg for field types FT_STRING, FT_STRINGZ, FT_UINT_STRING as follows: 
1. If there's no character encoding (ENC_ASCII, ...) specified
    then use ENC_ASCII.
 2. For all but FT_UINT_STRING, always use ENC_NA
    (replacing any existing True/1/FALSE/0
    /ENC_BIG_ENDIAN/ENC_LITTLE_ENDIAN).

4e57694d4a Convert 'encoding' parameter of certain proto_tree_add_item() calls in non-autogenerated epan/dissectors: 
Specifically:  Replace FALSE|0 and TRUE|1 by ENC_BIG_ENDIAN|ENC_LITTLE_ENDIAN as
 the encoding parameter for proto_tree_add_item() calls which directly reference
 an item in hf[] which has a type of:
    FT_UINT8
    FT_UINT16
    FT_UINT24
    FT_UINT32
    FT_UINT64
    FT_INT8

   FT_OID

ca126bace5 Don't attach sequence analysis results to control/data PDUs when not appropriate. The problem is that I use the frame number in the result hash table - I may end up adding more info (e.g. channel, SN) to further avoid attaching reports to wrong PDUs.
