d4e9304fd2 Add a way for configuration protocol (e.g. RRC) to configure MAC-> RLC mappings, and add a preference to use this or the static UAT. 
API is not yet called by RRC.

50e1634f4c Modify proto_tree_add_bytes_format() and proto_tree_add_bytes_format_value() 
so that if the start_ptr is NULL the bytes are extracted from the given TVB
using the given offset and length.

Replace a bunch of:

proto_tree_add_bytes_format*(tree, hf, tvb, offset, length, tvb_get_ptr(tvb, offset, length), [...])

with:

proto_tree_add_bytes_format*(tree, hf, tvb, offset, length, NULL, [...])

8d32d2066a There's no need to pass the result of tvb_get_ptr() as the 'value' in 
proto_tree_add_*(): just use proto_tree_add_item().

Replace some tvb_get_ptr()s with tvb_get_ephemeral_string() or
tvb_get_const_stringz().

Use tvb_memeql() & tvb_memcmp().

c642bae035 From Pascal Quantin: 
The decoder expects to do not have any extra byte after the RAR bodies.

But according to 3GPP 36.321 8.8.0 chapter 6.1.5, the eNodeB is allowed to put padding at the end of the RAR PDU:

" A MAC PDU consists of a MAC header and zero or more MAC Random Access Responses (MAC RAR) and optionally padding as described in figure 6.1.5-4.
[...]

Padding may occur after the last MAC RAR. Presence and length of padding is implicit based on TB size, size of MAC header and number of RARs."
