* XXX - [3] 11.4.1 - Table 11.1 ([3] is ETSI TS 101 376-4-8

* "Extended Immediate Assignment" and "Immediate Assignment Type 2"
* and has 0x3b meaning both "Immediate Asignment Reject Type 2"
* and "Extended Imm. Assignment Reject".
*
* [3] makes some references to [1] ([1] is ETSI TS 101 376-4-8
* V1.3.1, which is GMR-1 04.008, not to be confused with GMR-1
* 3G 44.008), saying some messages are the same as in GMR-1
* 04.008. [1]:
*
* says, in 10.1.18.2, that "Extended immediate assignment"
* "is sent on the main signalling link by the network to
* the MES in response to an EXTENDED CHANNEL REQUEST message
* by the MES";
*
* says, in 10.1.20.2, that "Immediate assignment reject type 2"
* "may be sent to the MES by the network on the CCCH to indicate
* that no channel is available for assignment or that the MES
* cannot be allowed access";
*
* says, in 10.1.20.3, that "Extended immediate assignment
* reject" "message is sent by the network on the DCCH to
* indicate that no channel is available for assignment or
* that the MES cannot be allowed access";
*
* does not mention "Immediate assignment type 2" anywhere
* that I can see.
*
* [3]:
*
* says, in 10.1.18.2, that "Extended immediate assignment
* (A/Gb mode only)" is "Same as clause 10.1.18.2 of
* GMR-1 04.008";
*
* says, in 10.1.18.3, that "Intermediate assignment Type
* 2 (A/Gb mode only)" "is sent on the CCCH by the network
* to the MES to change the channel configuration to a
* dedicated configuration while staying in the same cell";
*
* says, in 10.1.20.2, that "Immediate assignment reject
* type 2" is "Same as clause 10.1.20.2 of GMR-1 04.008";
*
* says, in 10.1.20.3, that "Extended immediate assignment
* reject" is "Same as clause 10.1.20.3 of GMR-1 04.008".
*
* This is currently handled by ORing 0x100 into the values
* for the DCCH, and, in gmr1_get_msg_rr_params(), if the dcch
* parameter is set (which it is if called from gmr1_get_msg_params()
* in packet-gmr1_common.c), 0x100 is ORed into the value
* passed to try_val_to_str_idx(). If that returns NULL, or
* isn't called in the first placee, it calls try_val_to_str_idx()
* without ORing in 0x100.
*
* So that's why a 1-byte field has, in a value_string used with
* it, two values that don't fit into 1 byte.
*
* It Would Be Nice if this could be done in a somewhat less
* hackish and opaque fashion.
