rlcmac: Introduce MS Radio Access Capabilities 2 to fix related spare bits
There's two variants for the Ms Radio Access Capabilities.
* The usual encoding with spare bits (usually to fill up to octet boundary)
as defined in TS 24.008 Table 10.5.146
And there's too:
* MS Radio Access Capabilities 2 IE from TS44.060 section 12.30, which is
the same but removing all spare bits, and which is used in messages like
Packet Resource Request and Additional MS RAC messages.
The later is used basically for messages having extra IEs after the MS
Radio Access capabilities IE, since they are encoded immediatelly
afterwards.
So this patch does:
* Adds the expected spare bits (M_PADDING) to MS_Radio_Access_capability_t
* Creates a new MS_Radio_Access_capability2_t without padding
* Updates code to use the new "2" version where needed.
The new MS_Radio_Access_capability_t with padding is disabled since it's
not used in wirehsark because it's using an ad-hoc decoder for that TS
24.008 IE: see packet-gsm_a_gm.c de_gmm_ms_radio_acc_cap()
