Vadim Yanitskiy 7da06c0609 lapdm: fix SAPI-0/SAPI-3 frame prioritization on DCCH 
According to 3GPP TS 44.005, section 4.2.2 "Priority":

  a) on DCCH, a SAPI=0 frame always has higher priority than SAPI=3;
  b) on ACCH, the priority arrangement is more complex:
    b1) if a SAPI = 3 frame is awaiting transmission, two SAPI=0
        frames shall not be sent in consecutive SACCH frames;
    b2) on the network side (LAPDM_MODE_BTS), it must also be ensured
        that any SAPI=3 frame is followed by at least one SAPI=0 frame;
    b3) a SAPI = 0 frame may be repeated in the next SACCH period
        if the Repeated SACCH is supported (see 3GPP TS 44.006, section 11).

We definitely need to extend our testing coverage to ensure that
we implement b) correctly, but for now let's focus on DCCH:

  a) for DCCH, ensure that SAPI=0 frames preceed SAPI=3 ones;
  b) for ACCH, re-use the existing round-robin implementation.
