L1: resurrect TCH tap feature
In this new incarnation of our TCH tap feature, we support DL sniffing
in all 3 of FR1, HR1 and EFR, and the new implementation will capture
every 20 ms frame where the old one silently skipped a frame (sent
nothing) during FACCH stealing. The wire interface on RVTMUX changed
slightly, and fc-shell tch record will need to be updated to support
the new version.
TCH UL play or substitution is supported for FR1 and EFR only;
support for HR1 can be added later if needed.
