OML link state is available via vty ("sh bts 0" command) and
ctrl ("oml-connection-state" RO variable).
When showing OML link state, take into consideration RSL link state as
well: if OML is up but RSL is missing show it as degraded.
That's implemented via BTS model-specific functions (currently Sysmo- and
Nano- BTS only)

This is the first step in creating this repository from the legacy openbsc.git.
Like all other Osmocom repositories, keep the autoconf and automake files in
the repository root. openbsc.git has been the sole exception, which ends now.
