Vadim Yanitskiy 2c66c15227 fixup mgcp_trunk: increase default number of virtual endpoints
In change I55605ea083565b6950d0820e3f72c50c9dc19ffa, the default
number of endpoints was increased to 512, however the
configuration examples were not updated.

Philipp Maier 41425e9b85 mgcp_vty: add missing VTY commands for E1 trunks
The E1 trunk lacks the VTY commands force-realloc and rtp-accept-all.
However, the function that write the E1 trunk config includes those
commands. Also they would be applicable, so lets add those two commands
also for E1 trunks.

Philipp Maier 31682a3274 mgcp_vty: fix config write for trunk 0
When a trunk 0 is created (which is legal) than it is impossible to
write this trunk back to the config. The reason for this that there is
still a filtering in place from the time where trunk 0 was not allowed.
This filter needs to be extended to filter only virtual trunk 0 but not
E1 trunk 0 out.

The graph "OsmoMGW used with OsmoBSC" shows an RTP and 3GPP AoIP going
to OsmoMSC, this is technically wrong since osmoMSC has no RTP proxy
functionality whatsoever. Since the graph is not so much about OsmoMSC
it makes more sense to label OsmoMSC with "core-network", then it makes
sense and correctly highlights the role of osmo-mgw on the BSS side.

Neels Hofmeyr fbf07f3f69 change timer T2427001 to X2427
libosmo-mgcp-client looks up this timer in a caller provided osmo_tdef
definition. So far, all of our libosmo-mgcp-client callers do not configure
such a timer, so that we always use the default timer value.

We have introduced X timers (negative numbers) to indicate Osmocom specific
timers, and reserve T timers for 3GPP specified ones. So now is still a good
chance to move this timer to the Osmocom X realm.

Remove a comment about this timer at an unrelated place. It is still described
at osmo_mgcpc_ep_alloc().

MDCX may provide a new remote address, which means we may need to update
our announced IP addr and re-bind our local end. This can happen for
instance if MGW initially provided an IPv4 during CRCX ACK, and now MDCX

Pau Espin 8a2a1b22fe mgw: Introduce VTY cmd 'rtp bind-ip-v6' command
This commit allows for fully IPv6 systems to work fine. However, if a
remote endpoint still wants to use IPv4, it will fail since at this
point osmo-mgw still doesn't re-bind the local end of the connection to
an IPv4 after having initially bound it to an IPv6 one. This kind of
scenarios get fixed in next commits.

If "", the default, is passed together with an IPv6 configured
address (ex: "mgw remote-ip ::1") in VTY, socket creation will fail due
to address version mismatch (because getaddrinfo() returns only an IPv4
address in the local result set).
If instead NULL is passed, then 2 entries are returned, one in IPv4 and
one in IPv6, and osmo_sock_init2 is smart enough to take one or another
when passed AF_UNSPEC.
