mgcp: Add VTY commands to block endpoints instead of having this hardcoded

Instead of assuming which endpoints are blocked there is now a VTY
command to block those. Clean up the init of the trunks, the only difference
between Virtual and E1 is in the way to calculate the start port.

Reduce the number of endpoints to 32, 31 is the last one that can be
used on the E1 trunk, otherwise we move into TS 0 of the following trunk.
