The two callback functions policy_cb and change_cb are essentially dead
code. They also make the code more difficult to read and understand.
Lets remove them.

At the moment the MGCP request handling and message parsing is not
clearly separated. The function mgcp_parse_header() in mgcp_msg.c is
also responsible for resolving an endpoint. This leads to unclear layer
separation. We eventually end up in a situation where we can not execute
any request handler without beeing able to resolve an endpoint, however
this is necessary if we want to implement wildcarded DLCX resquests.
In the current situation a wildcarded DLCX is not possible to implement
as we always have to resolve a an to get to the trunk which we need to
iterate. However, we just can't resolve a free endpoint in a situation
where all endpoints on te trunk are in use.
We have to refactor the request handler so that the parsing in mgcp_msg
only extracts us the endpoint name. The resolving is then done in
mgcp_handle_message() in mgcp_protocol.c. Then we are able to decide
what to do if we are unable to resolve an endpoint but still be able to
resolve the trunk.
This patch does not change the behaviour of osmo-mgw yet, but it lays
the foundation for request handler implementations that can still
perform useful actions if no endpoint but a trunk has been resolved. A
wilcarded DLCX is such a case. It does not need an endpoint, just the
trunk.

The function mgcp_rtp_end_config() takes an mgcp_endpoint as
parameter. The header file does not declare the mgcp_endp struct
and it also does not include mgcp_endp.h because that also would
cause problems. Since the endp parameter in mgcp_rtp_end_config()
is only a pointer we can simply forward declare it.
This patch will currently not change anythig, but it will prevent
compiler warnings when we remove the endp pointer from
struct mgcp_parse_data in a follow up patch

The file mgcp_internal.h still contains mostly definitions and types
that are relevant for mgcp_network.c and mgcp_protocol.c. Lets give
the network and protocol module its own header files, also move stuff
that does not relate to protocol and network to the appropiate places.
