DISPATCH-184 - Resolve port name to int when applying configuration
Error in router is caused by a call to getaddrinfo() that uses the 'amqp'
string for port In function qdpn_listener_t *qdpn_listener(qdpn_driver_t
*driver, ...). Same call to getaddrinfo() also appears in qdpn_connector().
There ia a Python class Url.Port() that converts a string port to int and
can handle missing /etc/services. Class used to be in dispatch in proton_future
package, it was recently removed and now it is only in Proton.
As a solution, I had the following ideas:
1. Add a Port type to python/qpid_dispatch_internal/management/schema.py,
do the conversion to int as part of validation.
2. Convert port to int in python/qpid_dispatch_internal/management/agent.py
in ListenerEntity and ConnectorEntity, either in validate, create, or init
method.
3. Catch the error code in qdpn_listener and qdpn_connector and do a if
strcmp(port, "amqp") ... there, Or call into Url.Port() in Python to avoid code
duplication.
I decided to do a PR with the 2nd one.

DISPATCH-184 - Resolve port name to int when applying configuration
Port can be specified either as a string, e.g. 'amqp', or a number. Some
systems do not have 'amqp' in /etc/services. On such systems, port has
to be resolved by dispatch itself.

> If there is no existent record of 'amqp' protocol being 5672/tcp in
> /etc/services, dispatch logs error messages and continue on.
> steps:
> 1. make sure that record 'amqp 5672/tcp' is not present at /etc/services
> 2. run qpid dispatch
> current results:
> Wed Oct 21 16:11:35 2015 DRIVER (error) getaddrinfo(0.0.0.0, amqp): Servname
> not supported for ai_socktype
> and continue.
> expected:
> error message and should stop with error.
> note: this could be added into documentation
