Implement src/daemon.c to provide a high level method to instantiate a
patty server
Changes:
* Refactor src/server.c, src/route.c, src/if.c methods which accept
callsign arguments to use a patty_ax25_addr pointer instead; this
has significantly reduced the number of redundant calls to
patty_ax25_pton()
* Decouple patty_ax25_addr from patty_ax25_if_info types when
creating new interfaces with patty_ax25_if_new(); instead, take a
separate patty_ax25_addr argument
* Split patty_ax25_server_run() into the following methods:
- patty_ax25_server_start()
- patty_ax25_server_stop()
- patty_ax25_server_event_handle()
This is intended to allow possible integration into other event
loops.
* Implement src/daemon.c to allow quick instantiation of a server,
interfaces, and routes, and to encapsulate the setting of
configuration variables; callsigns and interface names are handled
as character strings
* Rename examples/server.c to examples/daemon.c; reimplement in
terms of the patty_daemon code
*
Implement SSID suffix stringes in pton()/ntop() to make it more
straightforward to specify addresses to bind, connect to, or add routes
for
Changes:
* Implement SSID suffix string formatting in patty_ax25_ntop(); drop
the 'ssid' pointer argument
* Implement SSID suffix string parsing in patty_ax25_pton(); drop
the 'ssid' argument
* Change all calls to patty_ax25_ntop() and patty_ax25_pton() to use
their new calling convention
Significantly simplify dictionaries so that dictionary keys are always
uint32_t; this number can be an arbitrary integer, be it a file
descriptor, for instance, or a hashed value
