Changes:
* Implement src/conf.c, patty_conf_read(), to read a configuration
file to support a OpenBSD-style configuration file format
* Implement bin/pattyd.c to use patty_conf_read() to read a
configuration file and apply its settings to a patty_daemon
object as it is read; also implement a --standalone|-s flag to
allow the user to start a patty server without having to write
a configuration file
* Refactor patty_daemon_if_add() to accept a patty_ax25_if object;
this is necessary as bin/pattyd.c needs to be able to validate
the addresses given in a configuration file 'if' statement
* Refactor patty_ax25_server_new() to no longer accept a client
socket path; instead, patty_ax25_server_start() now accepts the
client socket path
* Remove the client socket 'path' member from patty_ax25_server in
src/server.c
* Refactor patty_kiss_tnc_new() to accept only one argument, a
patty_kiss_tnc_info object containing flags and settings needed
to open a device, use an existing file descriptor, or change
termios settings as appropriate
* Remove patty_kiss_tnc_new_fd(), as its functionality now exists
in patty_kiss_tnc_new() itself
* Add a 'flags' field to patty_kiss_tnc_info; use this bit field
to determine whether a path or file descriptor is provided by
the caller
* Make patty_ax25_if_new() accept an interface name argument, as
names are explicitly required when declaring new interfaces in
configuration files
* Make patty_kiss_tnc_new() able to accept /dev/ptmx as a device
name, regardless of whether this character device exists on a
given platform; when provided, a pseudo TTY pair is allocated
with openpty()
* Refactor examples/ax25dump.c to use the new patty_kiss_tnc_new()
calling convention
* Refactor examples/decode.c to use the new patty_kiss_tnc_new()
calling convention
* Remove examples/daemon.c in favor of bin/pattyd.c
* Rename examples/patty.conf to examples/pattyd.conf; modify to
provide values which would actually function
