79d1393e74 Implement patty_ax25_addr_copy() 
Implement patty_ax25_addr_copy() as a means to copy a patty_ax25_addr
object from one location in memory to another, ensuring that the SSID
field only contains at minimum the station identifier (0-15) and the
reserved bits 0x60

a4518a839a Implement better modulo-128 I and S frame support 
Changes:

    * Split patty_ax25_frame_decode() into the following:

      - patty_ax25_frame_decode_address()
      - patty_ax25_frame_decode_control()

      This allows for look up an established socket for a given address
      pair, to determine if an SABME session is in progress,
      necessitating modulo-128 control decoding

    * Decode I and S N(R), N(S) sequence numbers, poll/final
      bits properly in both modulo-8 and modulo-128 mode

    * Perform better frame control validation

    * Implement the following functions in src/sock.c:

      - patty_ax25_sock_send_rr()
      - patty_ax25_sock_send_rnr()
      - patty_ax25_sock_send_rej()
      - patty_ax25_sock_send_srej()

      Corresponding functions have been removed from src/server.c

    * Implement better functions in src/sock.c for encoding frame
      control, with send/receive sequences associated with the socket,
      with modulo-128 encoding for SABME sessions

Other changes:

    * Move or delete macros from include/patty/ax25/macros.h into
      include/patty/ax25.h and include/patty/ax25/frame.h

    * Move definitions from include/patty/ax25/proto.h to header file
      include/patty/ax25.h

    * Perform better bounds checking while decoding frames

    * Improve frame control printing in src/print.c; display frame
      type names, N(R), (NS) sequence numbers, and poll/final bits
