Patch for the AX.25 module to provide support for
the has-been-repeated flag in received frames.

This flag is set using the high bit (0x80) of the SSID byte for each
call sign in the path. The patch attached here checks for this flag
when parsing incoming packets, and (per suggestion from Francesco)
stores the flag bit-mapped to a single byte added to the AX25 context.
