b5ed9e9b61 Fix patty_kiss_tnc_recv() reads less than bufsz 
Fix issues with patty_kiss_tnc_recv() when read() calls return less than
the allocated buffer size

d266058ad4 Fix patty_kiss_tnc_recv() issues 
Fix patty_kiss_tnc_recv() issues with small buffers (~330 bytes) by
more properly detecting EOF being the condition at which the current
decoder offset in the buffer is equal to the last buffer read size; the
offset can never be the number of bytes read, and the initial read
length is -1, so early EOF conditions are avoided

750ab452d2 Refactor patty_kiss_tnc_recv() 
Refactor patty_kiss_tnc_recv() to always read a fixed number of bytes
into a circular buffer

Other changes:

    * Avoid needing memmove() per packet processed

    * Allow processing packets larger than the internal read buffer

d44889121e Do not decode KISS frames into internal buffer 
Changes:

    * Modify patty_kiss_tnc_recv() to accept a pointer to a read buffer,
      and a maximum length argument, to receive one packet

    * Modify src/decode.c to use the new patty_kiss_tnc_recv() calling
      form

ede262397b Refactor patty_kiss_tnc_recv() 
Refactor patty_kiss_tnc_recv() to be much more compact and correct;
