   Modified Files:   
   	src/sbbs3/main.cpp   
   Log Message:   
   Add and improve log messages (warnings, errors) in input_thread()   
      
   ... mainly to help understand (still a mystery) how the first check of   
   the inbuf free space could pass (there's at least one byte available), but   
   the second check (after recv()) fail and the "INPUT BUFFER FULL" message gets   
   logged - that doesn't seem possible unless there's some other thread stuffing   
   chars into the inbuf (and that shouldn't be happening with the exception of   
   node spying).   
      
   While investigating this mystery, I saw there missing node numbers and other   
   helpful data (e.g. the number of bytes received to that point) from some of   
   the log messages. And in some SSH error conditions, nothing would be logged   
   though the input_thread's loop would terminate (break), so added some log   
   messages for "Operation complete" and "Timeout" which had explicit handlers   
   with no log output.   
      
   Increase the received byte counter from 32 to 64-bits.   
      
   Stop using the 'rd' varible for multiple purposes, improving readability.
