* sverk/packet_size-http/OTP-9389:
  erts: Remove truncation of http packet parsing and return error instead
  honor packet_size for http packet parsing to fix OTP-9389

This is a slight modification of previous commit by Steve Vinoski

For backward compatibility of old users of decode_packet, I think it's enough
to return error instead of keeping the old line truncation behaviour.

Since the API for headers/trailers seem to be very awkward to
work with when using non-blocking io the feature is dropped
for now. See unix_efile.c for more details.
