Ian Lepore f4d281428f Add a new flag, SBUF_INCLUDENUL, and new get/set/clear functions for flags.
The SBUF_INCLUDENUL flag causes the nulterm byte at the end of the string
to be counted in the length of the data.  If copying the data using the
sbuf_data() and sbuf_len() functions, or if writing it automatically with
a drain function, the net effect is that the nulterm byte is copied along
with the rest of the data.
