util: Add helper to write() all of a buffer
write(2) might not write all the data it is given. Add a write_all_buf()
helper to keep calling it until all the given data is written, or we get an
error.
Currently we use write_remainder() to do this operation in pcap_frame().
That's a little awkward since it requires constructing an iovec, and future
changes we want to make to write_remainder() will be easier in terms of
this single buffer helper.
