      This patch eliminates all "wasteful" bflush() calls and · 5119d780
      Roy T. Fielding authored 
      attempts to be as efficient with write()s as possible without making the
code too ugly.

Essentially it makes the chunk header and trailer a part of the output
buffer, and maintains enough state in the BUFF to be able to fix up the
header when it is ready to flush the chunk.  It uses writev() when it's
not efficient for us to buffer a large write -- i.e. a bwrite() of a large
block will first fill the buffer, and chunk that, then if the remaining
part is larger than bufsiz it will be chunked without first copying it to
a buffer.

I added NO_WRITEV which should be defined on platforms that do not have
writev().  They will experience a performance penalty on those large
writes, but that's just too bad.  A keen porter could implement a writev()
that did userland copying to assemble a single write().  For now,
NO_WRITEV is not defined anywhere.
