RE: sb_sasl_write doesn't handle partial writes (ITS#2211)

I see what you're getting at, but I don't see why there is still a problem.
If ber_pvt_sb_do_write doesn't write the entire buffer in the first call, it
will try to flush in a subsequent call. There will always be a subsequent
call, because eventually the search result code must be written out. The code
in 2.1.8 has already been tested successfully with very large search entries.
