deflatePrime() inserts bits in the deflate output stream. The intent
is that this function is used to start off the deflate output with the
bits leftover from a previous deflate stream when appending to it. As such,
this function can only be used for raw deflate, and must be used before the
first deflate() call after a deflateInit2() or deflateReset(). bits must be
less than or equal to 16, and that many of the least significant bits of
value will be inserted in the output.
deflatePrime returns Z_OK if success, or Z_STREAM_ERROR if the source
stream state was inconsistent.
