The remaining problem is that proxy_lb_workers() only gives a good value when
the config file has been parsed (can't be used in preconfig().

Note the mod_scoreboard.c just uses the actual scoreboard "shared" area
for the workers.

configuration as well as a (limited) dynamic configuration.

  Alas, it was not to be.  Deprecate mod_aspdotnet, and certainly don't
  introduce these docs into the next release or consider for backport.

Revert r422298, because it introduces GNU Make specific extensions to the Makefile, and should be replaced by doing the work inside configure, instead of the Makefile.in.

  error (either in the lower filter chain or during a libz operation). We need
  to call deflateEnd as it is very likely that this filter is never called
  again to ensures that libz's internal structures get cleaned properly.

  structures of libz never got flushed as ctx->stream.avail_in is always zero
  here. As the EOS and the FLUSH bucket case use the same code for flushing
  libz's internal buffers move this code to the new function flush_zlib_buffer.
