Title:
  Compression errors with zlib 1.2.11

Status in AirDC++:
  Fix Released
Status in ApexDC++:
  Fix Committed
Status in DC++:
  Fix Released

Bug description:
  After updating zlib to version 1.2.10, transfers randomly fail because
  of compression errors. Such errors happening on uploader's side won't
  reported anywhere, the upload just gets disconnected.

  Based on some debugging with AirDC++, the actual location where the
  error happens in zlib is
  https://github.com/madler/zlib/blob/master/deflate.c#L595

  I'm not sure whether that's a bug in zlib or something intended as
  there are also breaking changes in version 1.2.10:
  https://github.com/madler/zlib/issues/190 (avail_out is not originally
  zero when the call is made)

  Setting compression level at
  https://sourceforge.net/p/dcplusplus/code/ci/default/tree/dcpp/ZUtils.cpp#l59
  to a non-zero value seems to help with avoiding the issue.
