again when downloading files over FTP using ASCII and it turns out that the
  final size of the file is not the same as the initial size the server
  reported. This is very common since servers don't take the newline
  conversions into account.

Add some debug messages to see what's going on with valgrind logs.

  to be due to two different flaws now fixed. Gil's excellent recipe helped me
  nail this.

much as possible in one go, as long as it doesn't block and hasn't reached the
end of the state machine.
This avoids spurious -1 returns from curl_multi_fdset() simply because
previously it would return from this function without anything in EWOUDLBLOCK
and thus basically it wasn't actually waiting for anything!!

state, we return CURLM_CALL_MULTI_PERFORM unconditionally then so that we
can act faster like in the case the protocol-specific connect doesn't block
on anything and we can just persue on the next action immediately. It also
then avoids a case where curl_multi_fdset() would return -1.

  present in the tests/data/Makefile.am and outputs a notice message on the

  included in release archives and forgetting to add files there is a common
  mistake. This is an attempt to make it harder to forget.
