[Bug 19861] Wine should warn when ulimit -n needs raising

I feel strongly that we should print a single warning to the winediag channel
in this case, as the patch does, so that the user can complain to whoever
packaged his Wine, or raise the limit on his own in the meantime.

Wine seems to use two fd's per file handle in some situations as a result
of a recent commit, and this causes some real applications to explode
even on Ubuntu, where the fd limit is already set fairly high.  The
failures are mysterious and annoying enough that they merit a +winediag
message.

The exact message should probably be more generic, though, since not all
systems have the same mechanism for raising the limit.
