Unfortunately, the autobuilder is using an old version of OSX, and
cannot use ghc newer than the one in lts-13.11. Newer ghc versions use a
libc symbol that is not available.
Since the main stack.yaml has been updated to a newer lts, and just
substituting in lts-13.11 no longer works due to other dependency
issues, it's simplest to use a separate one for the OSX build.
Hopefully this is temporary, and the autobuilder gets updated.
Fixes reversion in 8.20200617 that made annex.pidlock being enabled result
in some commands stalling, particularly those needing to autoinit.
Renamed runsGitAnnexChildProcess to make clearer where it should be
used.
Arguably, it would be better to have a way to make any process git-annex
runs have the env var set. But then it would need to take the pid lock
when running any and all processes, and that would be a problem when
git-annex runs two processes concurrently. So, I'm left doing it ad-hoc
in places where git-annex really does run a child process, directly
or indirectly via a particular git command.
addurl: Fix reversion in 7.20190322 that made --file not be honored when
youtube-dl was used to download media.
8758f9c561 was on the right track, but missed that | otherwise prevented
the code it added from being used.
Also, refactored out a common function.

I'm sure this used to work, but somewhere along the line something or
things (getCost and getAvailability I think, probably others)
started catching the exception and not displaying it. So, show warnings.
