[PATCH 0/3] ci: upgrade to the latest Azure Pipelines agent pools

At least the Windows agents we use will go away on March 23rd, 2020 [https://devblogs.microsoft.com/devops/removing-older-images-in-azure-pipelines-hosted-pools/] , in favor of newer, faster, better ones. We might just as well use the latter already long before the cut-off date.

While at it, let's also update to a newer macOS pool. This necessitates two distinct fixes, though:

 * Our ci/ scripts were ill-prepared to deal with System Integrity
   Protection [https://support.apple.com/en-us/HT204899]. This resulted in
   the p4d -V call seemingly "hanging" (Narrator's voice: it did not "hang",
   it actually opened a GUI dialog to ask the user whether it was okay to
   execute this quarantined executable).
   
   
 * Apparently nobody ever bothered running the Apache2-based tests (t5616,
   t5702 and t5703, probably more) on macOS. I say that because they don't
   work, over-relying on GNU-specific behavior of sed. I rewrote those sed 
   calls to use Perl instead.

  t/lib-httpd: avoid using BSD's sed
  ci: prevent `perforce` from being quarantined
