Merge branch 'paraglob' of https://github.com/ZekeMedley/zeek

* 'paraglob' of https://github.com/ZekeMedley/zeek:
  Add leak test to paraglob.
  Catch paraglob serialization errors in DoClone.
  Update paraglob serialization.
  Stop execution on paraglob error.
  Update paraglob submodule
  Change C++11 detection in paraglob.
  Make paraglob serializable and copyable.
  Initial paraglob integration.

I made a bunch of small changes:
 * paraglob now deals better with \0 characters
 * I rolled back the changes to Binary Serialization format,
 * there were some small formatting issue
 * the error output was slightly unsafe
 * build_unique is now in util.h.

and perhaps a few more small things.
