Frédéric Wang 675225dd5a Bug 1574749 - Remove support for nonzero unitless lengths. r=emilio
See https://github.com/mathml-refresh/mathml/issues/24
and https://groups.google.com/forum/#!topic/mozilla.dev.platform/-yV6wb3klSA

This commit introduces a new preference option
mathml.nonzero_unitless_lengths.disabled to disable MathML nonzero unitless
values like "5" for 500%. MathML nonzero unitless are now disabled by default
but it could be easily enabled again later if we decide otherwise.

* test_bug553917.html is updated to check that these values now cause an error
  message to be logged into the console rather than a deprecated warning
  when nonzero unitless lengths are disabled.
  Additionally, the test checking invalid double dots "2..0" is updated not
  to use unitless syntax.
* The old test 355548-3.xml checks support for mathsize names and also uses
  several features that are going to be deprecated. So it is just run with
  the proper preference adjustment.
* mfrac-linethickness-2.xhtml and number-size-1.xhtml check support for
  unitless lengths so they are now run with that support enabled.
* WPT tests frac-linethickness-001.html and lengths-1.html are executed with
  the some MathML features disabled in order to make them pass.
  We get more assertion passing for the "Legacy numbers" test of
  lengths-2.html ; however there are still some issues to address
  (see bug 1574751).
