Allow running tests on multiple trees in parallel

Often I work with multiple trees on the same machine, and while e.g. I'm waiting for a test run on one tree, I'd like to do something else on another tree. Sometimes that "something else" is itself a test run.

For example, right now I have a tree with a desktop build and a tree with an Android build, and I'm running |mach reftest <filename>| in my Android build, and I tried to run |mach wpt <filename>| in my desktop build but got:

EnvironmentError: Servers failed to start: ws:8888

File "/home/botond/dev/mozilla/central/testing/web-platform/", line 380, in run_wpt
return self.run_web_platform_tests(**params)

return, **params)
File "/home/botond/dev/mozilla/central/testing/web-platform/", line 40, in run
result = wptrunner.start(**kwargs)

", ".join("%s:%s" % item for item in failed))

It would be nice if doing multiple local test runs like this was supported.

Some test suites have command line options to specify the server ports; using those so that each run is using a distinct server might enable this scenario.
