Import w3c tests for the service workers

third_party/WebKit/LayoutTests/W3CImportExpectations

 # This file controls which subdirectories of the w3c test repos we do (or don't) import.
 #
 # This file acts as a blacklist; directories and files not listed here will automatically
 # be found and imported. The only exception is that the manual tests (i.e. those with a
 # filename ending with "-manual.html" or "-manual.htm") are never imported.
 
 # When removing blacklist entries:
 # * Comment out the line rather than deleting it, to show it is intentional
 # * Change [ Skip ] to [ Pass ]
 # * Add a leading comment: ## Owners: user@example.com

This comment out format is confusing. tkent what is the convention here? What is
the difference between

# imported/wpt/service-workers [ Pass ]
and 
imported/wpt/service-workers [ Pass ]

[tkent, 2016/10/13 04:48:21]

The convention is to prepend '# '.  I don't know if W3CImportExpectations
supports anything other than 'Skip'.

Ah OK. I saw some Pass expectations (wpt/dom, wpt/svg) which was confusing.
