Fixes warnings from rust-lang/rust#44229 when `--enable-commonmark` is
passed to rustdoc.
This is mostly a global find-and-replace for bare URIs on lines by
themselves in doc comments.
Use Option instead of ServoUrl for url in opts
Cleaner mapping from parse_url to url_opt
Add comment about url parsing error
Print reason for parsing error
Remove comment about warning
Add home url when openning new browser window in CEF
Fix merge error
The DebugOpts struct uses the Default trait to set all the values
to false initialily. So bools in the DebugOpts struct must be

No doubt there are still some bugs and missing features related to subpixel text anti-aliasing.
But enabling by default should allow us to detect these and fix them.
If we run into any major issues, this is a standalone commit that can be reverted while we fix the problem.
This was used by the old compositor of which only the ghostly echoes of
old commits remain. Since it's been unused for quite some time, it is
probably safe to remove it.
Also remove the obsolete `--cpu` and `--gpu` renderer flags,
which also are no longer used.
Update tests and wptrunner to not pass these flags.
wptrunner changes have been upstreamed in:
- w3c/wptrunner#224
- w3c/wptrunner#226
Index the session past correctly when discarding.
