Upgrade Insecure Requests: OOPIF support, bugfixes & tests.

This CL fixes several bugs with Upgrade Insecure Requests. The main one
is that URL were compared against the 'upgrade insecure navigation set'
of the frame that is navigating instead of the frame that has initiated
the navigation.

It fixes bug 796538.
8 new tests are added to ensure regressions won't happen anymore.

Finally, it adds the support for OOPIF. The 'upgrade insecure
navigations set' is now replicated across the different processes.

HTML: correct RenderingContext typedef

See whatwg/html#3363.

Remove all remaining references to b2g (web-platform-tests#9052)

Modified location |href| atribute type from DOMString to USVString

location |href| is implemented as URLString which is typedefed
as  (DOMString or TrustedURL).

As per spec, |href| should be USVString. Since URLString is used only for
|href| attribute, So 'DOMString' is modified to 'USVString' in typedef.

Use integer subtraction to calculate movement_x/y

This CL changes the calculation of movement_x/y from
"floor(cur_pos - last_pos)" to "floor(cur_pos) - floor(last_pos)"

We store mouse event coordinates as pointF,
If we have mouse move like: 0 -> 1.4 -> 2.8 -> 4.2
"floor(cur_pos - last_pos)" will get movement:
0->1.4=1; 1.4->2.8=1; 2.8->4.2=1. in total is 3.
So that'll lose fraction part movement.
To get correct movement_x/y, need to use
"floor(cur_pos) - floor(last_pos)" instead.

Set explicit_timeout to true in nested window test environment in blo…

…b URL tests.

This way the tests will timeout when the outer window decides time has
expired, rather than let the nested window decide it earlier.

This mimics the behavior of fetch_tests_from_worker, since
WorkerTestEnvironment always behaves as if explicit_timeout is set to
true.

This should fix spurious timeouts of this test that aren't detected as
timeouts by our test runner (and specifically cases where we don't
actually consider the test as timed out).

CSP: Implement 'prefetch-src' behind a flag.

As discussed in w3c/webappsec-csp#107,
'prefetch-src' gives developers the ability to control the endpoints
from which resources may be prefetched.
