CSP: Use the served CSP header for dedicated workers

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Daniel Bates]

We should merge <https://src.chromium.org/viewvc/blink?view=rev&revision=194094> and <https://src.chromium.org/viewvc/blink?view=rev&revision=194143> (in order).

Use the served CSP header for dedicated workers

This CL makes workers obey the CSP that was served as a header along
with the worker script, instead of inheriting the CSP from the document
that spawned the worker. (Blob and file URLs still inherit the CSP from
the parent document.)

Patch and Layout Tests

Updated patch to inherit CSP from owner document of worker when script URL of worker is a file URL as per comment #0. Added tests LayoutTests/fast/workers/worker-inherits-csp-blocks-{eval, xhr}.html to ensure we do not regress this behavior.

r=me. I don't know why the patch will not apply on the WK2 bot, but presumably its a machine-specific issue. Please watch test results carefully after landing.
