Currently, a timeout that sets a timeout can cause loop.run to block forever.
Also, cleanup URL stitch with leading './'. The resulting URL was valid, but
since we use the URL as the module cache key, it's important to resolve various
representations of the same URL in the same way.
- Pages within the same session have proper isolation
- they have their own window
- they have their own SessionState
- they have their own v8.Context
- Move inspector to CDP browser context
- Browser now knows nothing about the inspector
- Use notification to emit a context-created message
- This is still a bit hacky, but again, it decouples browser from CDP
Combine uri + rawuri into single struct.
Try to improve ownership around URIs and URI-like things.
- cookie & request can take *const std.Uri
(TODO: make them aware of the new URL struct?)
- Location (web api) should own its URL (web api URL)
- Window should own its Location
Most of these changes result in (a) a cleaner Page and (b) not having to carry
around 2 nullable objects (URI and rawuri).
