This commit renames `Frame` -> `UntypedFrame` and `Page` -> `Frame`.
So do other concepts in the following list:

- `PageMeta` -> `FrameMeta`,
- `FrameMeta` -> `UntypedMeta`.
This commit also re-organized the source in the `mm/page` and `mm/frame`
module to accommodate the changes.

Respect user-defined exit signal in clone() and clone3()
...
When calling clone() and clone3(), the user is allowed to specify a
signal to be sent to the parent process on exit. Respect this value by
storing it in the Process struct and sending the signal on exit.
Add a test as well to verify that the signal is properly delivered to
the parent.
