Refactor FileAPI implementation
Most are simple refactoring, cleanups and improvements, but still involving two slightly notable changes:
+ In `filemanager`, now we read the file content based on requested `RelativePos` by `seek` and `read_exact` (rather than `read_to_end` then do slicing). This strategy might be again adjusted in future performance tuning but certainly better than nothing.
+ Also, I cached more file meta-info in both sides and left a block of comment on `filemanager`'s file reading mentioning the snapshot-state problem (not solved now though).

Support non-QWERTY keyboards
Using the ReceivedCharacter event from glutin, we can obtain the actual key characters that the user is pressing and releasing. This gets passed to the script thread along with the physical key data, since KeyboardEvent needs both pieces of information, where they get merged into a single logical key that gets processed by clients like TextInput without any special changes.
Tested by switching my macbook keyboard to dvorak and looking at the output of keypress/keyup/keydown event listeners, as well as playing with tests/html/textarea.html. Non-content keybindings like reload work as expected, too - the remapped keybinding triggers the reload action.

3. Integrate the support of slicing
Implement private browsing for mozbrowser
<!-- Please describe your changes on the following line: -->
Support the `mozprivatebrowsing` attribute on mozbrowser iframes. This separates the non-private and private sessions in terms of cookies, HSTS lists, cached HTTP credentials, HTTP connection pools, and web storage. The private session is shared between all private mozbrowsers, and lasts until shutdown.
