9e5a6b509b Implement guard pages (#406) 
Hey, looking for feedback on my guard page implementation. 

I wasn't sure on how to structure the additional windows specific memory
flags, since the emulation backends won't like additional guard flag. I
opted to create a new `memory_permission_ext` enum to hold the guard
flag, and a `nt_memory_permission` struct to wrap the "common" memory
permission flags, with the new extended flags. This struct implicitly
coerces to the original `memory_permission` to reduce the amount of
changes for the PR.

This however meant that I changed signatures of `map_memory` and
`apply_memory_protection` in `memory_interface` to accommodate this new
structure, and was an afterthought.

The `map_nt_to_emulator_protection` function might also need some
attention now, too. For future reference, windows uses
[MiMakeProtectionMask](https://doxygen.reactos.org/d1/d9a/marea_8c.html#adfb66408771a4df77c1056cc2a99ef21)
in ntoskrnl to map `PAGE_*` flags to [MM PTE
constants](https://reactos.org/wiki/Techwiki:Memory_management_in_the_Windows_XP_kernel).

The test added to the `test-sample` binary seems to be passing.

Fixes #21
