* Refactoring of macOS `virtualkeycode` fix (rust-windowing#752)

* Applies requested changes as per pull request discussion (rust-windowing#755).

XNextEvent will block for input while holding the global Xlib mutex.

This will cause a deadlock in even the most trivial multi-threaded
application because OpenGL functions will need to hold the Xlib mutex
too.

Add EventsLoop::poll_one_event and EventsLoop::wait_for_input to provide
thread-safe functions to poll and wait events from the X11 event queue
using unix select(2) and XCheckIfEvent.

This is a somewhat ugly workaround to an ugly problem.

Fixes rust-windowing#779

…#810)

* fix command key event left and right reverse on macOS

rust-windowing#808

* update changelog

* Add additional numpad key mappings

Since some platforms have already used the existing `Add`, `Subtract`
and `Divide` codes to map numpad keys, the X11 and Wayland platform has
been updated to achieve parity between platforms. On macOS only the
`Subtract` numpad key had to be added.

Since the numpad key is different from the normal keys, an alternative
option would be to add new `NumpadAdd`, `NumpadSubtract` and
`NumpadDivide` actions, however I think in this case it should be fine
to map them to the same virtual key code.

* Add Numpad PageUp/Down, Home and End on Wayland
