* Fix keyboard state change detection on RPI

* Rework RaspberryPi evdev keyboard input.

- Extract evdev keyboard handling into PollKeyboardEvents()
- Move keyboard polling to main thread
- Rename EventThreadSpawn() to ConfigureEvdevDevice() as it doesn't necessarily spawn threads
- Remove unused code (KeyEventFifo and lastKeyPressed)

* Replace tabs with 4 spaces.

* Update CMakeOptions.txt

* Update config.h.in

I usually try to avoid any return in the middle of functions, I try to keep them always at the end of the functions.

* Don't create an ortho matrix when the viewport is 0 in any axis.
Not all compilers divide by 0 and return inf, some segfault.
The matrix is not used by anything when minimized, so it just needs to not be called.

* Better fix that always ensures the rlgl matrix is always valid

* Better fix that always ensures the rlgl matrix is always valid

Resolves #1495
This line allocated some memory that was already allocated in the beginning of the function and was essentially creating a leak.

Fix run .cmd for win

* Don't use DrawRect to clear an image, a pixel loop is an order of magnitude faster.

* Update ImageDrawRectangle to be faster too.

* Added a new utility function to get the current monitor.

Some of the other functions rely on passing on a monitor id but we only have a function for querying the count of monitors available.

* Updated the comment to correctly reflect the function action

This monitor should even probably be passed as an id instead to make it more consistent with the rest of the API but this would break existing applications so I am hesitant to change the function signature directly.

Sorry for that, At least i'm correct now ;)
