input: stop capturing mouse movement if window is hidden without first losing focus

Fixes players looking all around after they alt+tabbed.

Moves the logic for selecting the mouse mode out of screen drawing and
into SDL event handling where it's unaffected if we early-out of drawing
the frame.

Prevents mouse "grab" (raw/relative mode + cursor hiding) in a few
"loading" situations.

vid: implement monitor selection with instant cvar changes

Adds cvars: vid_display, vid_info_displaycount

Prints the monitors detected at startup and on hotplug.

Requires SDL headers >= 2.0.18 at build time.
At runtime older versions should still work but may lack some functionality.

May not work properly or at all if vid_desktopfullscreen is 0.

May require vid_restart after hotplug events.

---

Changes existing cvars vid_fullscreen, vid_desktopfullscreen, vid_resizable,
vid_borderless to apply instantly.

Also (for windowed mode) works around window managers that move the
window after SDL creates and centres it (typically when adding a
titlebar), so the crosshair is always at the centre of the monitor.

Adds some missing SDL_WINDOWEVENT enumerations.

Changes the GL viewport size retrieval from screen coordinates to
pixels, which is a prerequisite for "HIGHDPI" aka "Apple Retina"
support.

vid_vsync: fully support adaptive, remove polling, print better errors

Adaptive vsync was partially supported: it worked if set before window
creation but not if toggled on afterwards, and wasn't mentioned in the
cvar description.

The immediate application of `vid_vsync` cvar changes was implented by
polling, which was ok for one cvar but I'll be making more vid_ cvars
apply immediately (no vid_restart needed), and don't want to poll for
things that rarely change every frame.

SDL is now queried for the current state of vsync instead of storing
what we believe to be the current state.

If the setting can't be applied the reason (as reported by SDL) is now
printed.

NudgeOutOfSolid: fix "random" failures on slightly inclined planes

History:
This epsilon value was first added to the nudge distance in
31e7715cffcebfd400b8473f3b2d3dc80937fc5a
and was replaced with bbox expansion in
25c09ca585e81bf9eb236a339ae5dcd64f63b679

With the expansion approach we need to compare to separation to make
"good location" detection reliable, partly to avoid float precision
problems, partly to avoid compatibility problems with normal TraceBox.
For example: we drop an entity to floor successfully with TraceBox, but
then NudgeOutOfSolid decides it's in solid.
