c5f10dd879 Switch to a new, MSYS2 based build environment for Windows.
Highlights are:
- Since MSYS2 is much more unixlike than our old build environment we
  can remove most Windows specific hacks from the Makefile.
- MSYS2 has an package manager, the build environment can be updated
  by "pacman -Syu" just like an ordenary Arch Linux installation.
- Parallel builds are now working.
- git is integrated into the build envirment.
- zlib is now linked as a dynamic lib.

After this commit the old bild environment will no longer work! The
latest version must be downloaded and extracted to C:\MSYS2. Get it
here: https://deponie.yamagi.org/quake2/windows/build/

865e97514d GL3: Render Model shadows last, reduce global variables in gl3_mesh.c
The model shadows are rendered after all entities are rendered.
This fixes them making entity brushes below them translucent (#194)

The model rendering code used lots of global variables, many of them
totally superfluous (esp. currententity, currentmodel).
I refactored the code to use less global variables (this was at least
partly needed to render the shadows later).
So this looks like lots of changes, but many of them are just using
"entity" instead of "currententity" or "model" instead of "currentmodel"

9751caac85 GL3: Optimize shadow rendering
now DrawAliasShadow() only uses one draw call per model, pretty much
like DrawAliasFrameLerp()

b45a6d8ef9 GL3: Simple Stencil-Shadows
Like GL1 gl_shadows + gl_stencilshadows: no shadow volumes, but looks
ok apart from standing over edges

The gl_stencilshadows cvar isn't used in GL3, it always uses the stencil
buffer if available (and if gl_shadows != 0)

This still needs performance optimizations: Like the GL1 impl it takes
lots of draw calls per model, it could be done with one per model like
when rendering the actual model.

ff6e7ede26 GL3: Apply scroll offset to x also for transparent scroll surfs

dd007f340a Apply scroll offset the x coordinate and not to y.
When applied to y SURF_FLOWING textures are scrolled into the wrong
direction. I guess that in GL1 the offset is also applied to x.

98276aeb91 Empty SDLs event queue when starting cinematic playback.
Sometimes cinematics are skipped after the first frame even if the
player didn't press any key. I'm unable to reliable reproduce that,
so my educated guess is that one or more events are still waiting in
SDLs event queue.

For example, during intermission IN_Update() is not called for 5
seconds, key presses by impatient players are just added to the queue
and not processed. The first event is used to skip leave the
intermission, the second event skips the cinematic...

Fix this by implementing a new function IN_FlushQueue() to flush SDLs
event queue and calling it when starting cinematic playback. Yes, this
is just another layer violation. :(

eb2a11f0b2 Unqueue raw samples when the menu is entered during cinematic playback
When the client is paused (either explicit or by entering the menu or
console) the cinematic is paused, too. Therefor no more sound samples
are generated and added to the playback queue, the existing samples are
played over and over again. Until now these samples weren't hearable,
because OpenAL marked them as processed and AL_StreamUpdate() removed
them from OpenALs playback queues. This changed in the previous commit,
now the stay in OpenALs queue and are hearable.

Fix this by calling AL_UnqueueRawSamples() when the menu or console is
entered during cinematic playback.

12fba237c2 Fix raw samples playback with newer openal-soft versions.
Newer openal-soft versions changed the way how the processed buffers are
counted when in AL_STOPPED state. Previously only processed buffers were
counted, now all buffers are. Change our unqueue logic to match this new
behavior.

This was debugged and fixed @xorw, I'm just committing the patch. This
closes issue #185.

a47a9daf67 Fix crash if the requested gl_msaa_samples are unavailable.
For some reasons setting the MSAA fails at window creation and not at
GL context creation. And of course SDL is unable to detect before, that
the requested number of MSAA samples is invalid... Implement a work
around: Fall back to gl_msaa_samples == 0 if the window cannot be
created.

The CMakeLists.txt used the same linker flags for all target, grossly

7d53e6ebf2 Quirk map bug in waste3 (secret not counted)
there's a target_secret (with targetname "t117"), but no one triggers
it - that's why the help computer shows four secrets, but you can only
get three of them.
Now when you open the door in front of the hidden secret armor
(by shooting it), it'll trigger the target_secret and you can get all
four secrets.

0608eed7c3 Fix order of the video menu items.
The internal order of the items is determined by Menu_AddItem() and
not the y position. Without this change the cursor didn't jump from
item to item, but from the mode list box to the aspect list box,
skipping the brightness slider.

df86c46e57 Several adjustments to the visual impression.
- Bump vid_gamma to 1.2 in both GL1 and GL3. A default value of 1.0 is
  too dark.
- Lower gl3_overbrightbits to 1.3, the previous value of 1.5 was too
  bright. This can be seen in later units, for example on mine1 some
  textures blended into white.
- Lower gl3_particle_size to 40. A value of 60 may be okay, but with
  gl3_particle_fade_factor 1.2 the particles take up too much screen
  estate in close range combat.

With this changes GL3 looks (at least for me) nearly the same as GL1
rendered through the removed multitexturing path.

8316dfe3d9 Change the dynamic light cuttoff from 64 to 52.
64 was the cutoff used by GL1. Testing showed that 52 is better suited
for GL3. Good levels to test this can be found in the Mines unit.

0314eafdaa Cap dynamic light intensity / brightness to 3.
Without capping the brightness entity models may fade into pure white
which looks ugly. This can be seen when several flyer fire blaster
bolds onto the player or when multiple barrels are exploding. This
change was suggest by @DanielGibson, I'm just the messenger.

8c665b826c Do not enforce the Vrect to have even width and heights.
I really don't see why this constraint was ever necessary. It leads to
one line of pixels not rendered either at the bottom or the right edge
of the screen. In GL1 for whatever reasons this line is just black, in
GL3 garbage is drawn.

e510bfc281 Fix render artifacts around health points when the HUD is scaled.
In SCR_DrawFieldScaled() the HUD scale factor wasn't taken into account
when calculating the screen area affected by the change. Therefor wrong
coordinates were passed to SCR_AddDirtyPoint() and a part of the changed
area wasn't marked dirty, leading to render artifacts.

This bug was present since HUD scaling was first introduced.

7b5e13d4ff Add GL1 and GL3 refresh libraries to the CMakeLists.txt
I hope that I've referenced all headers required by the libraries. If
I missed some compilation will work but IDEs like Clion won't be able
to deduce all symbols.

Before this change cmake overlinked the q2ded binary and the game.so
game library. Now it is also the case with ref_gl1.so and ref_gl3. This
will be fixed in a later commit.
