memory: use custom memory allocation wrappers
Introduces wrappers around memory allocation functions in `memory.h`
that should be used instead of the standard C ones.

These never return NULL and, with the exception of `mem_realloc()`,
zero-initialize the allocated memory like `calloc()` does.

All allocations made with the memory.h API must be deallocated with
`mem_free()`. Although standard `free()` will work on some platforms,
it's not portable (currently it won't work on Windows). Likewise,
`mem_free()` must not be used to free foreign allocations.

The standard C allocation functions are now diagnosed as deprecated.
They are, however, available with the `libc_` prefix in case interfacing
with foreign APIs is required. So far they are only used to implement
`memory.h`.

Perhaps the most important change is the introduction of the `ALLOC()`,
`ALLOC_ARRAY()`, and `ALLOC_FLEX()` macros. They take a type as a
parameter, and allocate enough memory with the correct alignment for
that type. That includes overaligned types as well. In most
circumstances you should prefer to use these macros. See the `memory.h`
header for some usage examples.

replay: general refactor
* Split replay.c into multiple files under replay/; improve logical
  separation of replay-related code.
* Separate replay playback state from data.
* Get rid of global static replay struct and avoid unnecessary replay
  copying.
* Replay playback and recording are now independent and may occur
  simultaneously, although this functionality is not yet exposed. This
  enables replay "re-recording" while synthesizing new desync check
  events, possibly at a different rate from the original replay.
* Rate of recorded desync check events can now be controlled with the
  TAISEI_REPLAY_DESYNC_CHECK_FREQUENCY environment variable. The default
  value is 300 as before.
* Probably other stuff I forgot about.

Don't redefine standard complex macro; use a new cmplx typedef
This also introduces `float32`, `float64`, and `real` typedefs to be
used in place of `float` and `double` later. `real` is for game code and
other places where we don't particularly care about the precision and
format of the underlying type, and is currently defined to `double`.
`float32` and `float64` should replace `float` and `double` respectively

Refactor matrix stack API to get rid of matrix mode (#177)
This replaces the r_mat_foo functions with specialized r_mat_{mv,tex,proj}_foo counterparts that operate explicitly on the modelview, texture, and projection matrix stacks respectively.

Emscripten compatibility (#161)
* Major refactoring of the main loop(s) and control flow (WIP)

run_at_fps() is gone 🦀

Instead of nested blocking event loops, there is now an eventloop API
that manages an explicit stack of scenes. This makes Taisei a lot more
portable to async environments where spinning a loop forever without
yielding control simply is not an option, and that is the entire point
of this change.

A prime example of such an environment is the Web (via emscripten).
Taisei was able to run there through a terrible hack: inserting
emscripten_sleep calls into the loop, which would yield to the browser.
This has several major drawbacks: first of all, every function that
could possibly call emscripten_sleep must be compiled into a special
kind of bytecode, which then has to be interpreted at runtime, *much*
slower than JITed WebAssembly. And that includes *everything* down the
call stack, too! For more information, see
https://emscripten.org/docs/porting/emterpreter.html

Even though that method worked well enough for experimenting, despite
suboptimal performance, there is another obvious drawback:
emscripten_sleep is implemented via setTimeout(), which can be very
imprecise and is generally not reliable for fluid animation. Browsers
actually have an API specifically for that use case:
window.requestAnimationFrame(), but Taisei's original blocking control
flow style is simply not compatible with it. Emscripten exposes this API
with its emscripten_set_main_loop(), which the eventloop backend now
uses on that platform.

Unfortunately, C is still C, with no fancy closures or coroutines.
With blocking calls into menu/scene loops gone, the control flow is
reimplemented via so-called (pun intended) "call chains". That is
basically an euphemism for callback hell. With manual memory management
and zero type-safety. Not that the menu system wasn't shitty enough
already. I'll just keep telling myself that this is all temporary and
will be replaced with scripts in v1.4.

* improve build system for emscripten + various fixes

* squish menu bugs

* improve emscripten event loop; disable EMULATE_FUNCTION_POINTER_CASTS

Note that stock freetype does not work without
EMULATE_FUNCTION_POINTER_CASTS; use a patched version from the
"emscripten" branch here:

    https://github.com/taisei-project/freetype2/tree/emscripten

* Enable -Wcast-function-type

Calling functions through incompatible pointers is nasal demons and
doesn't work in WASM.

* webgl: workaround a crash on some browsers

* emscripten improvements:

    * Persist state (config, progress, replays, ...) in local IndexDB
    * Simpler HTML shell (temporary)
    * Enable more optimizations

* fix build if validate_glsl=false

* emscripten: improve asset packaging, with local cache

Note that even though there are rules to build audio bundles, audio
does *not* work yet. It looks like SDL2_mixer can not work without
threads, which is a problem. Yet another reason to write an OpenAL
backend - emscripten supports that natively.

* emscripten: customize the html shell

* emscripten: force "show log" checkbox unchecked initially

* emscripten: remove quit shortcut from main menu (since there's no quit)

* emscripten: log area fixes

* emscripten/webgl: workaround for fullscreen viewport issue

* emscripten: implement frameskip

* emscripter: improve framerate limiter

* align List to at least 8 bytes (shut up warnings)

* fix non-emscripten builds

* improve fullscreen handling, mainly for emscripten

* Workaround to make audio work in chromium

emscripten-core/emscripten#6511

* emscripten: better vsync handling; enable vsync & disable fxaa by default

Premultiplied alpha (#133)
* WIP premultiplied alpha

* WIP color API rework (doesn't build yet; lots of things left to convert)

* convert everything remaining to new Color api except stage*_event.c files

* convert the stages to new Color api. builds & runs now; still many rendering errors

* fix the bullet shader for premultiplied alpha

* fix masterspark, graphs and stage 1 fog clouds

* fix marisa_b and most of spellcards

* Add deprecation warnings for BLEND_ADD and PFLAG_DRAWADD

* fix a segfault in stage 6

undo accidental earlier change

* fix text_hud.frag.glsl

* fix scuttle bg and remaining stage3 BLEND_ADDs

* fix marisa laser opacity

* hacky fix for myon

The old implementation relied on alpha being stored inside p->color. In
premul alpha this doesn’t work and functions like color_set_opacity
can’t solve this i think.

So I tried messing around with it until it looked somewhat similar.

* fix marisa_b stars

* remove color_set_opacity i overlooked

* more plrmode blending changes

* fixup additive blending in stage 1

* various premultiplied alpha fixups for bosses and enemies

* stage 2 premul alpha fixups

* stage 4 premul alpha fixups

* stage 5 premul alpha fixups

* stage 6 premul alpha fixups

* make lasers also use the PMA blend mode

* remove PFLAG_DRAWADD and PFLAG_DRAWSUB

* fix remaining PMA issues in menus

* lame extraspell bg workaround

* fix item alpha

* make marisaA lasers look somewhat like in master

* fix marisaA bomb background fadeout

* fixup various r_color4 calls

* fix myon

* remove dead code

* fix use of BLEND_ADD in player death effect

* fix myon shot trails (broken on master as well)

* fix myon shot fade-in

* extend the sprite shaders custom parameter to a vec4

* fix youmuB stuff and make it look somewhat better.

the code looks even worse though.

8668021710 Replaced strncat/strncpy with strlcat/strlcpy
The strncat/strncpy functions have dangerously counter-intuitive
semantics. They are meant to be used with fixed-width,
non-null-terminated strings, which is in, 99% cases, not what you want.

The strlcat/strlcpy ones are non-standard, however SDL provides its own
implementations on platforms that do not have them.

31ac12f6e7 Improved replay structure and API
All events are now stored at the end of the file, after the metadata of all stages.
It's now possible to load a replay partially to examine the metadata, and optionally load the input events later if needed.
This is not used yet. The replay menu code will be updated to make use of this feature soon.
