src: deprecate strdup(), use mem_strdup() explicitly
This fixes a nasty bug that manifests on windows when building without
precompiled headers. util/stringops.h used to silently replace strdup
with a macro that's compatible with mem_free(). This header would
typically be included everywhere due to PCH, but without it the strdup
from libc would sometimes be in scope. On most platforms mem_free() is
equivalent to free(), but not on windows, because we have to use
_aligned_free() there. Attempting to mem_free() the result of a libc
strdup() would segfault in such a configuration.

Avoid the footgun by banning strdup() entirely. Maybe redefining libc
names isn't such a great idea, who knew?

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.

Implement Robin Hood hashing (#200)
* Implement Robin Hood hashing

This replaces the previous separate chaining implementation. This
approach is more memory-efficient, cache-friendly, and puts much less
stress on the memory allocator.

* Replace crc32 with fnva1

Also attempt to make the compiler pre-hash as much stuff as possible at
build time.

Lots of disorganized (mostly) visual overhaul (#156)
* WIP some projectile effects

* fix segfault

* Laser smoothing and glow via post-processing blur magic

TODO: make it optional

* fix memory corruption

* fix memory corruption for realsies now

* fix color_get_hsl for out-of-range colors

* some more bullet flare tweaks

* some lame clear effect workarounds

* spawn bullet flares after frame 0; looks better and fixes some problems

* New baryon explosion; fix petal_explosion; leanify everything

* Add missing bullet flare sprite, rebuild main atlas

* improve batching efficiency with bullet spawn flares

* forgot git add

* Group projectiles/particles by shader where possible

* Another take on baryon explosion; make fg framebuffers 16bit

* WIP some settings for toasters

* remove stupid debug log

* microoptimization that probably does nothing anyway

* somewhat more intuitive quality settings

* Whitelist more particles (MarisaB is on hold)

* Whitelist (and fix) some more stage6 particles (mostly ToE)

* Add a spell name background

* Experimental radial healthbar for bosses

* healthbar tweaks

* thiccer healthbars in response to feedback

* remove healthbar survival timer; just fade out on survivals

* Add linear healthbars option; WIP other boss HUD tweaks

* Use the proper spell card name format

* New font and some random garbage to go along with it

* Generate static font outlines for use in text shaders

* Use outlines in overlay text shader

* Complete boss HUD/healthbar fading logic

* fix boss timer limit

* stage5 bombs explosion effect

* split PFLAG_NOSPAWNZOOM into PFLAG_NOSPAWNFLARE and PFLAG_NOSPAWNFADE;

introduce PFLAG_NOSPAWNEFFECTS which disables both (it's just the two
values OR'd together)

simplify vampiric vapor bullet spawning effect

* Remove spawn fade-in from super-fast stage5 fairy projectiles (limiters)

* lower particle density in v.vapor in minimal mode

* graze effect tweaks

* fix text shortening, tweak replay menu layout

* stupid debug spam

* revisit grazing effects again

* dumb debug spam again

* improve boss attack timer

* overlay effect for boss deaths (similar to the player one)

* spice up spellcard declaration (HUD)

* don't spawn boss death overlay if fleed

* modify Exo2 font to use tabular figures

* adjust replay menu for the font change

* draw timer & power with standard font (phasing out the numbers font)

* WIP new HUD; random fixes/tweaks

* hud: move difficulty indicator

* hud: move debug stuff around

* preloads, mostly

* fix youmuA batching conflict

* shitty workaround for the shitty screenshake shit

* remove extraspell lag by stopping to draw stagebg sooner

which is possible because extra spells have a different spellcard_intro timing. Fun fact of the day: the duration of spellcard_intro is always ATTACK_START_DELAY_EXTRA even for normal spells!

* new stain particle

*  i disabled background rendering…

* "batch" marisa_b masterspark draws

* remove these once a new atlas is generated

* make toe quick again

* hopefully fix all occurences of changed stain and ScaleFade behavior

* tweaking reimu_a and toe boson launch effects

* make lhc fast again

* softer involnerability effect

* fix stage 1 snow on the water bug (and improve performance)

translated the time to the future a bit because it only seemed to be an issue for small time values

* remove unnecessary spawnflare from toe

* tone down extra spell start effect

* experimental ReimuB gap shader optimization

* fix python3 shebangs

* generate simple blur shaders w/ hardcoded kernels

* New loading screen

* lasers: fix incorrect draw hook registration

* add webp support for atlas generator

* Use ImageMagick for atlas composition (adds 16-bit support)

* Atlas maintenance

* make the vampiric vapor bullets less prone to invisibility

* Revert a few particles to the quadratic fade curve

* experimental baryon effect

* improve baryon sprites

* disable the baryon effect on minimal postprocessing setting

Improve filename timestamps (screenshots, replays)
* Get rid of timezone information.
    * If possible, add milliseconds precision. This is useful when
    taking several screenshots in quick succession.
