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.

pbr: refactor material management and shader
Introduced a new PBRMaterial resource type. Materials are now fully
described with .material files instead of being hardcoded. Added some
functions to abstract away and simplify set up of PBR shaders.

Logging: colors, non-fatal error level, alt. format for log file
Also removed traceback support entirely as it never produced useful
output.

Some renderer refactoring (mostly API and GLES preparations) (#144)
* Refacor uniforms API:

    - More complete and consistent
    - Type-safety
    - Usage correctess assertions missing for now, planned

* Redesign texturing API: texunits gone, assign textures to sampler uniforms directly

r_texture_create now allocates memory and returns an opaque Texture
pointer; similar changes to the other renderer APIs will follow.

* Framebuffers: make _create return an opaque pointer, add debug label APIs (unused for now)

* opaque pointers and debug label APIs for vertex arrays and buffers

* fix null renderer

* Refactor glsl preprocessing into an independent module

* Separate shader resource management from renderer backend

This makes it possible to add more shading languages and/or include a
transpiler, which will be useful for the GLES backend.

* refactor r_clear into a stateless API

* add r_texture_clear API; fix gl33_framebuffer_clear

* Replace deprecated glsl_objects with objects in all *.prog files

* fix missing texture_clear implementation in null renderer

* remove some dead code in null renderer

* fix GLES segfault

* GLES 3.0 actually has glVertexAttribDivisor

* Query GL for supported GLSL versions (preparing to add shader transcompilation)

Text rendering rewrite and optimizations; some refactoring (#129)
* wip font rendering stuff; hashtable monstrosity is temporary

* various text rendering fixes/improvements

* HashTables™ 3.0

* Add some comments to aid navigating the hashtable macro maze

* overhaul text rendering API; add default and example shaders

* text: implement text_render for spellcard effect; misc fixes

* README: update dependencies

Bye SDL_ttf, hello freetype2.

* text_draw: fix resolution/scale-dependent bugs

* make text_draw fallback to the current shader, fix hud and stagetext

* repair the bgm loading

* fix spell practice mode

* fix walloftext

forgot one site of text_draw earlier

* fix wrapped text rendering

* fix and simplify the hud text shader

* dynamic glyph cache

* implement font size change on window resize/quality setting change/etc.

* rename text shaders for consistency

* preloads for fonts and text shaders

* make the stagetext shader look somewhat better

* text_render: attempt to normalize height

* small improvement for stagetext
