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.

Various fixes & improvements for concurrent loading (#235)
- RESF_UNSAFE is removed.
- Resources that don't have to be finalized on the main thread can load
completely asynchronously.
- A thread waiting for a concurrent task to complete can start executing
that task itself if it hasn't started yet.
- Refactor the resource loading interface, add support for load-time
dependencies.
- Main-thread finalization of asynchronously loaded resources is now
spread out across multiple frames to mitigate frametime spikes.
- Remove some archaisms from the resource management code.
- Fix potential hashtable synchronization issue.
- Fix some deadlock edge cases.
- Don't spawn more worker threads than there are CPU cores (degrades
performance).
- Add TAISEI_AGGRESSIVE_PRELOAD env variable to attempt to aggressively
discover and preload every possible resource.
- Make r_texture_fill{,_region} expect optimal pixmaps, so that it's
never forced to convert them on the main thread. The optimal format may
be queried with the new r_texture_optimal_pixmap_format_for_type API.
These functions will also no longer needlessly copy the entire image
into a staging buffer - previously they did this even if no conversion
was needed.
- Other random changes to facilitate the stuff above.

The overall effect is somewhat faster load times.

Of course it's still all terrible and full of lock contention because I
suck at concurrent programming, but it's not worse than it was.
Probably.

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)
