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.

Texturing overhaul: GPU compression, sRGB sampling, swizzles, etc. (#240)
* WIP compressed textures, swizzles, sRGB sampling, ...

* refactor texture type info & fix random bugs

* fix preprocessing of sRGB textures

* handle y-flipped basis textures

* glcommon: better WebGL compat for compressed format detection

* missed WEBGL_compressed_texture_pvrtc

* implement compressed texture xcoding and uploading

* Add basis_universal submodule

* Reorganize texture loader code

Clean up some code
Isolate Basis Universal loader into a separate module

* Add wrapper script for encoding .basis textures

* basisu: honor custom metadata written by the mkbasis.py script

* mkbasis.py: add --incredibly-slow and --dry-run

* Move pixmap code from util/ to pixmap/

* Add an on-disk transcode cache for basis textures to speed up loads

* Compress texture cache with zlib

* Use readable format names for basisu cache filenames

* basisu: mip bias test code

* basisu: small caching cleanup

* add TAISEI_BASISU_MIP_BIAS env variable

* Improve OpenGL format matching heuristics

* Document considerations for compressed format priority

* Remove dead code

* Enable two forgotten formats, BC3_RGBA and ATC_RGBA

Also prefer BC7 over BC1/BC3

* Recognize GL_ANGLE_compressed_texture_etc for ETC2 textures

* Default depth buffers to 24-bit; remove ANGLE hack

* Fix glcommon_check_extension for GLES2/legacy gl

* Add renderer feature bit for texture swizzle masks

* glcommon: Fixup internal formats for GLES2

Sized internal formats are not allowed in GLES2

* Fix emscripten compile errors

* Update basis_universal

* remove more dead code

* revert irrelevant stage4 change

* shut up UBSan

* basisu: shut up some debug spam

* Add normalmap sampling helper to util.glslh

* basisu: add a gray-alpha mode

* mkbasis.py: Abort if image dimansions aren't multiples of 4

* Add basic Basis Universal encoding documentation (WIP)

* doc/basisu: Add paragraph about modes; minor tweaks

* basisu: workarounds for GL texture size requirements

* gles20: fix uncompressed sRGB formats

* Partial workaround for missing swizzles in gles2 and webgl

* remove invalid assertion

* New renderer API to expose glDrawBuffers-like functionality

* stagedraw: disable all color outputs for copy_depth pass

required for WebGL compatibility

* support GL_ANGLE_request_extension

* emscripten: include *.basis in gfx package

Also fix a potential problem when more than one .pkgdir is used to
construct emscripten packages

* Don't rely on emscripten runtime to enable webgl extensions
