This commit restructures the codebase to melt the milepost platform layer into the main orca codebase. Here's a list of commits squashed in this update: - move angle files to ext/ and pull includes/libs from there when needed - remove milepost/ext/angle_headers - Collapsed milepost/ext into ext - Collapse milepost/scripts into scripts/ - collapse milepost/resources into resources/. WARN: this temporarily breaks milepost's native examples - collapse milepost/test into test/ - renamed test/ to tests/ - build milepost directly into build/bin - remove unused GLES and KHR folders from sdk/ - reorganizing milepost directory tree into app, graphics, platfrom, ui, util - collapse milepost/src to src/ - Move all native examples to sketches/ and remove milepost repo - Moving sketches resources into their own shared folder separate from the runtime's resource folder - Moving all binding code to src/wasmbind - Moving all binding code to src/wasmbind - pong: fix typo in error log - fixing log parameter order - add error logs to mg_image_create_* - Fix build scripts on windows - fixed include mistake after rebase - collapsing milepost.{h|c|m} to orca.{h|c|m} and moving from sdk/ to src/ - rename orca_app.h/main.c to runtime.h/c - collapsed sdk/ to src/ - put old sdk files into their respective dirs - renamed canvas_api.json to surface_api.json - moved all stb headers in ext/stb/ - remove unused OpenSansLatinSubset.ttf font - moving cstdlib to src/wasmlibc and removing some duplicates with src/platform - move libc stdarg and string functions from platform/ to wasmlibc/ - rename wasmlibc to libc-shim to reflect non-completeness - Expose abort/assert variadic functions and macros to orca apps, and forward libc-shim abort/assert to these - move Orca API runtime implementations to runtime_xxx - fix missing math constants when including math.h with msvc in graphics_common.c - Change name of runtime to orca_runtime. When bundling on Windows, change name of runtime executable to the name of the app.
