rexm used to assume certain paths existed and then `_putenv()` them into `PATH`, which is very error prone. `make` was also assumed, though `mingw32-make` seems to be more common on Windows. Since this shifts things to expect the user to setup their environment, I added some explanation to the README as well.
OP_TESTLOG still uses a hardcoded path when doing web testing (`BUILD_TESTING_WEB`,) unfortunately.
rexm could crash and corrupt examples_list.txt when adding a new example in the textures category. This happened because the tool searched for the category name as plain text, and "text" happens to be part of "textures" (and shows up inside names like core_render_texture), so it sometimes found the wrong spot and inserted the new example in the middle of an unrelated line.
This fix makes the search look for the exact category boundary instead of just any matching text, so it always finds the right place. It also fixes a small out-of-bounds issue that could happen specifically with the audio category, since it's the last one in the list.
Tested by creating a new textures example and a new audio example, both now work correctly and the examples list stays intact.
* Update GLFW to 3.5.1
* Remove cocoa_time.c from rglfw.c
* Add macos_time.c to rglfw.c
* Redo changes from pull request #3863
* Makefile: add QuartzCore framework when building for macOS
* Add QuartzCore when building for macOS to other build files
* Remove unused GLFW dependencies
Redesign has been conditioned by the usage of those functions on `rexm`, `rpc` and other tools; for many use cases a static buffer is enough and way more comfortable to use.
ADDED: `TextInsertAlloc()`, `TextReplaceAlloc()`, `TextReplaceBetweenAlloc()`, alternatives with internal allocations
