* Update compilation warning flags
Removed the -Wall flag that allow many warnings and added manually all the warning flags that don't generate warnings in the src/external folder.
Specifically, these are some of the flags reporting errors in src/external:
-Wmissing-prototypes
-Wunused-variable
-Wunused-value
-Wunused-parameter
-Wunused-function
* Uptade compilation flags in examples with missing -std=c99
Added in a check for x86 and x86_64 branches of android
Added in $(OS) checks to see if we're running on windows or *nix
Added a default location for android ndks and sdks at /usr/lib/android
* added multi channel sound replay to raudio
added -fPIC to Makefile for Linux
added simple lighting and audio multi channel to examples Makefile
* not properly reporting audio buffer pool size...
With v2.5.0 out, increment API_VERSION, so binaries dynamically linked
against the released raylib aren't accidentally paired with a development
or later released raylib that may be incompatible.
Found some issues when building for web using latest emscripten 1.38.30, traced the error and found that eglGetProcAdress does not return function pointers for VAO functionality, supported by extension.
It requires more investigation but now it works (avoiding VAO usage)
The idea is supporting additional raygui and physac modules building with raylib but those modules are distributed as header-only libraries and it makes a bit dificult to build them inside raylib...
Planning to promote raudio module as a simple and easy-to-use front-end for the amazing mini_al library, so the name change.
Name comes from raylib-audio but in spanish it also remembers to word "raudo", meaning "very fast", an analogy that fits perfectly to the usefulness and performance of the library!
Consequently, raylib version has been bumped to 2.4-dev.
