CMake: Add options to use -fsanitize={address,undefined} To make bugs like #485, #486, #487 and #488 easier to find in future.

Add memory sanitizer for better debug

CMake: Explicitly ask for C99 support Otherwise using a compiler that defaults to -std=c89 or -std=gnu89 will fail. Example: http://www.cpantesters.org/cpan/report/abb85066-d283-11e7-9926-b2f4efb9c382 Apparently, -m32 Travis CI build was broken: -m32 was overridden by -std=gnu99. This fixes that.

jar_xm: Workaround for unaligned pointer accesses jar_xm.h does some shady pointer casts leading to unaligned accesses and breaking strict aliasing. x86 has special circuitry for doing unaligned accesses, but on other architectures, it may trap and require kernel fix-up or crash outright. With this patch, one obstacle in porting raylib to the GameBoy Advance has been removed. Go for it ;-) To avoid having to rewrite that `mempool' code, insert padding before structs and instruct the compiler (GCC, most importantly), to be gentle when optimizing. This fixes #490 (Unless we got ourselves 256-bit pointers, if so, hello future!)

include(CheckFileSystemSymlinkSupport)
CMake: Don't create symlinks on unsupporting file systems (#539) Panders to the idiosyncrasies of my work flow: I have my raylib build directory mounted as a VirtualBox vboxfs for use with my Linux VM, but vboxfs doesn't support symlinks, while raylib shared library versioning on Unix expects symlinks to work. If this happens, library versioning is now disabled on Unix with an error message instead of just failing the build.
