Use proper memory allocation algorithm

[JayFoxRox]

Right now, all memory is just allocated and never free'd. This leads to > 500 MB memory consumption even before the first frame.

A memory allocation from some libc which works with 32 bit should be stolen.

Maybe using https://github.com/rhempel/umm_malloc would be an idea. It is licensed under the MIT License and would offer: void umm_init( void ); void *umm_malloc( size_t size ); void *umm_calloc( size_t num, size_t size ); void *umm_realloc( void *ptr, size_t size ); void umm_free( void *ptr );
