Replace `mem_free` by `free`, and `mem_alloc` by `malloc` or `calloc` (the latter one being used to allocate a zeroed array of elements, sometimes, this makes a call to `mem_zero` superfluous). This results in having to remove `mem_stats` which previously recorded the number of allocations and their size that the Teeworlds code did directly. Remove OOM handling in `src/game/client/components/binds.cpp`. Remove needless copying in the CSV code in `src/game/client/components/statboard.cpp`.
