/**
 * An arena allocator using the Lua state; similar to luaL_Buffer.
 * Initialize the arena with lxl_arena_init(), and you can use lxl_arena_malloc(),
 * lxl_arena_zero() to allocate (and optionally zero) the memory.
 * lxl_arena_free() can be optionally used to free memory, but this is generally not needed.
