Fix missing free on GrowableBitSet. init_new/init_temp for GrowableBitSet, LinkedList, List, HashMap, DString, ByteBuffer. Interface to_string renamed to_new_string. Change in allocator usage, malloc is now heap. Added new_array, new_zero_array, new, new_clear, clone. Concat => concat_new. string::printf => string::new_format, string::tprintf => string::tformat. "to_*" are now "to_new_*" and "to_temp_*". "from_*" is "new_from*"
