Cleanup/refactor: Add new BLI_string_util.

Things like `BLI_uniquename` had nothing, but really nothing to do in
BLI_path_util files!

Also, got rid of length limitation in `BLI_uniquename_cb`, we can use
alloca here to avoid overhead of malloc while keeping free size (within
reasonable limits of course).
