* helper functions for path strings.

// notes:
// - this module is independent of lib/file so that it can be used from
// other code without pulling in the entire file manager.
// - there is no restriction on buffer lengths except the underlying OS.
// input buffers must not exceed PATH_MAX chars, while outputs
// must hold at least that much.
// - unless otherwise mentioned, all functions are intended to work with
// native and VFS paths.
// when reading, both '/' and SYS_DIR_SEP are accepted; '/' is written.
