//
// Arguments | JoinPath
// ---------------------------+---------------------
// '/foo', 'bar' | /foo/bar
// '/foo/', 'bar' | /foo/bar
// '/foo', '/bar' | /foo/bar
// '/foo', '/bar', '/baz' | /foo/bar/baz
//
// All paths will be treated as relative paths, regardless of whether or not
// they start with a leading '/'. That is, all paths will be concatenated
// together, with the appropriate path separator inserted in between.
// Arguments must be convertible to port::StringPiece.
//
// Usage:
// string path = file::JoinPath("/var/log", dirname, filename);
// string path = file::JoinPath(FLAGS_test_srcdir, filename);
