28 * Inflate all files under zip_path to the directory specified by

31 * will be extracted.

33 * Directory entries are not extracted.
34 *
35 * The immediate children of zip_path will become the immediate
36 * children of dest_path; e.g., if the archive contains the entries
37 *
38 * a/b/c/one
39 * a/b/c/two
40 * a/b/c/d/three

42 * and ExtractPackageRecursive(a, "a/b/c", "/tmp", ...) is called, the resulting
43 * files will be
44 *
45 * /tmp/one
46 * /tmp/two
47 * /tmp/d/three
48 *
49 * If timestamp is non-NULL, file timestamps will be set accordingly.
50 *
51 * Returns true on success, false on failure.
