option and route header parsing. This checkin marks the older APIs
as deprecated and points the reader to the newer pages.

The old ldexp() implementation...

a minimal "untar" program using libarchive can now be

using library *printf() functions).

* Correctly step through the directory records
(skipping unrecognized extensions)
* Use better defaults for file modes
* Sort directory entries by offset of the end of the file

in particular.
* Style fixes, remove some debug code, add some error messages.
