libpayload update

* rework Config.in
* add string_to_args function to actually make getopt usable.
* add strchr
* add strlcat
* some malloc fixes (exposed by the USB stack)
* add malloc debugging (thanks to Matthias Krause from Secunet!)
* make LAR support optional, it's not really used anymore
* (define htoX macros for ppc)
