scd:piv: Implement PIN cache.
* scd/command.c (pincache_put): Add arg pinlen and change all callers
to provide it.
* scd/app-piv.c (cache_pin): New.
(pin_from_cache): New.
(ask_and_prepare_chv): Add args no_cache and r_unpaddedpinlen. Take
PIN from the cache. Return the unpadded length.
(verify_chv): Add arg ctrl. Cache the PIN.
(do_change_chv): Clear PIN cache.
--
The PIV pins are padded but we want to store the unpadded PIN. Thus
the changes to the function.
Code has has been tested by commenting the no_cache parameter because
we the current test certificate was created for PIV.9C which requires
a verification for each use. More testing is required.
