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.
