This function is intended as a more general version of gpg's
pubkey_string function. It has the advantage to avoid mallocs and
uses static table of algorithm strings instead. There should be only
a few dozen of such strings (if at all) and thus all those allocations
we do internally in gpg's pubkey_string and the static buffers all
over the place are not too nice.

This option can be used by clients who can only provide a DER encoded

Testing:
Put the DER encoded issuer DN into a file, say issuer.der.
The run
gpg-connect-agent -E -- gpgsm --server
> /definqfile ISSUER_DER issuer.der
> list-keys --issuer-der 01020304
and if the local keyring has a certifictate with that issuer and a s/n
of 0x01020304 that certificate will be listed.

The PIV pins are padded but we want to store the unpadded PIN. Thus
the changes to the function.

This cache speeds up processing of commands like "gpg -K" because

bit course but sufficient.

(do_sign): Do not cache the PIN here.
--
Note that some of the changes are required because we can't rely that
the PIN is always cached in secure memory. Thus it is better to do an
explicit wipe.
Testing the PIN cache can currently only be done my modifying the
code to do a verification for each operation. Only some basic testing
has been done. Clearing the PIN cache is also not fully
implemented. With the forthcoming changes to app-piv we should be
enter able to test the PIN cache.
Missing stuff:
- The agent should be able to selectively clear the cache on a per
slot base.
- We should replace AESWRAP by OCB.

This change does away with encrypting and decrypting the cached PIN in
the agent. There is no need for this we can simply cache the
cryptogram and let scdaemon decrypt after retrieving it from the
agent. This way we do not need to share a key between gpg-agent and
scdaemon and further the cached content is invalid after the scdaemon
process has been replaced.
