* g10/keyring.c (keyring_get_keyblock): Whitelist allowed packet
types.
* g10/keydb.c (parse_keyblock_image): Ditto.
--
The keyring DB code did not reject packets which don't belong into a
keyring. If for example the keyblock contains a literal data packet
it is expected that the processing code stops at the data packet and
reads from the input stream which is referenced from the data packets.
Obviously the keyring processing code does not and cannot do that.
However, when exporting this messes up the IOBUF and leads to an
invalid read of sizeof (int).
We now skip all packets which are not allowed in a keyring.

The idea with this change is that under Windows we can install a
simple native Windows pinentry as "pinentry-basic" and a full GUI
version may then later install pinentry-gtk etc which would then
automatically be used.
Unfortunately installing another pinentry from a different package
would clobber the GnuPG core directory which is not nice. To fix that
we would need to agree on standard installation directories for GUIs
to also look there.

Without that it is possible to force gpg to allocate large amounts of
memory by using a bad encoded MPI. This would be an too easy DoS.
Another way to mitigate would be to change the MPI read function to
allocate memory dynamically while reading the MPI. However, that
complicates and possibly slows down the code. A too large key packet
is in any case a sign for broken data and thus gpg should not use it.
