gpg: Do not allow creation of user ids larger than our parser allows.
* g10/parse-packet.c: Move max packet lengths constants to ... * g10/packet.h: ... here. * g10/build-packet.c (do_user_id): Return an error if too data is too large. * g10/keygen.c (write_uid): Return an error for too large data.
This can lead to keyring corruption becuase we expect that our parser
is abale to parse packts created by us. Test case is
gpg --batch --passphrase 'abc' -v \ --quick-gen-key $(yes 'a'| head -4000|tr -d '\n')
