gpg: Prepare for a longer fingerprint

Browse source 
* g10/card-util.c (change_cafpr): Use MAX_FINGERPRINT_LEN.
* g10/cipher.c (write_header): Use snprintf.
* g10/gpg.h (MAX_FINGERPRINT_LEN): Change to 32.
(MAX_FORMATTED_FINGERPRINT_LEN): Change to 59
* g10/keyid.c (format_hexfingerprint): Add v5 fingerprint format.
* g10/tofu.c (get_policy): Use MAX_FINGERPRINT_LEN for the buffer but
keep the raw length for now.
--

Note that this patch only increases the size of the buffer and adds a
new formatting for v5 fingerprints.  Moe work is required to fix
internal data structures like those in trustdb.gpg and the tofu
tables.
