gpg: Rename struct pubkey to pukey_s and add pubkey_t.
* g10/keydb.h (struct pubkey): Rename to pubkey_s. (pubkey_t): New. Change all struct pubkey_s to use this type. * g10/getkey.c (get_pubkeys): Rename arg keys to r_keys.
It is common in GnuPG to use a suffix of _s for struct names. There
is no technical need for this (actually this pattern comes from pre
ANSI C compilers which had no separate namespaces) but it avoid
surprises when reading the code.
Adding the pubkey_t type is mainly to improve font locking by using
the common suffix _t for a typedefed type.
