gpg: Change sqlite3_stepx to pass the sqlite3_stmt * to the callback.

Browse Source 
* g10/sqlite.h (enum sqlite_arg_type): Add SQLITE_ARG_BLOB.
(sqlite3_stepx_callback): New declaration.
(sqlite3_stepx): Change the callback's type to sqlite3_stepx_callback,
which passes an additional parameter, the sqlite3_stmt *.  Update
users.
