Subject: [PATCH] gpg: Use gnupg_fd_t for iobuf_get_fd and is_secured_file.

* common/iobuf.c (iobuf_get_fd): Return type is now gnupg_fd_t.
* common/iobuf.h (iobuf_get_fd): Fix the return type.
* g10/misc.c (is_secured_file): Argument is now gnupg_fd_t.
* g10/main.h (is_secured_file): Fix the argument type.
