gpg: Use gnupg_fd_t for decryption and sign.

Browse Source 
* g10/decrypt.c (decrypt_message_fd): Use gnupg_fd_t.
* g10/plaintext.c (hash_datafile_by_fd): Use  gnupg_fd_t.
* g10/main.h: Fix the declarations.
* g10/mainproc.c (struct mainproc_context): Use gnupg_fd_t for
DATA_FD.
(proc_compressed_cb, proc_signature_packets): Follow the change.
(proc_signature_packets_by_fd): Use gnupg_fd_t.
* g10/packet.h: Fix the declaration.
