sm: Use estream for I/O.

* sm/decrypt.c (gpgsm_decrypt): Use estream for the input.
* sm/encrypt.c (gpgsm_encrypt): Likewise.
* sm/gpgsm.c (open_read): Remove.
(main): Use open_es_fread for gpgsm_import_files.  Fix call of
gpgsm_encrypt, gpgsm_sign, gpgsm_verify and gpgsm_decrypt.
(open_es_fread): Use gnupg_check_special_filename and open_stream_nc.
* sm/gpgsm.h: Fix function declarations.

(reimport_one, gpgsm_import, gpgsm_import_files): Likewise.
* sm/server.c (struct server_local_s): Rename MESSAGE_FD to
MESSAGE_FP.
(close_message_fp): Rename from close_message_fd.
(reset_notify): Follow the change of close_message_fp.
(cmd_encrypt, cmd_decrypt, cmd_verify, cmd_sign): Follow the change of
close_message_fp.  Use open_stream_nc to get estream.
(cmd_import): Likewise.
(cmd_export, cmd_delkeys, gpgsm_server): Follow the change of
close_message_fp.
(cmd_message): Setup MESSAGE_FP with open_stream_nc.
* sm/sign.c (hash_data): Use estream for the input.
(hash_and_copy_data): Likewise.
(gpgsm_sign): Likewise.
* sm/verify.c (hash_data): Use estream_t for FP.
(gpgsm_verify): Use estream_t for IN_FP and DATA_FP.
