	* gpgme.texi (Passphrase Callback): Document new prototype.

	* engine.h (EngineCommandHandler): Change last argument to int fd.
	* gpgme.h (gpgme_passphrase_cb_t): Rewritten to take parts of the
	description and fd.
	(gpgme_edit_cb_t): Change last argument to int fd.
	* ops.h (_gpgme_passphrase_command_handler_internal): New prototype.
	* passphrase.c: Include <assert.h>.
	(op_data_t): Rename userid_hint to uid_hint, remove last_pw_handle.
	(release_op_data): Check values before calling free.
	(_gpgme_passphrase_status_handler): Likewise.
	(_gpgme_passphrase_command_handler_internal): New function.
	(_gpgme_passphrase_command_handler): Rewritten.
	* edit.c (edit_status_handler): Pass -1 as fd argument.
	(command_handler): Update prototype.  New variable processed.  Use
	it to store return value of
	_gpgme_passphrase_command_handler_internal which is now used
	instead _gpgme_passphrase_command_handler.  Use it also to check
	if we should call the user's edit function.  Pass fd to user's
	edit function.
	* rungpg.c (struct gpg_object_s): Change type of cmd.cb_data to
	void *.
	(gpg_release): Check value before calling free.  Do not release
	cmd.cb_data.
	(command_cb): Function removed.
	(command_handler): New function.  Thus we don't use a data object
	for command handler stuff anymore, but handle it directly.  This
	allows proper error reporting (cancel of passphrase requests, for
	example).  Also all callbacks work via direct writes to the file
	descriptor (so that passphrases are not kept in insecure memory).
	(gpg_set_command_handler): Rewritten to use even more ugly hacks.
	(read_status): Check cmd.keyword before calling free.  Install
	command_handler as the I/O callback handler with GPG as private
	data.

	* (t-decrypt-verify.c, t-decrypt.c, t-edit.c, t-encrypt-sign.c,
	t-encrypt-sym.c, t-sign.c, t-signers.c): Include <unistd.h>.
	(passphrase_cb): Rewritten.
	* t-edit.c (edit_fnc): Rewritten.
