Fix memory leak.
Add convenience option for cross build to amd64

Also enhanced libassuan-config and libassuan.m4.
Not really tested!

(At least with the forthcoming gnupg 1.9.91)

	* assuan-client.c (assuan_transact): Do not convert error on
	status line, it is already a gpg-error.  Do convert
	ASSUAN_Server_Fault.

	* assuan.h (assuan_init_socket_server_ext)
	[_ASSUAN_EXT_SYM_PREFIX]: Fix typo in macro.

platforms.

	* tests/fdpassing.c (MOTD): New macro.
	* tests/Makefile.am (AM_CPPFLAGS): New variable.
	* tests/motd: New file.

	* assuan-pipe-connect.c: Add hacks for Slowaris.
	* assuan-socket.c: Likewise here.

	* assuan.h (enum): Avoid trailing comma in enumerator list.  Ugh.

	* mkerrors (_assuan_error): Change return type to assuan_error_t.
	* assuan-buffer.c (_assuan_read_line): Change return type to
	assuan_error_t.  Map returned value of -1.
	(_assuan_write_line): Change type of RC to assuan_error_t.
	* assuan-defs.h (_assuan_read_line, _assuan_error): Likewise for
	prototypes.

	* assuan-defs.h (unsetenv): Define correctly.

gpg-connect-agent may now be used as a test program.

	* configure.ac: Check for socket library and add it to
	LIBASSUAN_CONFIG_LIBS if necessary.

	* assuan-defs.h (setenv, unsetenv, clearenv) [!HAVE_SETENV]:
	Define to _assuan_*.
	* setenv.c: Include "assuan-defs.h".
	(__add_to_environ): Make static.

	* configure.ac: Invoke AC_CANONICAL_HOST.  Define _XOPEN_SOURCE,
	_XOPEN_SOURCE_EXTENDED and __EXTENSIONS__ on Solaris.
	Add stpcy as replacement function.
	Add setenv as replacement function (and check for unistd.h).
