Log Message:
Update socat to 1.7.1.2

Changelog:

corrections:
	user-late and group-late, when applied to a pty, affected the system
	device /dev/ptmx instead of the pty (thanks to Matthew Cloke for
	pointing me to this bug)

	socats openssl addresses failed with "nonblocking operation did not
	complete" when the peer performed a renegotiation. Thanks to Benjamin
	Delpy for reporting this bug.

	info message during socks connect showed bad port number on little
	endian systems due to wrong byte order (thanks to Peter M. Galbavy for
	bug report and patch)

	Debian bug 531078: socat execs children with SIGCHLD ignored; corrected
	to default. Thanks to Martin Dorey for reporting this bug.

porting:
	building socat on systems that predefined the CFLAGS environment to
	contain -Wall failed (esp.RedHat). Thanks to Paul Wouters for reporting
	this problem and to Simon Matter for providing the patch

	support for Solaris 8 and Sun Studio support (thanks to Sebastian
	Kayser for providing the patches)

	on some 64bit systems a compiler warning "cast from pointer to integer
	of different size" was issued on some option definitions

	added struct sockaddr_ll to union sockaddr_union to avoid "strict
	aliasing" warnings (problem reported by Paul Wouters)
