Bug 1085024

After a redhat audit we send a dozen bugs upstream. 1.7.2.3 fixed the CVE issue that was found. All other bugs did not make it in, but we have bug entries for these. Since there are also a dozen other fixes, we should just rebase, or else we just end up with 1.7.2.4 calling itself 1.7.2.3. Relevant part of http://www.dest-unreach.org/socat/doc/CHANGES listed below which contain our bugzilla references

corrections:
	LISTEN based addresses applied some address options, e.g. so-keepalive,
	to the listening file descriptor instead of the connected file
	descriptor

	make failed after configure with non gcc compiler due to missing
	include. Thanks to Horacio Mijail for reporting this problem

	configure checked for --disable-rawsocket but printed
	--disable-genericsocket in the help text. Thanks to Ben Gardiner for
	reporting and patching this bug

	In xioshutdown() a wrong branch was chosen after RECVFROM type addresses.
	Probably no impact.
	Thanks to David Binderman for reproting this issue.

	procan could not cleanly format ulimit values longer than 16 decimal
	digits. Thanks to Frank Dana for providing a patch that increases field
	width to 24 digits.

	On big endian platforms with type long >32bit the range option applied a
