SF Patch Tracker [ 2836704 ] Patch for Solaris10 compilation and usage.

Submitted By: zephyrus ( zephyrus00jp )
	Obs by Marcelo: The issue with linking with -lsocket -lnsl -lrt is not
	covered in this changeset beacuse I don't have solaris to test. I will
	need some help from zephyrus in this regard. The issue will be addressed
	in a future changeset.

	Compilation for solaris

	I have used gcc3.x and gcc4.x under solaris 10 for x86 / 64 bits.

	A couple of Source file fixes were necessary for successful compilation
	and runtime behavior.

	threadutil/src/ThreadPool.c

	POSIX
	sched_setschduler() returns non-negative value for success.

	Without the fix, UpnpInit() fails immediately.

	upnpp/src/api/upnpai.c

	There is a typo of a macro name "__sun" in one of the
	CPP conditional.
	Without the fix, the compilation aborts due to unknown constant
	in socket ioctl call.

	A few structs and an array is not properly initialized.
	Well, I think it may be safe as is, but when I checked it
	using purify evaluation version, it was reported that
	uninitizlied iszBuffer may cause read of uninitialized memory.
	So play it safe.

	Configure issue.
	This has to be more of a configure magic.
	To link a program successfully using network, we need
	-lsocket and -lnsl library specifications on the link line.
	We also need -lrt for programs that use thread scheduling features.

	The sample program under upnp/sample requires
	-lsocket -lnsl -lrt
	for successful linking.
	I added -lsocket -lnsl -lrt to Makefile.in.
	configure probably needs to take care of these.

	I don't know much about configure, automake, etc., so
	I am just raising a flag here.

	TIA
