Andrew Gallatin 931a725809 This is the first of 3 commits that will get IBM's JDK 1.3 working 
with FreeBSD (not including the MINSIGSTKSZ issue, which belongs to
Marcel).  Due to time constraints, I'm going to space them out over a
few days.

This fixes two problems with linux_sigaltstack()

o ss == 0 is perfectly valid use, so do not fail in this case.

o Fix flag handling:
 - Our SS_DISABLE is 4, linux's is 2, so we need conversion routines.
	These conversion routines will be needed by linux_rt_sendsig()
	and linux_rt_sigreturn (forthcoming), so they are not static.
 - Linux's flag 0 historically meant SS_ONSTACK according to a comment
	in their linux/kernel/signal.c file.

Among other things, this fixes a warning from Sun's JDK 1.3:
"Java HotSpot(TM) Client VM warning: cannot uninstall alt signal stack"
