*	Split 4.x and 5.x signal handling so that we can keep 4.x signal	Peter Wemm	2002-10-25	1	-4/+6
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	handling clean and functional as 5.x evolves. This allows some of the nasty bandaids in the 5.x codepaths to be unwound. Encapsulate 4.x signal handling under COMPAT_FREEBSD4 (there is an anti-foot-shooting measure in place, 5.x folks need this for a while) and finish encapsulating the older stuff under COMPAT_43. Since the ancient stuff is required on alpha (longjmp(3) passes a 'struct osigcontext ' to the current sigreturn(2), instead of the 'ucontext_t ' that sigreturn is supposed to take), add a compile time check to prevent foot shooting there too. Add uniform COMPAT_43 stubs for ia64/sparc64/powerpc. Tested on: i386, alpha, ia64. Compiled on sparc64 (a few days ago). Approved by: re Notes: svn path=/head/; revision=105950
*	Use struct __ucontext in prototypes and associated functions instead of	Daniel Eischen	2002-02-17	1	-3/+5
\| \| \| \| \| \| \| \| \| \| \| \| \|	ucontext_t. Forward declare struct __ucontext in <sys/signal.h> and remove reliance on <sys/ucontext.h> being included. While I'm here, also hide osigcontext types from userland; suggested by bde. Namespace pollution noticed by: Kevin Day <toasty@shell.dragondata.com> Notes: svn path=/head/; revision=90776

	----------------------------- By introducing a new sigframe so that the signal handler operates on the new siginfo_t and on ucontext_t instead of sigcontext, we now need two version of sendsig and sigreturn. A flag in struct proc determines whether the process expects an old sigframe or a new sigframe. The signal trampoline handles which sigreturn to call. It does this by testing for a magic cookie in the frame. The alpha uses osigreturn to implement longjmp. This means that osigreturn is not only used for compatibility with existing binaries. To handle the new sigset_t, setjmp saves it in sc_reserved (see NOTE). the struct sigframe has been moved from frame.h to sigframe.h to handle the complex header dependencies that was caused by the new sigframe. NOTE: For the i386, the size of jmp_buf has been increased to hold the new sigset_t. On the alpha this has been prevented by using sc_reserved in sigcontext. Notes: svn path=/head/; revision=51792
