e9e91a0fb5 split off thread specific stuff from struct sigacts to struct sigctx, leaving 
only signal handler array sharable between threads
move other random signal stuff from struct proc to struct sigctx

This addresses kern/10981 by Matthew Orgass.

f495cd9dc6 Introduce 2 new flags in types.h: 
* __HAVE_SYSCALL_INTERN.  If this is defined, e_syscall is replaced by
  e_syscall_intern, which is called at key places in the kernel.  This can be
  used to set a MD syscall handler pointer.  This obsoletes and replaces the
  *_HAS_SEPARATED_SYSCALL flags.
* __HAVE_MINIMAL_EMUL.  If this is defined, certain (deprecated) elements in
  struct emul are omitted.

probably due to bad frame setup
it's not possible to setup breakpoints - Linux gdb uses hw breakpoints,

baae0324b9 restructure struct emul and execsw, in preparation to make emulations LKMable: 
* move all exec-type specific information from struct emul to execsw[] and
  provide single struct emul per emulation
* elf:
  - kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry
    per emulation and contains pointer to respective probe function
  - interp is allocated via MALLOC() rather than on stack
  - elf_args structure is allocated via MALLOC() rather than malloc()
* ecoff: the per-emulation hooks moved from alpha and mips specific code
  to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per
  emulation supporting ecoff with appropriate probe function
* the makecmds/probe functions don't set emulation, pointer to emulation is
  part of appropriate execsw[] entry
* constify couple of structures

f96aee80d6 Make the linux compatibilty code work on the alpha. (horay!) (at last!) 
Two main changes:
	Create a linux_elf64_copyargs that uses the linux specific LinuxAuxInfo
	structure.  This is only used on the alpha.  i386 and m68k use the
	standard elf copyargs function.

	Since linux's approach to binary compatibilty is to look as much
	like osf1 as possible, add all the osf1 syscalls that we have
	implemented to the linux syscall table.  This includes get/setsysinfo,
	ported from FreeBSD.

In order for linux compat to work you must have COMPAT_OSF1, COMPAT_43,
COMPAT_09, COMPAT_12 and COMPAT_13 on also.

neither should the linux compatibility code.

Removing this is necessary to keep linux X server emulation functionining
after GENERIC rev 1.337 removing "options XSERVER" (relegating it
to the pccons/pcvt-specific, and therefore depricated).

fb526e055c Substantial signal handling changes: 
* Increase the size of sigset_t to accomodate 128 signals -- adding new
  versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and
  sys_sigsuspend() to handle the changed arguments.
* Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(),
  sys_sigpending() and sys_sigsuspend() into separate functions, and call them
  from all the emulations rather than hard-coding everything.  (Avoids uses
  the stackgap crap for these system calls.)
* Add a new flag (p_checksig) to indicate that a process may have signals
  pending and userret() needs to do the full (slow) check.
* Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE.
* Correct emulation bugs with restoring SS_ONSTACK.
* Make the signal mask in the sigcontext always use the emulated mask format.
* Store signals internally in sigaction structures, rather than maintaining a
  bunch of little sigsets for each SA_* bit.
* Keep track of where we put the signal trampoline, rather than figuring it out
  in *_sendsig().
* Issue a warning when a non-emulated sigaction bit is observed.
* Add missing emulated signals, and a native SIGPWR (currently not used).
* Implement the `not reset when caught' semantics for relevant signals.

Note: Only code touched by the i386 port has been modified.  Other ports and
emulations need to be updated.
