related afaics, this is harmliss for now since
netbsd32 doesn't support multithreaded programs yet --
one day one execve() implementation should be shared
by native and netbsd32 code.

Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

struct proc * -> struct lwp *

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records. The general change has been to replace

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

Merge the nathanw_sa branch.

p->p_sigacts -> p->p_sigctx

Implement passing AT_{E,R}{U,G}ID in the elf aux vector, like solaris.
- pass struct proc to copyargs.
- eliminate svr4_copyargs, since it is the same as ours now.

Fix some signed/unsigned comparison warnings from GCC 3.3.

Fix wrong psstr computation.
(XXX why is there an entire copy of sys_execve here?)

invoke setregs hooks correctly, as in sys_execve()
Problem noted and fix tested by Eduardo Horvath

make the stackgap_{init,alloc} functions MP friendly (i.e. pass struct proc *
in, instead of using curproc). While there add an optional size argument to
stackgap_init.

In check_exec(), don't bother checking P_TRACED along with

In check_exec(), don't bother checking P_TRACED along with
MNT_NOSUID, just check MNT_NOSUID to clear the S{U,G}ID bits
in the attributes for the vnode we're about to exec.

We now check P_TRACED right before we would actually perform
the s{u,g}id function in the exec code.

This closes a race condition between exec of a setuid binary
and ptrace(2).

split up netbsd32_netbsd.c into 9 new files, leaving only those syscalls that
have no special interpretations besides simple syscall args conversion.
