Just in case of uninitialized padding which would lead to kernel stack disclosure. If the compiler can prove the memset redundant then it can optimize it away; otherwise better safe than sorry.

Convert all the system call entry points from: int foo(struct lwp *l, void *v, register_t *retval) to: int foo(struct lwp *l, const struct foo_args *uap, register_t *retval) Fixup compat code
Convert all the system call entry points from: int foo(struct lwp *l, void *v, register_t *retval) to: int foo(struct lwp *l, const struct foo_args *uap, register_t *retval) Fixup compat code to not write into 'uap' and (in some cases) to actually pass a correctly formatted 'uap' structure with the right name to the next routine. A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.

Change the way that emulations locate files within the emulation root to avoid having to allocate space in the 'stackgap' - which is very LWP unfriendly. The additional code for non-emulation namei() is trivial, the reduction for the emulations is massive. The vnode for a processes emulation root is saved in the cwdi structure during process exec. If the emulation root the TRYEMULROOT flag are set, namei() will do an initial search for absolute pathnames in the emulation root, if that fails it will retry from the normal root. ".." at the emulation root will always go to the real root, even in the middle of paths and when expanding symlinks. Absolute symlinks found using absolute paths in the emulation root will be relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links inside the emulation root don't need changing). If the root of the emulation would be returned (for an emulation lookup), then the real root is returned instead (matching the behaviour of emul_lookup, but being a cheap comparison here) so that programs that scan "../.." looking for the root dircetory don't loop forever. The target for symbolic links is no longer mangled (it used to get the CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended). CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding TRYEMULROOT to the flags to NDINIT(). A lot of the emulation system call stubs could now be deleted.

remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.

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.

In preparation for COMPAT_NETBSD32 on SH-5:
- The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp().
