all platforms, kernel: remove __HAVE_CLOCKINTR symbol

Every platform made the clockintr switch at least six months ago.
The __HAVE_CLOCKINTR symbol is now redundant. Remove it.

#define _MAX_PAGE_SHIFT in MD _types.h as the maximum pagesize an arch
needs (looking at you sgi, but others required this before). This is for
the circumstances we need pagesize known at compile time, not getpagesize()
runtime. Use it for malloc storage sizes, for shm, and to set pthread stack
default sizes. The stack sizes were a mess, and pushing them towards
page-aligned is healthy move (which will also be needed by the coming
stack register checker)

It's safe to assumed 'signed' exists

Provide MI symbol _STACKALIGNBYTES

unify register_t to long on all platforms

Take II, this time without flubbing off_t: : move several internal
type definitions that are the same across all archs from
<machine/_types.h> to <sys/_types.h>

ok deraadt@ kettenis@ otto@

backout previous; off_t must be signed and there might be other C++ API
breakage lurking; ok kettenis@

To ease future changes, move several internal type definitions that are
the same across all archs from <machine/_types.h> to <sys/_types.h>

unifdef -D __HAVE_TIMECOUNTER

Switch landisk to timecounters. Adapted from NetBSD.

label_t is the kernel setjmp buffer. It should simply be an array of
the right type, noone will ever fiddle with the internals.

Get rid of __HAVE_GENERIC_SOFT_INTERRUPTS now that all our platforms support it.

- add proper double_t and float_t definitions for each arch
- math.h shouldn't define FLT_EVAL_METHOD, but float.h should (per
C99). remove from math.h, and add proper definitions in float.h

The world of __HAVEs and __HAVE_NOTs is reducing. All architectures
have cpu_info now, so kill the option.

eyeballed by jsg@ and grange@

Remove the MI implementation of mutexes and remove the __HAVE_MUTEX
option. Every architecture implements mutexes now.

Switch sh to __HAVE_CPUINFO. The least possible effort for now.

deraadt@ ok

Simple monoprocessor mutex implementation, faster than the MI code, four left
to go.

Preliminary bits for SuperH-based ports, based on NetBSD/sh3 codebase with
minor changes.
