bouyer dc306354b0 Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.

thorpej ec897ee047 Fix a problem reported by Michael Hitch. Basically, our libc relies on the
non-standard way of invoking sigreturn, specifically a side-effect that I
overlooked.  Thus, longjmp's return value was getting clobbered.

Sigh, so burn trap #3 just as sigreturn.

XXX trap vectors in the future.

cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

- fix __indr_reference and __warn_references so that they
  supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
  by the way it's used).

The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.

error handling in the 060 support code.
This is repaired by jumping to _buserr60 from the 060SP, and by providing
a _buserr60 label identical to the _buserr in the unchanged m68k ports
using the 68060.

is 6d6e724440 Reorganize buserr/addrerr stuff, to allow omitting unused code in single-cpu
kernels, at the same time getting rid of up to 3 conditional branches and a
bit over one cacheline fetch (for the 68060; the saving is a bit smaller for
040 and yet smaller for the 020/30).
While we're here, also get rid of an redundant lea (using SP-relative
addressing) and of two redundant pushes.
While we're here, also fix a panic which would tear us down on 68060 machines
if a branch prediction error ever occured.

jtc 9d04fc8ed1 New zeropage() implementation based on code contributed by Hiroshi Horitomo
<horimoto@cs-aoi.cs.sist.ac.jp> in PR #3641.   I changed the code slightly.
Instead of clearing 13 registers (d1-d7,a1-a6) and zeroing 512 bytes per
loop iteration, I clear 8 registers (d1-d7,a1) and zero 256 bytes.  This
reduces the size and complexity of the function.

On the '020, the simpler code is less than 1% slower.  Surprisingly, it
is ~3% faster on the '040.

- GLOBAL()/ASGLOBAL() and LOCAL()/ASLOCAL(), for defining global and
  local variables with C and ASM labels.
- BSS()/ASBSS(), for defining items in the BSS segment, with C or
  ASM labels.
- PANIC("panic message") - shorthand for calling panic() from assembly code.
- VECTOR(), ASVECTOR(), VECTOR_UNUSED - shorthand for defining entries
  in the vector table.
Also, change RCSID() to pad out the string to even boundary.
