af14995e51 Create a shared set of ARM sources for libkern and move arm26 over to using
them.

These are identical to the current arm32 sources with the following exceptions:
 - References to C labels are wrapped in _C_LABEL().
 - Function returns have an alternate version inside #ifdef __APCS_26__.

2dc247fc34 make CMSG_ALIGN always synchronize with kernel's idea of ALIGNBYTES.
ancillary data alignment will be ALIGNBYTES, not sizeof(long) - 1, from now.

CMSG_xx will NOT resolve into constant.  if you use CMSG_xx to allocate
arrays, you'll lose.

bump shlib minor for libc.

NOTE: if you are on top of arch with ALIGNBYTES != sizeof(long) - 1,
you need to recompile IPv6-related binaries.  there is no way to guarantee
backward compat in this aspect.  sorry for this.  this should be the last
backward compat breakage for IPv6-related ancillary data manipulation.

Tree structure:

- sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW)
- sys/arch/mmeye: Brains mmEye, www.brains.co.jp
MI source code includes couple of #ifdef for sh3-coff support.

Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3,

192b3c733c Build libraries for kernel/standalone code from within their compilation
directories and use .PATH to lookup the source files.
(Formerly, the libs were built from the source dirs, with MAKEOBJDIR
set to the compilation directory.)
This solves 2 problems:
-"mkdep" and "make" are now consistent about the file lookup, this fixes
 bad interactions with amd reported in PR bin/7374 (Arne Juul) and
 lossage reported by Andrew Gillham ("obj" dirs and relative paths still
 don't work well together)
-kernel compile trees can be moved around without forcing a new
 "make depend" - fixing PR kern/4021 by Martin Husemann

4634c0e3d4 libkern just got an inet_addr(), but it won't compile, no prototype. Cleanup...
* Add prototype to libkern.h.
* Remove the almost-identical-copy from libsa/net.[ch].
* Change its type back to the (wrong, but harmless) historical one. (u_long)
* Kill the XXX local prototype in nfs_bootparam.c

309213477a Make a bunch of backward-compatible changes to the boot blocks which allow
size to be reduced substantially.  (backward compatibility verified
by compiling one of the alpha boot blocks which uses all of the code
before and after, diffing the object files, and manually verifying that
the differences were 'correct'.  some differences were "unavoidable,"
it wanting to avoid a double-commit, because e.g. local variables which
were previously used were no longer used.)  a README which describes
supported options (or at least the ones mentioned below) is forthcoming.

add support for the preprocessor macro LIBSA_NO_TWIDDLE, which
  causes calls to twiddle() to be omitted if it's defined.
add support for the preprocessor macros:
	LIBSA_NO_FS_CLOSE
	LIBSA_NO_FS_WRITE
	LIBSA_NO_FS_SEEK
  which, if defined, cause the corresponding file system operations
  in the individual file system implementations to be omitted.  (note
  that all of those macros are not supported by all file systems at
  this point.  comments were added to individual file system files
  to indicate lack of support, and should be cleaned up later.  Backward
  compatibility options e.g. UFS_NOCLOSE, etc., are supported.)
add support for the preprocessor macro LIBSA_NO_FS_SYMLINK, which
  removes support for symbolic links from the file system support
  functions.  (same notes as for the macros above apply.)
add support for the preprocessor macro LIBSA_FS_SINGLECOMPONENT which
  removes all subdirectory and symlink support from the file system
  support functions.  (same notes as for the macros above apply.)
add support for the preprocessor macro LIBSA_NO_FD_CHECKING, which
  causes code relating to libsa file descriptor checks (e.g. range
  checking and checking that a file descriptor is valid) to be
  omitted if it's defined.
add support for the preprocessor macro LIBSA_NO_RAW_ACCESS, which
  causes code relating to raw device access to be omitted if it's
  defined.
change some structure copies to use bcopy() instead.  that way
  use of bcopy vs. memcpy() can easily be selected by
  LIBSA_USE_MEMCPY.  (without changes like these, you could end up
  having both bcopy() and memcpy() included.  eventually, all
  calls to bcopy should be changed to calls to memcpy() or memmove()
  as appropriate -- hopefully never the latter -- with an option to
  use bcopy instead.)
add support for the preprocessor macro LIBSA_NO_DISKLABEL_MSGS, which
  causes disklabel() to return '1' as msg rather than a string.  Can
  be used if the boot blocks don't care about the string, and need to
  save the space.
add support for the preprocessor macro LIBSA_SINGLE_FILESYSTEM, which
  if defined causes all of the file system switch code to be removed.
  Its value should be the name of the file system supported by the
  boot block, e.g. "ufs" for the FFS file system.  calls to the
  file system functions open, close, etc., which were previously
  done through a function switch are then done via direct invocation
  of <fs>_open, <fs>_close, etc. (e.g. ufs_open, ...).
add support for the preprocessor macro LIBSA_SINGLE_DEVICE, which
  does the equivalent of LIBSA_SINGLE_FILESYSTEM but for the device
  switch table.  Device entry pointes are expected to be named
  <dev>foo, e.g. the 'strategy' routine used when LIBSA_SINGLE_DEVICE
  is set to 'disk' is diskstrategy.
make ufs.c f_nindir array be unsigned ints.  the fact that it was signed
  caused ufs.c to require signed division routines (which were otherwise
  unnecessary for a small boot block).
