dfc3ead10a MBR partition table support for wedges, enabled by the DKWEDGE_METHOD_MBR 
option.

1c2a2dcad3 move i/o schedulers to their own files. 
namely, from kern/subr_disk.c to kern/bufq_{fcfs,disksort,readprio,priocscan}.c.

563a66a36f Add a parsing module for 4.4BSD/NetBSD disklabels. This module supports 
disklabels nested inside an MBR "NetBSD" or "386BSD" partition (first
one found is considered authoritative for the disk), or in one of several
known locations for various NetBSD platforms.  It can read native or other-
endian disklabels (code is there, but not tested).

If you want to play with this, exercise caution; you can't currently
mountroot on a wedge (setroot() needs some work).  Enabled by the
DKWEDGE_METHOD_BSDLABEL kernel option.

27f0170634 Break out the wedge discovery methods into true modules, and add some 
infrastructure that allows new ones to be added.  The discovery methods
are prioritized, and only one can exist at a given priority.

The DKWEDGE_METHOD_GPT option causes GPT support to be included.  GPT is
at priority 0; we prefer GPT above all others.

11afd11faa Add a new VNODE_LOCKDEBUG option, which enables checks in the VOP_*() 
calls to ensure that the vnode lock state is as expected when the VOP
call is made.  Modify vnode_if.src to set the expected state according
to the documenting lock table for each VOP.  Modify vnode_if.sh to emit
the checks.

Notes:
- The checks are only performed if the vnode has the VLOCKSWORK bit
  set.  Some file systems (e.g. specfs) don't even bother with vnode
  locks, so of course the checks will fail.
- We can't actually run with VNODE_LOCKDEBUG because there are so many
  vnode locking problems, not the least of which is the "use SHARED for
  VOP_READ()" issue, which screws things up for the entire call chain.

Inspired by similar changes in OpenBSD, but implemented differently.

cbc396ce30 work around a binutils bug where converting ELF kernels to a.out with objcopy 
produces corrupted binaries when the link_set_* sections extend into another
page after the end of the .text section by using a generated an ldscript that
puts all the link_set_* data into the .text section in the first place.

1ce3b064a0 Make uudecode into a tool that can be used to build a kernel and redo 
the athhal-elf.o handling to take advantage of it.  This means that
bsd.files.mk is no longer included by Makefile.i386 so CFLAGS won't be
duplicated.

bfcdaa5766 PF from openbsd 3.5. missing features: 
- pfsync (due to protocol # assignment issues)
- carp (not really a PF portion, but thought important to mention)
- PF and ALTQ are mutually-exclusive.  this will be sorted out when
  kjc@csl.sony.co.jp updates ALTQ and PF (and API inbetween)

9b2972c08e Invert the meaning of SYSCTL_NO_DESCR by calling it SYSCTL_USE_DESCR

opposed to an option to *exclude* them.

1e239fdec9 Create opt_sysctl.h which will hold sysctl related options. I suspect 
most of these won't be used (well, the description related one will
be), but it's good to formalize things.
