Compile-out support for allfreebsd, dedicate, sanitize and bios on
ia64. These commands are PC specific and not supported.
Do not fill in d_ncylinders, d_ntracks and d_nsectors in the disklabel
on ia64. Not only do we not have a disklabel by default, we also do
not have a notion of cylinders, tracks and sectors.
o  Move Int_Open_Disk() from disk.c to open_disk.c for use by all
   platforms except ia64 and use Int_Open_Disk() in open_ia64_disk.c
   on ia64. We need to know more than GEOM can provide us so we're
   forced to read from the disk. Move uuid_type() to open_ia64_disk.c
   and remove all references on non-ia64.
o  Pass the GEOM conftxt to Int_Open_Disk() so that only Open_Disk()
   needs to know about GEOM and libdisk can more easily be used with
   media not handled by GEOM.
o  Create an ia64 specific definiton of struct disk on ia64, because
   we don't need/have most of the fields other platforms need and
   other fields not applicable on platforms other than ia64.
o  Do not compile change.c on ia64. It's too PC specific.
o  In Fixup_Names() in create_chunk.c, try all partition numbers
   that are valid for the GPT disk. We have the total number of
   partitions that can be allocated in the disk structure on ia64.
   Also, use the GPT partition naming if we're creating one under
   a chunk of type "whole". It's a GPT partition in that case.
o  In Create_Chunk(), compile-out the PC specific code on ia64 that
   checks BIOS geometry restrictions.
o  In Debug_Disk() in disk.c, dump the ia64 specific fields.
o  Save the partition index in the chunk on ia64 so that we can
   preserve it when we write the data back to disk. This avoids that
   partitions get moved around or swapped after installing FreeBSD,
   which may render a disk unusable.
Turn Write_Disk() into a stub for now. It needs to be rewritten to
write out a GPT and not a MBR.
o  Add PART_EFI so that we can use it instead of PART_FAT on ia64
   to better deal with the fact that we need an EFI partition and
   that we need to have a mountpoint for it.
o  When creating a new partition, add EFI to the list of types
   the user can select from. This makes it easy to create an EFI.
o  Do not include wizard.c on ia64.
o  The user cannot create a partition on ia64 that's a multiple of
   the cylinder size. We don't have a notion of cyclinders.
- do not quit from key_sendup() even if writes to non-target
  socket fails.
- remove an unneeded function.
- fix pfkey stat.
- fix comment.

Remove headers copied from i386 and either useless or wrong on ia64.
An example of useless is bios.h. An example of wrong is msdos.h (due
to the use of long for 32-bit fields).

display.h cannot be removed because it's used by syscons. That header
however has no platform dependency and shouldn't really be here.

Removal if these headers may cause build failures in the ports tree.
It's the ports that need fixing in that case.

Tested with: buildworld, LINT
Convert the Big5, EUC, MSKanji and UTF-8 encoding methods to implement
mbrtowc() and wcrtomb() directly. GB18030, GBK and UTF2 are left
unconverted; GB18030 will be done eventually, but GBK and UTF2 may just
be removed, as they are subsets of GB18030 and UTF-8 respectively.
cleanup secasvar management; refcnt is key.c responsibility;
alloc/free is keydb.c responsibility.

Make sure we get all user-written input. This simplifies the

 - Remove the ksq_loads[] array.  We are only interested in three counts,
   the total load, the timeshare load, and the number of threads that can
   be migrated to another cpu.  Account for these seperately.
 - Introduce a KSE_CAN_MIGRATE() macro which determines whether or not a KSE
   can be migrated to another CPU.  Currently, this only checks to see if
   we're an interrupt handler.  Eventually this will also be used to support
   CPU binding.

MFP4:
	o define EP_W2_ALT_EEPROM.  we don't use it yet, but may soon.
MFp4:
o Minor tweak to error processing in ep_alloc.
MFp4:
o Remove redundant $FreeBSD$
o Better comments about ep_get_macaddr.
o remove one tab in a switch statement (style only)
o Recognize ID 0x0035 as the device ID for the 3CXEM556 that I have.  This
  makes the 3CXEM556 work for me.  Not 100% sure this is the assigned ID,
  as I don't have the datasheets for this part, but it does work and get
  the correct ethrnet address.
o Comment about the whole fake IRQ 3 thing.  some need it, some don't, all
  work with it.
MFp4:
o Fix MFC cards.  We were bogusly setting CCR_IOBASE[01] and CCR_IOLIMIT.
  now when we activate the resource, we adjust these for MFC cards, per the
  spec.
o Change type of pf_mfc_* to be bus_addr_t, which is more correct than
  long.

This makes my 3C362D/3C363D and 3CXEM556 cards work!  Woo Hoo!
