Validate INT 15h and 16h vectors more strictly. Traditionally these entry
points are fixed addresses and (U)EFI CSM specification also mandated that.
Unfortunately, (U)EFI CSM specification does not specifically mention this
is to call service routine via interrupt vector table or to jump directly
to the entry point. As a result, some CSM seems to install two routines
and acts differently, depending on how it was executed, unfortunately.
When INT 15h is used, it calls a function pointer (which is probably a UEFI
service function). When it jumps directly to the entry point, it executes
a simple and traditional INT 15h service routine. Therefore, actually there
are two possible fixes, i. e., this fix or jumping directly to the fixed
entry point. However, we chose this fix because a) keyboard typematic
support via BIOS is becoming extremely rarer and b) we cannot support random
service routine installed by a firmware or a boot loader. This should fix
Lenovo X220 laptop, specifically.

Add a new knob to atkbd(4) to enable typematic rate detection on boot,
which is now disabled by default. The detection is known to cause hangs
on boot with some new Lenovo laptops on FreeBSD/amd64.

MFC x86emu/x86bios emulator and make previously i386 only dpms and vesa
framebuffer driver, etc. work on FreeBSD/amd64.

A significant amount of improvements were done by jkim@ during the recent
months to make vesa(4) work better, over the initial code import. This
work is based on OpenBSD's x86emu implementation and contributed by
paradox <ddkprog yahoo com> and swell.k at gmail com.

Hopefully I have stolen all their work to 8-STABLE :)

All bugs in this commit are mine, as usual.

Rewrite x86bios and update its dependent drivers.

- Do not map entire real mode memory (1MB). Instead, we map IVT/BDA and
ROM area separately. Most notably, ROM area is mapped as device memory
(uncacheable) as it should be. User memory is dynamically allocated and
free'ed with contigmalloc(9) and contigfree(9). Remove now redundant and
potentially dangerous x86bios_alloc.c. If this emulator ever grows to
support non-PC hardware, we may implement it with rman(9) later.
- Move all host-specific initializations from x86emu_util.c to x86bios.c and
remove now unnecessary x86emu_util.c. Currently, non-PC hardware is not
supported. We may use bus_space(9) later when the KPI is fixed.
- Replace all bzero() calls for emulated registers with more obviously named
x86bios_init_regs(). This function also initializes DS and SS properly.
- Add x86bios_get_intr(). This function checks if the interrupt vector is
available for the platform. It is not necessary for PC-compatible hardware
but it may be needed later. ;-)
- Do not try turning off monitor if DPMS does not support the state.
- Allocate stable memory for VESA OEM strings instead of just holding
pointers to them. They may or may not be accessible always. Fix a memory
leak of video mode table while I am here.
- Add (experimental) BIOS POST call for vesa(4). This function calls VGA
BIOS POST code from the current VGA option ROM. Some video controllers
cannot save and restore the state properly even if it is claimed to be
supported. Usually the symptom is blank display after resuming from suspend
state. If the video mode does not match the previous mode after restoring,
we try BIOS POST and force the known good initial state. Some magic was
taken from NetBSD (and it was taken from vbetool, I believe.)
- Add a loader tunable for vgapci(4) to give a hint to dpms(4) and vesa(4)
to identify who owns the VESA BIOS. This is very useful for multi-display
adapter setup. By default, the POST video controller is automatically
probed and the tunable "hw.pci.default_vgapci_unit" is set to corresponding
vgapci unit number. You may override it from loader but it is very unlikely
to be necessary. Unfortunately only AGP/PCI/PCI-E controllers can be
matched because ISA controller does not have necessary device IDs.
- Fix a long standing bug in state save/restore function. The state buffer
pointer should be ES:BX, not ES:DI according to VBE 3.0. If it ever worked,
that's because BX was always zero. :-)
- Clean up register initializations more clearer per VBE 3.0.
- Fix a lot of style issues with vesa(4).

- Use x86bios_offset() instead of BIOS_PADDRTOVADDR() macro.[1]
- Clear all registers before calling real mode interrupt handlers as we did
for dpms and vesa and re-enable the function as it should be fixed by this.
- Tidy up register access. For example, when we call INT 0x15, AH=0xc0,
we used to initialize AX=0xc000 to clear AL at the same time but it is
very confusing. We don't have to do this any more because we are explicitly
clearing all registers now.
- Check size of system configuration table although it is almost always 8.
This is to make sure we are not reading some random low physical memory.
Hopefully it is just zero in that case. :-)
- Fix some style nits and add more comments.

Remove explicit calls to keyboard methods with their respective variants
implemented with macros. This patch improves code readability. Reasoning
behind kbdd_* is a "keyboard discipline".

List of macros is supposed to be complete--all methods of keyboard_switch
should have their respective macros from now on.

Functionally, this code should be no-op. My intention is to leave current
behaviour of code as is.
