While the BIOS support for INT10h emulation has been set up, any
modification of the display should wait until the kernel requests
video initialization with INBV/bootvid.
The latter will call HalResetDisplay() (that calls HalpBiosDisplayReset())
at the correct time.
This avoids an useless video mode change and reset when booting ReactOS.
- Don't use CONFIG_SMP, this isn't handled in (most of) hal
- Add a dummy HalpSetupProcessorsTable for UP
- Call HalpRegisterKdSupportFunctions only for processor 0

Introduce the initial changes needed to get other processors up and into kernel mode.
This only supports x86 as of now but is the first real step towards using other system processors.
This will be needed for compatibility with x86 Windows Vista/7 videoprt.sys builds.
Might be also useful in future for platforms (x86 , ...) where V86 mode is not available or buggy.

This allows to somewhat reduce their size, and the resulting size
of the generated hal.dll file.

Only done in our own code, not in 3rd-party or in PSDK headers
(official ones also have such typos in defines...)
(NOTE: apparent "Uknown" typo in dll/cpl/sysdm/smbios.c is on-purpose:
typo by the manufacturer.)
- Remove ContextValue variable. This variable erroneously truncated
*Context value (that can contain a pointer value) to 32 bits.
- Gracefully fail instead of asserting.

Use an INT call stub and exit on the address after the stub instead or using iret (some BIOS code uses int / iret internally). This fixes the messed up display when trying to switch modes.
Reference: https://wiki.osdev.org/PCI#Address_and_size_of_the_BAR
To determine the amount of address space needed by a PCI device,
you must save the original value of the BAR, write a value
of all 1's to the register, then read it back.
Note: 64-bit BARs are not supported yet.
Fixes compilation because the Hal(Private)DispatchTable's, defined in
the bootloader's NTOS stub, are not external imports, as they would be
for a standard HAL.
This also removes the following warnings, that were present because,
as the ACPICA acpi.h header was used as PCH (instead of none, or the
hal's own main header), it was "included" before any other header
-- and in particular, before hal.h -- and as a result, colliding defines
were still defined even if the #undef tricks were used for them.
