Add PXE driver-scanning code, capable of locating all PXE ROMs in a system
...
and matching them up to (e.g. PCI) devices.

Obsolete; net driver functionality is now in undi_net.c and bus driver

functionality is now in pxebus.c. (Not all bus functionality is ported
across yet.)

Added PXE bus driver (with support only for using PXE structures found
...
lying about in memory, not for loading from ROM), and UNDI net driver.

Add as a separate file so that we can do "make bin/xxxx.kpxe" rather than

having to edit PXELOADER_KEEP_ALL as a config option.

Some BIOSes return 0xe0 for extended characters. Just assume that

anything over 0x80 is an extended character.

Prevent NULL from ever pointing to some real code or data. (This was
...
causing the serial console to ignore input, because it happened to end up
linked with serial_ischar() at address 0, which core/console.c decided was
invalid).

Optimise bios_putchar for speed(!) by avoiding two separate real-mode

werase() inside bochs or qemu.

Avoid draining the keyboard buffer during gateA20_set(). It shouldn't
...
technically be necessary, because the "enable A20" command requires
only that the keyboard controller is ready to accept input (i.e. that
its input buffer is empty), and shouldn't also require that the
keyboard is ready to send output (i.e. that its output buffer is also
empty). See http://www.smsc.com/main/tools/io-bios/42i.pdf section
3.1 ("Command Invocation") for a justification.
gateA20_set() is called on every real-mode transition (in case some
idiot piece of external code such as Intel's PXE stack decided it
would be fun to re-disable A20), so draining the keyboard buffer means
that we end up losing keypresses on some systems. In particular, this
makes typing at the command line almost impossible, and causes
Etherboot to ignore Ctrl-Alt-Del.
We should really implement a gateA20_test() function to verify that
gate A20 has been correctly enabled, and think about adding other
commonly-used methods such as Fast Gate A20.

We don't actually have a stdio.h header file. Our printf() functions are
...
defined in vsprintf.h. (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)
There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.

Check to see if we've reached the end of the map before attempting to

skip past an empty region, otherwise we end up generating an infinitely
long e820 map. (Yes, there *are* real systems that provide e820 maps
with a zero-length region at the end...)

actually do anything with the result, since it carried on using us

Updated PXE UDP implementation to use the new Etherboot UDP API.
...
Updated PXE API dispatcher to use copy_{to,from}_user, and moved to
arch/i386 since the implementation is quite architecture-dependent.
(The individual PXE API calls can be largely
architecture-independent.)

Fix bug with >256 cylinders.
...
Allow our functions to return a non-zero, non-error status (since the
INT 13 Extensions Check has to return the API version in the register
that is otherwise always used for the error code).
Report a non-zero API version from the INT 13 Extensions Check; GRUB
now uses extended reads.

Cut out almost all the optional code paths, drastically simplifying the

flow of control through this code.
We now always add PCI and PnP headers even for ISA ROMs; there's no harm
in doing so.
UNDI loader is still missing.
