Kill off the static single net device and move to proper dynamic
registration (which we need with the new device model).

Break the (flawed) assumption that all network-layer protocols can use
ARP; such network-layer protocols (i.e. IPv4) must now register as an ARP
protocol using ARP_NET_PROTOCOL() and provide a single method for checking
the existence of a local network-layer address.

not-yet-updated drivers to at least function.

point trying to use the old boot sequence.  Replaced with a call to the
AoE demo code, so that people can at least build and try something useful.

This is the core portion of the async I/O interface.

need for a CONFIG_RELOCATE.

- implemented hline/vline (part of wborder family)
- screen cursor now relocates at same time as window cursor when
  restoring after a non-wrapping function

Also trim another eight bytes from vsprintf.o.  :)

- fixes to wborder (same)
- addition of a few minor functions

- implemented color_content, wborder, wblrtobot, wclrtoeol, wcolor_set and several small functions
- added rest of expected global variables

Corrected warnings in misc.c.  strtoul() really should be
  unsigned long strtoul ( const char *p, const char **endp, int base )
but such is not the ANSI standard.

Generic PCI code now handles 64-bit BARs correctly when setting
"membase"; drivers should need to call pci_bar_start() only if they want
to use BARs other than the first memory or I/O BAR.

Split rarely-used PCI functions out into pciextra.c.

Core PCI code is now 662 bytes (down from 1308 bytes in Etherboot 5.4).
284 bytes of this saving comes from the pci/pciextra split.

Cosmetic changes to lots of drivers (e.g. vendor_id->vendor in order to
match the names used in Linux).

for use by malloc().

This breaks the image-loading code (which previously used the heap to
allocate the buffer for downloading the image), but that's not a major
concern since I'm going to tear out all the image formats within the next
couple of days anyway.  Byebye, NBI!  :)

Shaved around 100 bytes off vsprintf.o.  It's now 50 bytes smaller than
the old implementation and provides much more conformant semantics,
including the ability to return the number of characters that would have
been printed to the string had the buffer been big enough.  (iSCSI needs
this functionality).

stack, even if we don't yet print it out.

At some point, vsprintf() needs to be fixed up so that it can correctly
cope with limited-sized buffers (i.e. vsnprintf), long longs, and
standard format specifiers (e.g. "%04x").  We should also remove the
special types (MAC addresses and IP addresses).  This would then enable
us to use gcc's ability to type-check printf format strings.

portions such as the stack) during the installation process.

init_fns() are called from main().  We need to think about initial
control flow some more.

compile, even if it won't yet be safe.

Yes, you really can do it in 65 bytes.

alignment and size are both powers of two, and there's no way to
specify an alignment through the malloc() interface anyway.

aligned blocks.

Moved header to include/malloc.h, since we now also provide the
POSIX-like malloc()/free() pair.

Not yet tested.

even when __atribute__ (( unused )) is correctly set...

I want to get to the point where any header in include/ reflects a
standard user-level header (e.g. a POSIX header), while everything that's
specific to gPXE lives in include/gpxe/.  Headers that reflect a Linux
header (e.g. if_ether.h) should also be in include/gpxe/, with the same
name as the Linux header and, preferably, the same names used for the
definitions.

kernel.

Removed obsolete struct arprequest from if_arp.h and put it in nic.c so
that nic.c will still compile.  ARP will very shortly be handled by
net/arp.c instead.

size.  (The restriction on the size of free blocks remains.)
