- made some of the bit shifting attribute access simpler (in my mind)
...
- added extern declarations for global vars
- removed comments from static inlines (too time consuming to do them

Add the concept of a "user pointer" (similar to the void __user * in
...
the kernel), which encapsulates the information needed to refer to an
external buffer. Under normal operation, this can just be a void *
equivalent, but under -DKEEP_IT_REAL it would be a segoff_t equivalent.
Use this concept to avoid the need for bounce buffers in int13.c,
which reduces memory usage and opens up the possibility of using
multi-sector reads.
Extend the block-device API and the SCSI block device implementation
to support multi-sector reads.
Update iscsi.c to use user buffers.
Move the obsolete portions of realmode.h to old_realmode.h.
MS-DOS now boots an order of magnitude faster over iSCSI (~10 seconds

Strip down i386 PCI configuration space I/O to the bare minimum. A
...
typical build will now include 880 bytes of PCI support code, compared to
2327 bytes in Etherboot 5.4.
(There is a slight cost of around 5 extra bytes per access to a
non-constant config space address; this should be an overall win.
Driver-specific accesses will usually be to constant addresses, for
which there is no additional cost.)

Restructured PCI subsystem to fit the new device model.
...
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).

Shaved around 100 bytes off vsprintf.o. It's now 50 bytes smaller than

this functionality).

At least cope with "%llx" by reading the correct-sized va_arg from the

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.

Preserve the whole of %esp across prot_call(). We have to split this

between the low half stored in the static variable rm_sp, and the high
half stored on the prot_call() stack, because:
Just using the stack would screw up when a prot_call()ed routine
executes a real_call(); it would have no way to find the current top of
the RM stack.
Extending rm_sp to rm_esp would not be safe, because the guarantee that
rm_sp must return to the correct value by the time an external
real-mode call returns applies only to %sp, not to %esp.

Doing so, in fact, seems to expose an assembler bug; (a-b-0) is

Header rearrangement.
...
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.

Added prototype for inet_ntoa, even though we don't have the function

Add include/gpxe as a directory to scan.

Exclude proto/uip, since uip.c and uip_arp.c both have global variables

Skeleton version: contains device driver (connecting to network via
