Add FILE_LICENCE declarations to almost all files that make up the
various standard builds of gPXE.

ns8390.c can produce four different drivers (one PCI, three ISA.)  The
ISA driver requires setting a few macros; do that by setting defines
in stub files instead of using src/Config.

Currently, all the ISA drivers are broken (they were not enabled by
default), so #if 0 them out.

This needs to be done manually because if the irq() routine is
implemented then we want something like "nic->irqno = pci->irqno;",
else we do "nic->irqno = 0;" nic->ioaddr may also need to be set
carefully.

Also added local variables to end of many files, for emacs indentation
to match kernel style (tab does 8 space indent).

This driver really needs to be rewritten.
It tries to build both ISA and PCI images,
and makes life diffifult for the build system
and rom-o-matic.net.  The warning was just a reminder
that it needs to be cleaned up and re-factored
to split the PCI and ISA drivers.

ISA 3c509 is currently non-functional, although the EISA (3c509-eisa) and
MCA (3c529) variants should build OK.

None of this code is yet tested.

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).

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.
