Default to \n -> \r\n conversion in the ANSI and xserial modules,
rather than relying on escape codes to make that behave.  This
effectively means that as far as the serial port is concerned, this
behavior cannot be turned off (with less than having the xserial state
machine interpret this sequence) and the escape code *should not* be
used.

That is fine for our applications, though.

Make sure we don't trash a useful value in errno.

In include/sys/pci.h we have

#define MAX_PCI_BUSES 255

and

struct pci_bus_list {
        struct pci_bus pci_bus[MAX_PCI_BUSES];
        uint8_t count;
};

And in lib/pci/scan.c

for (bus = 0; bus <= MAX_PCI_BUSES; bus++) {

    pci_bus_list->pci_bus[bus].pci_device_count = 0;

Fix possible overflows and introduce MAX_PCI_FUNC.

Aligning versions of memcpy/memmove/mempcpy/memset for libcom32.

Begin the process of centralizing configurables.

Improve "make install" and "make netinstall"; add "make
extbootinstall".

Move source files out of the root directory; the root is a mess and
has become virtually unmaintainable.  The Syslinux core now lives in
core/; the Linux and generic utilities has moved into utils/, and
copybs.com has moved into dos/; it had to go somewhere, and it seemed
as good a place as any.
