Use libpci to access PCI config space. This *hopefully* will make it
less likely that some old machine hangs when failing to set the
requested video mode.

If we specify a smaller image than the screen size, tile it across the
screen rather than leaving a big black box. This may have to be made
configurable.
Also note that Syslinux currently does not handle the case of an image
bleeding off the end of the screen.

Make it possible to do a ymodem transfer even on the port used for a
serial console. Furthermore, on a serial console, get the parameters
from the serial console information, so port number and speed don't
have to be specified.

Instead of outputting data as it is generated, buffer it all in memory
and then output it all at once. This not only gives us exact size and
so on before we start, but turns out to be faster at least for TFTP.

Some partitioning program, including at least parted, apparently
create the list of logical partition headers nonlinearly with the
partition themselves. Thus, make it a requirement that then fit
inside the overall extended partition, but not inside the
corresponding sublogical partition.
