Add the concept of a "console usage", such as "standard output" or
"debug messages". Allow usages to be associated with each console
independently. For example, to send debugging output via the serial
port, while preventing it from appearing on the local console:
#define CONSOLE_SERIAL CONSOLE_USAGE_ALL
#define CONSOLE_PCBIOS ( CONSOLE_USAGE_ALL & ~CONSOLE_USAGE_DEBUG )
If no usages are explicitly specified, then a default set of usages
will be applied. For example:
#define CONSOLE_SERIAL
will have the same affect as
#define CONSOLE_SERIAL CONSOLE_USAGE_ALL

There is no INT 10 call for "display character with attribute,
advancing the cursor and scrolling the screen as necessary". We
therefore make two INT 10 calls: INT 10,09 to write the character with
its attribute at the current cursor position, and then INT 10,0e to
(re)write the character (leaving the attribute unchanged), advance the
cursor position and scroll as necessary.
This confuses the serial-over-LAN console redirection feature provided
by some BIOSes.
Fix by performing the INT10,09 only when necessary to change the
existing attribute.

INT 16,01 will discard some extended keystrokes on some BIOSes, making
it impossible for iPXE to detect keypresses such as F12. Fix by using
INT 16,11 instead.

The function keys F5-F12 all conform to the same ANSI pattern as the
other "special" keys that we currently recognise. Add these key
definitions, and shrink the representation of the ANSI sequences in
bios_console.c to compensate.

Access to the gpxe.org and etherboot.org domains and associated
resources has been revoked by the registrant of the domain. Work
around this problem by renaming project from gPXE to iPXE, and
updating URLs to match.
Also update README, LOG and COPYRIGHTS to remove obsolete information.
