[libc] Print "<NULL>" for wide-character NULL strings
The existing code intends to print NULL strings as "<NULL>" (for the
sake of debug messages), but the logic is incorrect when handling
wide-character strings. Fix the logic and add applicable unit tests.

[legal] Relicense files under GPL2_OR_LATER_OR_UBDL
These files cannot be automatically relicensed by util/relicense.pl
since they either contain unusual but trivial contributions (such as
the addition of __nonnull function attributes), or contain lines
dating back to the initial git revision (and so require manual
knowledge of the code's origin).

[console] Fix display of characters with top bit set
Inhibit implicit sign-padding of characters with the top bit set
(e.g. accented characters), which confuses the mucurses library by
colliding with the bits used to store character attributes and
colours.

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resources has been revoked by the registrant of the domain.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.

Shaved around 100 bytes off vsprintf.o. It's now 50 bytes smaller than
the old implementation and provides much more conformant semantics,
including the ability to return the number of characters that would have
been printed to the string had the buffer been big enough. (iSCSI needs
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.
Added errno, strerror and the "%m" printf metacharacter. These will allow
us to return proper PXE status codes, while simultaneously allowing for
more consistent error reporting (complete with verbose error messages as a
build-time option).
