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).

Provide a mechanism for consoles to update the recorded console width
and height, and use this width and height to provide the curses COLS
and LINES variables.

We choose not to use ANSI escape sequences to obtain the width and
height, for two reasons:

- iPXE's model is that all output is sent to all consoles; we could
  therefore end up with multiple consoles reporting conflicting widths
  and heights

- when a serial console is in use, we probably don't want to resize
  the output shown on the BIOS console to match the size of the serial
  console, since it's likely that the serial console is in use only
  for debugging.

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resources has been revoked by the registrant of the domain.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

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

curses.h so that you don't have to suffer the curses namespace pollution
just to get the symbolic key names.

abstraction.

- changes made to some constants and macros
- changes made to _curses_screen struct
- identified and removed prototypes for yet more unsupportable functions

- implemented hline/vline (part of wborder family)
- screen cursor now relocates at same time as window cursor when
  restoring after a non-wrapping function

- fixes to wborder (same)
- addition of a few minor functions

- added extern declarations for global vars
- removed comments from static inlines (too time consuming to do them
  all, considering all so far have been due to the ridiculous amount of
  redundancy within the API spec)
- removed a few more extern func decls for funcs that cannot be
  implemented at this time
