[console] Allow usage to be defined independently for each console
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

[debug] Expose pause() and more() debugging functions
Include the pause() and more() debugging functions within the general
iPXE debugging framework, by introducing DBGxxx_PAUSE() and
DBGxxx_MORE() macros.

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resources has been revoked by the registrant of the domain.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

[i386] Change [u]int32_t to [unsigned] int, rather than [unsigned] long
This brings us in to line with Linux definitions, and also simplifies
adding x86_64 support since both platforms have 2-byte shorts, 4-byte
ints and 8-byte long longs.
Split debug functions out into core/debug.c, so that they can be
automatically linked in on demand.
Corrected warnings in misc.c. strtoul() really should be
unsigned long strtoul ( const char *p, const char **endp, int base )
but such is not the ANSI standard.
