AppleNetBoot.h is not taken from the EDK2 codebase and so cannot be
imported using include/ipxe/efi/import.pl. Mark as a native iPXE
header (by changing the include guard) to avoid breaking the import
process.

Mac OS X uses non-standard EFI protocols to obtain the DHCP packets
from the UEFI firmware.

We currently use the EFI_CPU_ARCH_PROTOCOL's GetTimerValue() method to
generate the currticks() timer, calibrated against a 1ms delay from
the boot services Stall() method.
This does not work on ARM platforms, where GetTimerValue() is an empty
stub which just returns EFI_UNSUPPORTED.
Fix by instead creating a periodic timer event, and using this event
to increment a current tick counter.

Add definitions of protocols observed to be used by wdsmgfw.efi, and
add a handle name type for ConIn, ConOut, and StdErr.

Entropy gathering via timer ticks is slow under UEFI (of the order of
20-30 seconds on some machines). Use the EFI_RNG_PROTOCOL if
available, to speed up the process of entropy gathering.
Note that some implementations (including EDK2) will fail if we
request fewer than 32 random bytes at a time, and that the RNG
protocol provides no guarantees about the amount of entropy provided
by a call to GetRNG(). We take the (hopefully pessimistic) view that
a 32-byte block returned by GetRNG() will contain at least the 1.3
bits of entropy claimed by min_entropy_per_sample().

The EFI_CONSOLE_CONTROL_PROTOCOL does not exist in the current UEFI
specification, but is required to enable text output on some older EFI
1.10 implementations (observed on an old iMac).
The header is not present in any of the standard include directories,
but can still be found in the EDK2 codebase as part of
EdkCompatibilityPkg.

The EFI FAT filesystem driver has a bug: if a block device contains no
FAT filesystem but does have an EFI_SIMPLE_FILE_SYSTEM_PROTOCOL
instance, the FAT driver will assume that it must have previously
installed the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL. This causes the FAT
driver to claim control of our device, and to refuse to stop driving
it, which prevents us from later uninstalling correctly.
Work around this bug by opening the disk I/O protocol ourselves,
thereby preventing the FAT driver from opening it.
Note that the alternative approach of opening the block I/O protocol
(and thereby in theory preventing DiskIo from attaching to the block
I/O protocol) causes an endless loop of calls to our DRIVER_STOP
method when starting the EFI shell. I have no idea why this is.

Expose iPXE's images as a UEFI file system, allowing the booted image
to access all images downloaded by iPXE.
This functionality is complementary to the custom iPXE download
protocol. The iPXE download protocol allows a booted image to utilise
iPXE to download arbitrary URIs, but requires the booted image to
specifically support the custom iPXE download protocol. The new
functionality limits the booted image to accessing only files that
were already downloaded by iPXE (e.g. as part of a script), but can
work with any generic UEFI image (e.g. the UEFI shell). Both
protocols are provided simultaneously, and are attached to the SNP
device handle.

Add a new network driver that consumes the EFI Simple Network
Protocol. Also add a bus driver that can find the Simple Network
Protocol that iPXE was loaded from; the resulting behavior is similar
to the "undionly" driver for BIOS systems.

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.
