The efi_pxe_mode struct which represents the PXE_BASE_CODE_PROTOCOL
Replace the placeholder paddings in the efi_pxe_mode struct with the
actual fields as defined in UEFI's PXE Base Code Protocol. Since
our efi_ip_address is a simple char array set a specific alignment
to the efi_ip_address fields, as expected by the UEFI spec.

Not complete, but enough for Shell.efi and SCT.efi. We'll implement the

Currently we set the function pointer for the CreateEventEx boot service

Shell.efi uses this, and supporting color attributes makes things look
nicer. Map the EFI fg/bg color attributes to ANSI escape sequences.
Not all colors have a perfect match, but spec just says "Devices
supporting a different number of text colors are required to emulate the
above colors to the best of the device’s capabilities".

Similar to a "real" UEFI implementation, the bootmgr looks at the
BootOrder and BootXXXX variables to try to find an EFI payload to load
and boot. This is added as a sub-command of bootefi.
The idea is that the distro bootcmd would first try loading a payload
via the bootmgr, and then if that fails (ie. first boot or corrupted
EFI variables) it would fallback to loading bootaa64.efi. (Which
would then load fallback.efi which would look for \EFI\*\boot.csv and
populate BootOrder and BootXXXX based on what it found.)

It needs to handle more device-path node types, and also multiple levels
of path hierarchy. To simplify this, initially construct utf8 string to
a temporary buffer, and then allocate the real utf16 buffer that is
returned. This should be mostly for debugging or at least not critical-
path so an extra copy won't hurt, and is saner than the alternative.
