c63a6d94f6 NOVA: add chain_loader 'bender'
'Bender' can detect serial ports accessible via PCI and writes the I/O ports
to the Bios Data area (BDA).

Usage together with the PXE bootloader ease life running Genode/NOVA on native
hardware, where a standard serial device isn't available anymore anywhere.

ae6257dce1 Use NOVA microkernel from github, add 64bit
Use git to get recent kernels from github. Adjust NOVA patch to compile
with recent github version. Patch and use makefile of NOVA microkernel
to avoid duplicated (and outdated) makefile in Genode

Furthermore, this patch adds support for using NOVA on x86_64. The
generic part of the syscall bindings has been moved to
'base-nova/include/nova/syscall-generic.h'. The 32/64-bit specific
parts are located at 'base-nova/include/32bit/nova/syscalls.h' and
'base-nova/include/64bit/nova/syscalls.h' respectively.

On x86_64, the run environment boots qemu using the Pulsar boot loader
because GRUB legacy does not support booting 64bit ELF executables.

In addition to the NOVA-specific changes in base-nova, this patch
rectifies compile-time warnings or build errors in the 'ports' and
'libports' repositories that are related to NOVA x86_64 (i.e., Vancouver
builds for 32bit only and needed an adaptation to NOVAs changed
bindings)

Fixes #233, fixes #234

97b978c6c8 Fix sector calculation in GRUB's stage2_eltorito
The sector number was not calculated correctly for sector sizes < 2048
bytes. This commit updates the stage2_eltorito binary file, which was
created from CVS GRUB legacy (tag 'release_0_97') after applying Adam
Lackorzynski's 'os.8' patch
(http://os.inf.tu-dresden.de/~adam/grub/0.97/grub-0.97-os.8.diff.gz)
and the following patch:
