fc6bcd9f9f NOVA: update to latest kernel revision
The Demo of 64bit Genode/NOVA fails during the booting phase when
physical memory was tried to be mapped lying above 4G boundary.
(qemu -m 4096 triggered it on some systems). The memory never got
mapped and the attempt to access the virtual region resulted
in a unexpected page fault inside Genode core.

The latest revision removed the artificial boundary of 4G for 64bit.

Example trace showing the issue:
([-1] lines show debugging output that mapping failed)

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to avoid duplicated (and outdated) makefile in Genode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
