Be bit more robust.
* Don't use addresses and sizes larger than
32 bit address boundaries.
* Don't take modules of size 0, at address 0 and if aux is 0.

Fixes#269
Allocate exc_pt_sel inside Thread_base object
instead of pager object, since it is a thread
specific characteristic.
Same for freeing of the thread capabilities:
- ec, sc, rs, exc_pt_sel is thread specific
and has nothing to do in server nor pager object.
Don't allocate ec cap twice, in pager.cc and thread_start.cc.
Unmap of utcb has to be done in destructor of thread class, not
in pager class. Free capability selectors of ec and rs.
Invoke cancel_blocking before calling the
cleanup portal of the rpc_entrypoint. If a rpc_entrypoint
is blocked in a semaphore the cleanup call gets
stuck forever.
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to avoid duplicated (and outdated) makefile in Genode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
With this patch clients of the RM service can state if they want a mapping
to be executable or not. This allows dataspaces to be mapped as
non-executable on Linux by default and as executable only if needed.
Partially fixes#176.
This patch unifies the Native_capability classes for the different kernel
platforms by introducing an appropriate template, and eliminating naming
differences. Please refer issue #145.
