The Nixos Qemu VM that are used for VM tests can now start without
boot menu even when using a bootloader.
The Nixos Qemu VM with bootloader can emulate a EFI boot now.
Because we have to rely on setuid wrappers on NixOS, we can't easily
hardcode the executable paths and set it 4755. So for all calls, we need
to change the runtime path executable directory to /var/setuid-wrappers/
and for verification we need to retain the executable directory.
Also note, that usually VBoxNetAdpCtl, VBoxNetDHCP, VBoxNetNAT, VBoxSDL
and VBoxVolInfo don't reside in directories that are commonly in PATH,
but in /usr/lib/virtualbox in most mainstream distros. But because the
names of these executables are distinctive enough to not cause
collisions with other setuid programs, I'll leave it like that and not
patch up setuid-wrappers.

Not really changes anything in functionality, but makes it easier to
change the build type to "debug", for example.

Just accidentally found this while debugging and it's needed for
fetching a few interface details, not sure however whether because of
this anything has been broken so far.

Instead of coping it to $out and later deleting it, we now exclude the
src directory during copy. Also, we no longer cd into the release
directory during installPhase, which should make sure that we are
constantly in $sourceRoot.

Fixes this error, as seen when trying to open a guest VM when
virt-viewer is accessed over ssh with X forwarding:
GLib-GIO-ERROR **: Settings schema 'org.gnome.system.proxy' is not installed
A similar issue was fixed for virt-manager in commit
fb8a2b3be7 ("virt-manager: fix missing
schema error")
We divert to the $out/share/virtualbox directory only if we have
hardening enabled, so let's put the extension pack into
$out/libexec/virtualbox instead if we're compiling without hardening.

* Add missing dependency on 'spice_protocol'
* Fix new build error which came now that ./configure enables SPICE support:
building virt-viewer
CCLD virt-viewer
/nix/store/b8qhjrwf8sf9ggkjxqqav7f1m6w83bh0-binutils-2.23.1/bin/ld: cannot find -lgdbm

collect2: error: ld returned 1 exit status
Fix by adding gddbm and libcap as inputs. Yes, libcap is needed
_in addition_ to libcap_ng (I tested removing libcap_ng, it failed).
Without this change, virt-viewer cannot be used with guests machines
that uses SPICE.
Yes, this is only on the package level, so it's possible to use
VirtualBox for example installed by nix-env -i, which of course doesn't
have access to the functionality provided by the various VirtualBox
kernel modules.

With hardening, we need to go a bit further rather than just allowing
/nix/store being world-writable. We now use fakeroot to make sure the
VBoxExtPackHelperApp won't moan that the files are not owned by root.
They are, but only outside of the chrooted build process.
Another issue with using fakeroot is that it doesn't seem to cope well
with arguments that contain spaces. That's why I've piped the call into
${stdenv.shell}.
Now, the really gory and confusing part is the introduction of
VBOX_PATH_APP_PRIVATE_ARCH_TOP and the change of VBOX_PATH_APP_PRIVATE.
The VBOX_PATH_APP_PRIVATE_ARCH is *only* for modules and is checked by
the hardened implementation against whether things like VMMR0.r0 or
VBoxVMM.so reside in that directory. As a side note: I admit that the
whole libexec directory is quite polluted with stuff that shouldn't be
there, but for now we've broken enough things and will tear apart the
whole structure at some day in the future[TM].
For the confusing part we have VBOX_PATH_APP_PRIVATE_ARCH_TOP, which
_should_ be the same as VBOX_PATH_APP_PRIVATE_ARCH but unfortunately,
the hardened implementation is checking against this directory (in
IsValidBaseDir) for the extension pack(why!?).
Of course, we could put even that into the libexec directory, somewhat
similar as the official package, but after all, let's at least *try* to
separate things.

We are already checking whether /nix/store has the sticky bit set, so if
it is world-writable as well it doesn't mean that the actual store path
is writable. Let alone the fact that it is only writable during the
build process.
This should fix installing the extension pack when enableExtensionPack
is used.

VirtualBox with hardening support requires the main binaries to be
setuid root. Using VBOX_WITH_RUNPATH, we ensure that the RPATHs are
pointing to the libexec directory and we also need to unset
VBOX_WITH_ORIGIN to make sure that the build system is actually setting
those RPATHs.
The hardened.patch implements two things:
* Set the binary directory to the setuid-wrappers dir so that
VboxSVC calls them instead of the binaries from the store path. The
reason behind this is because nothing in the Nix store can have the
setuid flag.
* Excempt /nix/store from the group permission check, because while it
is group-writeable indeed it also has the sticky bit set (and also
the whole store is mounted read-only on most NixOS systems), so we're
checking on that as well.
Right now, the hardened.patch uses /nix/store and /var/setuid-wrappers
directly, so someone would ever want to change those on a NixOS system,
please provide a patch to set those paths on build time. However, for
simplicity, it's best to do it when we _really_ need it.

Traversing the full source tree is unneccessary, because the calls are
only done within make files. Hence we only substitute make files now.

Now, Bochs expression has a bunch of configurable options!
Unhappily, it is a big and complex project, and some configure options
are in constant clash. But the set created for now is very usable and
stable.
