OVMF is built from edk2 sources so that's where its version number comes
from (logically). The edk2 version number is 2014-12-10, so this change
only ensures the version numbers won't drift apart in the future. (There
is no hash change.)
This reverts commit 3a4e2376e4.
The reverted commit caused the fix for CVE-2016-9602 not to be applied
for qemu_test because it conflicts with the force-uid0-on-9p.patch.
So with the rebase of the patch on top of the changes of the
CVE-2016-9602.patch, both patches no longer conflict with each other.
I've tested this with the "misc" NixOS test and it succeeds.

* CVE-2017-5857
* CVE-2017-5987
* CVE-2017-6058
Also:
* provides a bunch of build options
* documents build options config in longDescription
* provides a bunch of predefined packages and documents them some more
* sources' hashes stay the same
Fixes:
* CVE-2017-2615
* CVE-2017-5667
* CVE-2017-5898
* CVE-2017-5931
* CVE-2017-5973
We are vulnerable to even more CVEs but those are either not severe like
memory leaks in obscure situations or upstream hasn't acknowledged the
patch yet.

XSA-197 Issue Description:
> The compiler can emit optimizations in qemu which can lead to double
> fetch vulnerabilities. Specifically data on the rings shared
> between qemu and the hypervisor (which the guest under control can
> obtain mappings of) can be fetched twice (during which time the
> guest can alter the contents) possibly leading to arbitrary code
> execution in qemu.

XSA-199 Issue Description:
> The code in qemu which implements ioport read/write looks up the
> specified ioport address in a dispatch table. The argument to the
> dispatch function is a uint32_t, and is used without a range check,
> even though the table has entries for only 2^16 ioports.
>
> When qemu is used as a standalone emulator, ioport accesses are
> generated only from cpu instructions emulated by qemu, and are
> therefore necessarily 16-bit, so there is no vulnerability.
>
> When qemu is used as a device model within Xen, io requests are
> generated by the hypervisor and read by qemu from a shared ring. The
> entries in this ring use a common structure, including a 64-bit
> address field, for various accesses, including ioport addresses.
>
> Xen will write only 16-bit address ioport accesses. However,
> depending on the Xen and qemu version, the ring may be writeable by
> the guest. If so, the guest can generate out-of-range ioport
> accesses, resulting in wild pointer accesses within qemu.

XSA-207 Issue Description:
> Certain internal state is set up, during domain construction, in
> preparation for possible pass-through device assignment. On ARM and
> AMD V-i hardware this setup includes memory allocation. On guest
> teardown, cleanup was erroneously only performed when the guest
> actually had a pass-through device assigned.

XSA-209 Issue Description:
> When doing bitblt copy backwards, qemu should negate the blit width.
> This avoids an oob access before the start of video memory.

Putting information in external JSON files is IMHO not an improvement
over the idiomatic style of Nix expressions. The use of JSON doesn't
add anything over Nix expressions (in fact it removes expressive
power). And scattering package info over lots of little files makes
packages less readable over having the info in one file.
`DOCKER_GITCOMMIT` needs to match the tagged commit used to build the
binary. The current commit refers to 1.12.1 and wasn't update each
time we updated the package. Using a variable near the version and
adding a comment so we don't forget to update next time.

- Update docker version to 1.13.0.
- Introduce now docker-proxy package (from libnetmork).
- Use overrideDerivation to set the correct version for docker.
- Update tini to make sure we can build it static.

This brings VirtualBox to the latest upstream version, which also fixes
building the modules against kernel 4.9.0.
Tested against all the the "virtualbox" subtests on x86_64-linux.
The "misc" NixOS test is using Nix to query the store and it tries to
change the ownership of it while doing so.
This fails if Nix is not in a seccomp-sandboxed userid namespace, so
let's make chown() a no-op when applied to store paths.
Fixes the misc test (and possibly future tests) on older Nix versions.
