OVMF: separate output for ovmf binaries
OVMF{,CODE,VARS}.fd are now available in a dedicated fd output, greatly
reducing the closure in the common case where only those files are used (a
few MBs versus several hundred MBs for the full OVMF).

Note: it's unclear why `dontPatchELF` is now necessary for the build to
pass (on my end, at any rate) but it doesn't make much sense to run this
fixup anyway,

Note: my reading of xen's INSTALL suggests that --with-system-ovmf should
point directly to the OVMF binary.  As such, the previous invocation was
incorrect (it pointed to the root of the OVMF tree).  In any case, I have
only built xen with `--with-system-ovmf`, I have not tested it.

qemu module: add virtualisation.cores option
QEMU can allow guests to access more than one host core at a time.
Previously, this had to be done via ad-hoc arguments:

    virtualisation.qemu.options = ["-smp 12"];

Now you can simply specify:

    virtualisation.cores = 12;

Use overlayfs instead of unionfs-fuse in the VM tests
Overlayfs is quite a bit faster, e.g. with it the KDE 5 test takes ~7m
instead of ~30m on my laptop (which is still not great, since plain
9pfs is ~4m30s).

Enable virtualisation.writableStore by default
This works around:

  machine: must succeed: nix-store -qR /run/current-system | grep nixos-
  machine# error: changing ownership of path ‘/nix/store’: Invalid argument

Probably Nix shouldn't be anal about the ownership of the store unless
it's trying to build/write to the store.

Jörg Thalheim 1590461887 ntp: make timesyncd the new default
- most nixos user only require time synchronisation,
  while ntpd implements a battery-included ntp server (1,215 LOCs of C-Code vs 64,302)
- timesyncd support ntp server per interface (if configured through dhcp for instance)
- timesyncd is already included in the systemd package, switching to it would
  save a little disk space (1,5M)

nixos/tests: Use a patched QEMU for testing
The reason to patch QEMU is that with latest Nix, tests like "printing"
or "misc" fail because they expect the store paths to be owned by uid 0
and gid 0.

Starting with NixOS/nix@5e51ffb1c2, Nix
builds inside of a new user namespace. Unfortunately this also means
that bind-mounted store paths that are part of the derivation's inputs
are no longer owned by uid 0 and gid 0 but by uid 65534 and gid 65534.

This in turn causes things like sudo or cups to fail with errors about
insecure file permissions.

So in order to avoid that, let's make sure the VM always gets files
owned by uid 0 and gid 0 and does a no-op when doing a chmod on a store
path.

In addition, this adds a virtualisation.qemu.program option so that we
can make sure that we only use the patched version if we're *really*
running NixOS VM tests (that is, whenever we have imported
test-instrumentation.nix).

Tested against the "misc" and "printing" tests.

Eelco Dolstra 845c9b50bf boot.initrd.luks.devices: Change into an attribute set
This allows setting options for the same LUKS device in different
modules. For example, the auto-generated hardware-configuration.nix
can contain

  boot.initrd.luks.devices.crypted.device = "/dev/disk/...";

while configuration.nix can add

  boot.initrd.luks.devices.crypted.allowDiscards = true;

Also updated the examples/docs to use /disk/disk/by-uuid instead of
/dev/sda, since we shouldn't promote the use of the latter.

Allow usage of list of strings instead of a comma-separated string
for filesystem options. Deprecate the comma-separated string style
with a warning message; convert this to a hard error after 16.09.
15.09 was just released, so this provides a deprecation period during
the 16.03 release.

nixos/qemu-vm: Disable cache for $NIX_DISK_IMAGE
As @domenkozar noted in #10828, cache=writeback seems to do more harm
than good:

https://github.com/NixOS/nixpkgs/issues/10828#issuecomment-164426821

He has tested it using the openstack NixOS tests and found that
cache=none significantly improves startup performance.

nixos/vm-tests: Remove msize mount option
This seems to be the root cause of the random page allocation failures
and @wizeman did a very good job on not only finding the root problem
but also giving a detailed explanation of it in #10828.

Here is an excerpt:

  The problem here is that the kernel is trying to allocate a contiguous
  section of 2^7=128 pages, which is 512 KB. This is way too much:
  kernel pages tend to get fragmented over time and kernel developers
  often go to great lengths to try allocating at most only 1 contiguous
  page at a time whenever they can.

  From the error message, it looks like the culprit is unionfs, but this
  is misleading: unionfs is the name of the userspace process that was
  running when the system ran out of memory, but it wasn't unionfs who
  was allocating the memory: it was the kernel; specifically it was the
  v9fs_dir_readdir_dotl() function, which is the code for handling the
  readdir() function in the 9p filesystem (the filesystem that is used
  to share a directory structure between a qemu host and its VM).

  If you look at the code, here's what it's doing at the moment it tries
  to allocate memory:

    buflen = fid->clnt->msize - P9_IOHDRSZ;

    rdir = v9fs_alloc_rdir_buf(file, buflen);

  If you look into v9fs_alloc_rdir_buf(), you will see that it will try
  to allocate a contiguous buffer of memory (using kzalloc(), which is a
  wrapper around kmalloc()) of size buflen + 8 bytes or so.

  So in reality, this code actually allocates a buffer of size
  proportional to fid->clnt->msize. What is this msize? If you follow
  the definition of the structures, you will see that it's the
  negotiated buffer transfer size between 9p client and 9p server. On
  the client side, it can be controlled with the msize mount option.

  What this all means is that, the reason for running out of memory is
  that the code (which we can't easily change) tries to allocate a
  contiguous buffer of size more or less equal to "negotiated 9p
  protocol buffer size", which seems to be way too big (in our NixOS
  tests, at least).

After that initial finding, @lethalman tested the gnome3 gdm test
without setting the msize parameter at all and it seems to have resolved
the problem.

The reason why I'm committing this without testing against all of the
NixOS VM test is basically that I think we can only go better but not
worse than the current state.

We already have separate tests for checking whether the ISO boots

tests/installer.nix just tests nixos-install, from a regular NixOS VM
that uses the host's Nix store. This makes running the tests more
convenient because we don't have to build a new ISO after every
change.

confusing overloading.
