9c8531c8a5 nixos/*: replace <replaceable>s with «thing»
we can't embed syntactic annotations of this kind in markdown code
blocks without yet another extension. replaceable is rare enough to make
this not much worth it, so we'll go with «thing» instead. the module
system already uses this format for its placeholder names in attrsOf
paths.

nixos/qemu-vm: allow custom partitions and filesystems in VM
Potential use cases for disabling `useDefaultFilesystems` include:

  - Testing with uncommon filesystem layouts
  - Testing scenarios where swapping occurs
  - Testing with LUKS-encrypted disks

6af3e61632 nixos/qemu-vm: allow booting VM with the custom kernel
While doing kernel development with the nixos testing infrastructure, it
is useful to quickly compile the kernel on the side and boot it in the testing VM.

This patch allows overriding the kernel through the environment
variable. For example, the following:

$ NIXPKGS_QEMU_KERNEL_testvm=$LINUX_SRC/arch/x86/boot/bzImage $VM/bin/nixos-test-driver

runs testvm testing VM with the fresh kernel compiled in $LINUX_SRC.

fc614c37c6 nixos/documentation: split options doc build
most modules can be evaluated for their documentation in a very
restricted environment that doesn't include all of nixpkgs. this
evaluation can then be cached and reused for subsequent builds, merging
only documentation that has changed into the cached set. since nixos
ships with a large number of modules of which only a few are used in any
given config this can save evaluation a huge percentage of nixos
options available in any given config.

in tests of this caching, despite having to copy most of nixos/, saves
about 80% of the time needed to build the system manual, or about two
second on the machine used for testing. build time for a full system
config shrank from 9.4s to 7.4s, while turning documentation off
entirely shortened the build to 7.1s.

4ec119009b virtualisation/qemu-vm: Double the default diskSize
The default has been unchanged for a decade. Space is cheaper and
software catches up with that. Let's not make our testing harder
than necessary by default.

nixos/qemu-vm: use qemu_kvm
qemu_kvm is only built for one architecture, so it's smaller and takes
MUCH less time to build if it has to be built from source.  And this
module doesn't support running a VM for one architecture from another
architecture, so the one architecture is all we'll need.

af9f6d9a2a nixos/qemu-vm: Rename pathsInNixDB to additionalPaths
pathsInNixDB isn't a very accurate name when a Nix store image is
built (virtualisation.useNixStoreImage); rename it to additionalPaths,
which should be general enough to cover both cases.

84839b395f nixos/qemu-vm: Allow building a Nix store image instead of using 9p
Add the `useNixStoreImage` option, allowing a disk image with the
necessary contents from the Nix store to be built using
make-disk-image.nix. The image will be mounted at `/nix/store` and
acts as a drop-in replacement for the usual 9p mounting of the host's
Nix store.

This removes the performance penalty of 9p, drastically improving
execution speed of applications which do lots of reads from the Nix
store. The caveats are increased disk space usage and image build
time.

nixos/qemu-vm: fix running VM with QEMU_NET_OPTS
I realized quite recently that running a test VM - as documented in the
manual - like

    QEMU_NET_OPTS='hostfwd=tcp::8080-:80'  ./result/bin/nixos-run-vms

doesn't work anymore on `master`. After bisecting I realized that the
introduction of a forward-port option[1] is the problem since it adds a
trailing comma even if no forwarding options are specified via
`virtualisation.forwardPorts`. In that case, the networking options
would look like `-netdev user,id=user.0,,hostfwd=tcp::8080-:80' which
confused QEMU and thus the VM refused to start.

Now, the trailing comma is only added if additional port forwards are
specified declaratively.

nixos/lib/qemu-flags: rename to qemu-common
The current name is misleading: it doesn't contain cli arguments,
but several constants and utility functions related to qemu.
This commit also removes the use of `with import ...` for clarity.

39fad297fd nixos: fix "nixos-rebuild build-vm-with-bootloader" for EFI systems
`nixos-rebuild build-vm-with-bootloader` currently fails with the

    fileSystems."/".device = "/dev/sda1";
    boot.loader.systemd-boot.enable = true;
    boot.loader.efi.canTouchEfiVariables = true;
  }
  EOF

Fix it by setting virtualisation.useEFIBoot = true in qemu-vm.nix, when
efi is needed.

And remove the now unneeded configuration in
./nixos/tests/systemd-boot.nix, since it's handled globally.

Before:
* release-20.03: successful build, unsuccessful run
* release-20.09 (and master): unsuccessful build

After:
* Successful build and run.
