The mesa driver, which ends up in the installation image, needs to be known
before the installation is done (in other words: when running the qemu action,
it is to late as the image has already been generated). That's why one can
choose the Qemu mesa driver in `pmbootstrap init` now:
```
Device [qemu-amd64]:
Which mesa driver do you prefer for your Qemu device? Only select something other
than the default if you are having graphical problems (such as glitches).
Mesa driver (dri-swrast/dri-virtio) [dri-virtio]:
```
It is still possible to select `dri-swrast`, because `dri-virtio` may not work
in all cases, and that way we could easily debug it or experiment with other
mesa drivers (e.g. the "vmware" one, which is supported by mesa and Qemu).
Other changes:
* `pmbootstrap qemu` accepts a `--display` variable now, which passes the value
directly to `qemu`'s `display` option. It defaults to `sdl,gl=on` (@PureTryOut
reported that to work best with plasma mobile on his PC). `--display` and
`--spice` (which is still working) are mutually exclusive.
* Removed obsolete telnet port pass-through: We only use the debug telnet port
since osk-sdl has been merged.
* Add show-cursor to the Qemu command line, so it shows a cursor in X11
* Refactored the spice code (`command_spice` only returns the spice command,
because it has all necessary information already) and the spice port can be
specified on the commandline now (previously it was hardcoded in one place and
then always looked up from there).
* Start comments with capital letters.
* Keep the log on the screen a bit shorter (e.g. Qemu command is written to the
"pmbootstrap log" anyway, so there's no need to display it again).
* linux-postmarketos-stable: Adjust kernel configs
x86_64, armhf: enable as modules:
CONFIG_DRM_VIRTIO_GPU, CONFIG_VIRTIO_PCI, CONFIG_VIRTIO_BALLOON
aarch64: all 3 options were already enabled as built-in (no change)
* Set '-vga virtio' for mesa-dri-virtio
* XFCE4/Hildon: Log to syslog, see also:
<https://github.com/postmarketOS/pmbootstrap/pull/762>
* Fix XFCE4 didn't start in qemu-amd64, because it required
libEGL.so.1, which is provided by mesa-egl. This is a dependency
of device-qemu-amd64-x11 now. (It worked for Hildon and Weston,
because they pull mesa-egl in with other packages.)
@drebrez deserves much credit for this one for all the testing,
bisecting and for fixing everything. Thank you very much!

* devices which need a custom weston.ini ship it with a install_if
subpackage, so it only gets installed when weston is installed. This
sounds complicated, but is actually pretty clean in the APKBUILD.
* postmarketos-ui-weston: has a weston.ini.default, which enables
xwayland and uses fbdev as backend (because that's what most
devices use!). It defaults to the weston.ini.default if there is no
weston.ini (as installed by the device package).
* changed spaces to tabs for consistency, general minor refactoring of
device-APKBUILDs
* pmb.helpers.run: support running processes in background
* enable QXL driver support in the linux kernel configurations so
that we can also use SPICE to connect to the VM.
QXL is a paravirtual graphics driver with 2D support
The SPICE project aims to provide a complete open source solution for remote
access to virtual machines in a seamless way.
Both DRM_QXL and DRM_BOCHS are enabled as modules.
According to [1], on Linux guests, the qxl and bochs_drm kernel modules
must be loaded in order to gain a decent performance
* qemu: add new option --spice to connect to VM using a SPICE client
If specified, 'pmbootstrap qemu' will look for some SPICE client in the
user's PATH and run qemu using the QXL driver.
Currently supported spice clients are 'spicy' and 'remote-viewer' but
adding support for more clients can be easily done.
qemu with qxl support will run on port 8077/tcp, which doesn't belong to
any well-known service and represents 'PM' in decimal.

In postmarketOS we are now able to generate system images with the
correct configuration so that they can boot already using qemu
This commit brings the `pmbootstrap qemu` action.
This command is very handy because you don't have to set all the
qemu parameters, pmbootstrap does it for you.
* device-qemu-vexpress: Added kernel command line according to wiki
* qemu: Added workaround for image writing permissions
* qemu: Added support to launch postmarketOS in a QEMU virtual machine
- Support for emulating these architectures in QEMU: arm, aarch64, x86_84
- Generate QEMU command correctly depending no guest architecture (arm/x86)
- Run QEMU in the same architecture as the host by default
- Refactoring in pmb.parse.arch and pmb.qemu.run
- Raise exception if DTB file or system image are not present
- Display more useful information when something fails (e.g. image not found)
- Run qemu version depending on arch (host or argument), not device configured
* device-qemu-amd64: set deviceinfo_kernel_cmdline to "PMOS_NO_OUTPUT_REDIRECT"
* qemu: added --memory argument to specific guest RAM
* device-qemu-amd64: adjusted deviceinfo_kernel_cmdline (console=tty1)
* Added /etc/network/interfaces for qemu-amd64
* qemu: Added KVM support if /dev/kvm if present
* Specify separate machines for architecture
* qemu: Check if QEMU is installed instead of crashing
* Added graphics driver to qemu-aarch64
- Use arm (as used in qemu) instead of armhf (used in Alpine)
- qemu argument is -dtb
- Follow same style to build the command + arguments
* qemu: Added SSH port redirection: ./pmbootstrap.py qemu -p 2222
