Pablo Castellano c855ee095b Qemu support for the QXL driver and SPICE (#481)
* 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.

Pablo Castellano 49b35ad32d Close #226: Launch postmarketOS in a qemu virtual machine (#350)
Thanks to Pablo Castellano and Martijn Braam!
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

Oliver Smith 51bdc24315 Properly rebuild/install packages when something changed (Fix #120, #108, #131) (#129)
TLDR: Always rebuild/install packages when something changed when executing "pmbootstrap install/initfs/flash", more speed in dependency resolution.
---
pmbootstrap has already gotten some support for "timestamp based rebuilds", which modifies the logic for when packages should be rebuilt. It doesn't only consider packages outdated with old pkgver/pkgrel combinations, but also packages, where a source file has a newer timestamp, than the built package has.

I've found out, that this can lead to more rebuilds than expected. For example, when you check out the pmbootstrap git repository again into another folder, although you have already built packages. Then all files have the timestamp of the checkout, and the packages will appear to be outdated. While this is not largely a concern now, this will become a problem once we have a binary package repository, because then the packages from the binary repo will always seem to be outdated, if you just freshly checked out the repository.

To combat this, git gets asked if the files from the aport we're looking at are in sync with upstream, or not. Only when the files are not in sync with upstream and the timestamps of the sources are newer, a rebuild gets triggered from now on.

In case this logic should fail, I've added an option during "pmbootstrap init" where you can enable or disable the "timestamp based rebuilds" option.

In addition to that, this commit also works on fixing #120: packages do not get updated in "pmbootstrap install" after they have been rebuilt. For this to work, we specify all packages explicitly for abuild, instead of letting abuild do the resolving. This feature will also work with the "timestamp based rebuilds".

This commit also fixes the working_dir argument in pmb.helpers.run.user, which was simply ignored before.

Finally, the performance of the dependency resolution is faster again (when compared to the current version in master), because the parsed apkbuilds and finding the aport by pkgname gets cached during one pmbootstrap call (in args.cache, which also makes it easy to put fake data there in testcases).

The new dependency resolution code can output lots of verbose messages for debugging by specifying the `-v` parameter. The meaning of that changed, it used to output the file names where log messages come from, but no one seemed to use that anyway.

Make it easier to find the output of failed commands in the log
...by adding a ^^^^^^^^... line right below the failed command's output.

Debian Jessie/Python 3.4 support for the most part (#6)
* automatically find the chroot binary on Debian, even if it is not
  in the user's PATH
* don't use subprocess.run anymore (remove related testcase, that explicitly
  checked for subprocess.run usage, and used recursive globbing, another
  post 3.4 Python feature, for the checks. A similar case can be added in the
  future, but right now it's more important to get Debian 3.4 working and all
  PRs are reviewed anyway.)
* pytest fixtures: don't use the newer "yield" feature, as this is only
  supported in a newer version of pytest, than provided on Debian Jessie

From manually testing, most stuff works in Debian Jessie. However, the
testsuite does not run through - creating an empty .tar.gz with Python
fails for some reason (this is done in test_apk_static.py).
