Reported by Achim Patzner <noses@noses.com>
This rewrite is mainly to adopt new interface for Qubes 4.x.
Main changes:
- change language from bash to python, introduce qubesagent python package
- support both nftables (preferred) and iptables
- new interface (https://qubes-os.org/doc/vm-interface/)
- IPv6 support
- unit tests included
- nftables version support running along with other firewall loaded

This have many advantages:
- prevent XSS (QubesOS/qubes-issues#1462)
- use default browser instead of default HTML viewer
- better qrexec policy control
- easier to control where are opened files vs URLs
For now allow only http(s):// and ftp:// addresses (especially prevent
file://). But this list can be easily extended.

No functional change.
This will make it easier to switch the tool (without recompiling
vm-file-editor), or even use differrent tools depending on some
conditions.

Many USB controllers doesn't play nice with suspend when attached to PV
domain, so unload those drivers by default. This is just a configuration
file, so user is free to change this setting if his/shes particular
controller doesn't have such problem.

DNF in Fedora 22 uses python2, but in Fedora 23 - python3. Package both
of them, in separate packages (according to Fedora packaging guidelines)
and depend on the right one depending on target distribution version.

Explicitly block something like "curl http://10.137.255.254:8082" and
return error page in this case. This error page is used in Whonix to
detect if the proxy is torrified. If not blocked, it may happen that
empty response is returned instead of error. See linked ticket for
details.

Apparently unmanaged devices are loaded only from main
NetworkManager.conf. Exactly the same line pasted (not typed!) to main
NetworkManager.conf works, but in
/etc/NetworkManager/conf.d/30-qubes.conf it doesn't.
BTW There was a typo in option name ("unmanaged_devices" instead of
"unmanaged-devices", but it wasn't the cause).
This reverts commit 6c4831339c.

Because those services do not yet support being restarted.
Extended variable `$nrconf{override_rc}`, i.e. packages only reported to need
restart, but blacklisted from default/suggested automatic restarted with
`qubes-core-agent` and `qubes-gui-agent`.
See also `$nrconf{override_rc}`:

Each time some arbitrary package was installed using dpkg or apt-get, the update notification in Qubes VM Manager was cleared.
No matter if there were still updates pending. (Could happen even after the user running `apt-get dist-upgrade` in case of package manager issues.)
No longer clear upgrade notification in QVMM on arbitrary package installation.
Check if upgrades have been actually installed before clearing the notifications.

Since /lib/modules is not mounted read-only anymore (only a selected
subdirectory there), it is no longer required to prevent kernel package
installation. Even more - since PV Grub being supported, it makes sense
to have kernel installed in the VM.

Initramfs created in TemplateVM may be used also in AppVMs based on it, so
technically it is different system. Especially it has different devices
mounted (own /rw, own swap etc), so prevent hardcoding UUIDs here.

Do not modify main /etc/NetworkManager/NetworkManager.conf as it would
cause conflicts during updates. Use
/etc/NetworkManager/conf.d/30-qubes.conf instead.
Also remove some dead code for dynamically generated parts (no longer
required to "blacklist" eth0 in VMs - we have proper connection
generated for it). It was commented out for some time already

Initial size of those tmpfs-mounted directories is calculated as 50% of
RAM at VM startup time. Which happen to be quite small number, like
150M. Having such small /tmp and/or /dev/shm apparently isn't enough for
some applications like Google chrome. So set the size statically at 1GB,
which would be the case for baremetal system with 2GB of RAM.

* origin/pr/31:
Fixed /etc/pam.d/su.qubes. (Moved line 'auth sufficient pam_permit.so' up. May not be low '@include' lines.)
- Prevent 'su -' from asking for password in Debian [based] templates. Thanks to @unman and @marmarek for suggesting the fix! Fixes https://github.com/QubesOS/qubes-issues/issues/1128. - Changed 'ifeq (1,${DEBIANBUILD})' to 'ifeq ($(shell lsb_release -is), Debian)' to make the build work outside of Qubes Builder as well.

Usage of _static_ files (dropins) to override some of autostart entries
(enable/disable them in appropriate VM types) is much simpler and less
error prone than automatic generators.
Handling code is implemented in qubes-session-autostart, which is called
from qubes-session.

Fedora now needs this sudoer rule. Allows sudo to keep the `QT_X11_NO_MITSHM` ENV
variable which prevents MIT-SHM errors for Fedora and Debian when running a QT
application:
`Defaults env_keep += "QT_X11_NO_MITSHM"`

- need to sync with upstream changes (configuration path etc)
- conflicts resolution on updates
- lack of iptables --wait, which causes firewall fail to load sometimes

qubes-desktop-file-install is called by qubes-triggers-desktop-file-install. It's
arguments are based on the Gnome desktop-install-file utility to allow it to be replaced
by same. Currently the Gnome utility can not be used since it automatically validates
the .desktop entry files with no option to skip validation and will fail on some third
party .desktop files that are not formed properly.
A single trigger script is shared between Fedora, Debian. This script is used by the
package managers triggers and will copy original .desktop files from `/etc/xdg/autostart`
to `/usr/share/qubes/xdg/autostart` and modify the OnlyShownIn / NotShownIn, etc. The
original .desktop files are left untouched and left in place.
Qubes modifies the XDG_CONFIG_DIRS to first include the `/usr/share/qubes/xdg`
directory (XDG_CONFIG_DIRS=/usr/share/qubes/xdg:/etc/xdg).
If a package gets removed, it's desktop entry is also removed from the /usr/share/qubes/xdg
directory.
'qubes-desktop-file-install' options:
--dir DIR Install desktop files to the DIR directory (default: <FILE>)
--force Force overwrite of existing desktop files (default: False)
--remove-show-in Remove the "OnlyShowIn" and "NotShowIn" entries from the desktop file (default: False)
--remove-key KEY Remove the KEY key from the desktop files, if present
--set-key (KEY VALUE) Set the KEY key to VALUE
--remove-only-show-in ENVIRONMENT Remove ENVIRONMENT from the list of desktop environment where the desktop files should be displayed
--add-only-show-in ENVIRONMENT Add ENVIRONMENT to the list of desktop environment where the desktop files should be displayed
--remove-not-show-in ENVIRONMENT Remove ENVIRONMENT from the list of desktop environment where the desktop files should not be displayed
--add-not-show-in ENVIRONMENT Add ENVIRONMENT to the list of desktop environment where the desktop files should not be displayed
Restore support for older yum: no --downloadonly option, so use
yumdownloader.
Also add some a code to handle some Debian quirks - especially default
rpmdb location in user home...
- Use copy-in for debian-quilt package in Makefile.builder instead of hook (to be removed) in Makefile.debian

Instead of directly using Exec= line, parse the file (at the launch
time) with Gio library. The main reason for this change is to handle
Terminal= option, but generally this approach should be more
bulletproof, especially when some fancy options are present in desktop
files.
It would be called by qvm-sync-clock instead of 'date' directly. This
gives a lot of flexibility - VM can control whether it want to sync time
this way. For now slight corrections (+-2sec) are ignored to not cause
problems by frequent time changes. But it can be easily extended to
refuse time sync when some other mechanism is used.
It looks to be related to this report:
https://bugzilla.redhat.com/show_bug.cgi?id=1088619
Workaround idea was from comment 37.
The hanging process in Qubes VM is most likely dconf-service, but there
is a lot of possible causes. To start with a non-standard method of
accessing the X session (no real login manager, processes started by
qrexec-agent). So instead of wasting a lot of time on digging through
gnome services, simply shorten the stop timeout - the processes would be
killed anyway.
Since d660f260b8 icon is hidden during VM
startup for non-netvm. Because qubes-session handles tasks sequentially,
move that one earlier to not scary the user with ghost icon.
This time it is for cups, which have socket-based and path-based
activators. When activator tires to start the service which is disabled
by condition file it enters infinite loop (as service wont start, but
will not report an error).
MIME-info database contains multiple entries for *.png, namely image/png
and image/x-apple-ios-png. The later one doesn't have associated handler
program, but this one is selected by mimeopen tool.
Not sure how this tool should behave in case of multiple matches (IOW is
it a bug in File::MimeInfo perl module used by mimeopen). Instead of
switching to different tool, which probably will break other files
(check #423), add override for this particular file type.
This libs are required by both dom0 and VM so it's better to have it
separately. Previously in VM it was separate package, but dom0 have them
embedded in qubes-core-dom0, but qubes-core-vm-libs package was used to build
qubes-gui-dom0. Now we do not build all packages for all distros (especially do
not build core-vm package for dom0 distro, so gui-dom0 build fails), so make it
explicit which package is needed by which system.
Some packages depends on kernel (ex fuse, pulseaudio), but kernel in VM is
managed by dom0. Any hack like exlude or so on will break some things, so
install empty placeholder package to fulfill dependencies.
Modify VM packages to:
- do not conflicts
- starts services if its VM type need it
Added core-proxyvm (firewall) and core-commonvm (common parts) packages.
