* Fix loading the embedded theme and error reporting

We now handle correctly the following situations:

- Empty theme in the settings: fallback to the embedded theme.
- Selected theme doesn't exist: load the first one in alphabetical order like
  before, in addition to that fallback to the embedded theme if there are no
  themes at all.
- Selected theme has QML errors: fallback to the embedded theme and display
  the errors prompting the user to select another one.

This means that in any case we always let the user log in with a theme
embedded into the executable in order to be sure it always exist.

* Make the default cursor themed (sddm#705)

The X root window uses an "X" as the default cursor. To use a themed one,
it has to be set explicitly, e.g. by QML MouseAreas. For themes which do
not have a MouseArea that spans the entire screen, the "X" cursor would
be visible. By setting a cursor in the root QML object, the themed cursor
will be used by default. (https://bugs.kde.org/show_bug.cgi?id=337083)

* Unlock Gnome keyring on login (sddm#711)

Gnome's keyring stores user keys (eg: wifi passwords) encrypted, and uses
a pam module to unlock them at login.

This patch adds `optional` support for the gnome_keyring pam module, so
Gnome can be launched successfully from SDDM. Without this, Gnome will
ask for the users password again after logging in, the first time it needs
to access the keyring, in order to unlock it.

Other display managers as the Gnome Display Manger [1], LightDM [2] and
Enlightment's Entrance [3] already do this.

* Also set QT_IM_MODULE in non testing mode

QT_IM_MODULE is set from a config value, however it currently is only

* Load configuration information from config directories

Our configuration generally consists of user set config options and
distro defined options.

For example, a distro might want to specify a custom theme, but the
user's autostart name can't come from the distro.

Using the same config file leads to problems when upgrading.

This loads configuration from all files in a directory
(/etc/sddm/conf.d) as well as the main config file /etc/sddm.conf
The latter has priority and all writes occur in that file.

* Move EnableHiDPI setting to X11 and Wayland sections

Let's have a different setting depending on the display server.

On Wayland we might have a chance to circumvent bad physical size reported
by some screen while on X11 it's harder because we cannot do that from
QPA, hence a user might want to disable HiDPI on X11 and enable it on
Wayland.

Currently AFAICT the /etc/X11/Xsession script in Ubuntu is expecting 1 and only 1 arguments as the running command, as showed as the following fraction of /etc/X11/Xsession.d/20x11-common_process-args:

```sh

Currently SDDM runs the Xsession script without quoting the second argument, which causes all xsessions that Exec key contains command-line arguments(like Unity(gnome-session --session=ubuntu)) causes Xsession to bail out with message "Xsession: unsupported number of arguments (2); falling back to default session."

VirtualTerminal::chVt code inspired by chvt utility.

This fixes the following bug:
1. Login user A
2. Switch user
3. New session: login user B
4. Switch to user A
5. Logout user A
=> Virtual terminal is not switched to session of user B,
   but shows a text terminal login or is blank.

This code works with Xorg sessions. Wayland sessions seem
to have other problems when logging out, this fix does not
address these.

* Integrate the VT switching fix into existing jumpToVt():
Do not handle the VT switching yourself by setting VT_PROCESS,
but let the kernel switch VTs automatically (VT_AUTO).
After session end there is no controlling process anymore
which could send the VT_RELDISP ioctl to release the switch.

* Check for getpwnam_r error status. Fixes sddm#489

* greeter: Use Qt command line parser

Do not reinvent the wheel with a command line parser.
Restructure the code so that GreeterApp no longer need to
parse arguments itself.

* Add Namespaces setting

This option holds a comma-separated list of paths bound to Linux namespaces to
enter with setns() before starting the user session.

The main intention is to let user sessions start in a protected network
namespace, while the display server remains in the initial network namespace to
talk to udev, and udev remains in the initial network namespace to talk to
systemd.

[ChangeLog][General] Add "Namespaces" setting under "General" to enter specified
Linux namespaces before starting the user session

* Update man page about default path

Closes: sddm#958

* Fix platform detection for EnableHiDPI

We can't use QGuiApplication before it's constructed, so find out which
platform is requested ourselves.

Fixes sddm#894

* Remove trailing spaces

* Fix build

* UserModel: optimize filtering out duplicate users (sddm#995)

Instead of using naive approach of trying to detect duplicates when
inserting a new user into the list of users, which is O(n^2) complexity,
let's filter them out after the fact, which is much more efficient on
real-world data.

With this change time to load user list in our environment (over 500000
account entries) is reduced from over 1 hour to about 2 seconds.

* UserModel: fix filtering out duplicate users (sddm#998)

std::unique() is "interesting": it modifies the container, rearranging
elements in it, but does not reduce the size of the container, so there
are invalid elements at the end that have to be erased explicitly.

* Do not install sddm.conf by default (sddm#996)

sddm.conf overrides the configuration from the conf.d
directories and we don't want that.

SDDM still reads it if users keep the file after an
upgrade, but since the introduction of conf.d directories
we shouldn't install sddm.conf by default.

[ChangeLog][Daemon] Do not install /etc/sddm.conf anymore

* Fix build with Qt < 5.10: Use QString instead of QLatin1String (sddm#1001)

QLatin1String only got more QString-like with Qt 5.10, so we can't use
those methods.

* Add Icelandic Translations (sddm#1002)

Add Icelandic translation file.

[ChangeLog][Translations] Add Icelandic

* UserModel: optimize setting of default user icon (sddm#999)

Instead of checking for existence of theme-specific icon and re-creating
string literals every time we add a new user to the list, do it once.
It helps in large organizations with a lot of users.

* adding Bangla translation (sddm#1006)

* Skip theme for greeter call if none is set

- fix loading default theme if none is set

* Honor PAM's ambient supplemental groups. (sddm#834)

When compiled with USE_PAM, prefer a combination of
getgroups(3) and getgrouplist(3) for ambient and user
groups, respectively, to initgroups(3).

This way, groups injected into the PAM environment
by means of pam_groups.so aren't ignored.

* XorgDisplayServer.cpp: Check pipe output if there is nothing (sddm#1021)

X server may break down without writing a display number
to the pipe specified by '-displayfd'. SDDM should exit explictly
in such cases. Otherwise, it will get a null string for display number,
which leads /usr/bin/xauth gets bad parameters, i.e.

    /usr/bin/xauth: (stdin):1:  bad "remove" command line
    /usr/bin/xauth: (stdin):2:  bad "add" command line

* Update Korean translations (sddm#1025)

* Fix build with Qt 5.11 (sddm#1024)

qt5_use_modules was deprecated for quite some time and got finally removed.

* Fix sddm-greeter exit if it can't connect to the daemon (sddm#1016)

* Fixed typo that prevents ConsoleKit to be detected (sddm#1027)

* Don't add session files with NoDisplay=true to SessionModel (sddm#1029)

Same treatment as for Hidden. SessionModel is not used for autologin,
so for all intents and purposes it's the same. If a user logged in with
a NoDisplay=true session, the last session index will be incorrect, but
IMO that's the intended behaviour of NoDisplay.

* Fix missing include in HelperApp.cpp

SDDM did not compile on musl libc, since HelperApp.cpp was using
gettimeofday(), which is defined in <sys/time.h>, without importing it.

[ChangeLog][Helper] Fix build with musl libc.

* add new translations

* Fix authentication when reusing an existing session

- Check the success value before unlocking the session
- Don't attempt to use the nonexistant "sddm-check" PAM service

* Adds sourcing of /etc/profile to fish

This ensures the right paths are set by upstream apps that use the
/etc/profile(.d) method for setting paths, for example xdg or snap.

[ChangeLog][Xsession] Source /etc/profile for fish too

Closes: sddm#879

* Fix switchToGreeter not available without logind

Seats can't be created until SeatManager's signals are
connected to the DisplayManager, or the latter won't see
them and switchToGreeter doesn't work. So split SeatManager
initialization from its constructor and call initialize it
only after all connections have been set up in DaemonApp's
constructor.

With logind there may have been enough delay before seats
got actually added so things would work, but it's still
cleaner to fix the order.

* Remove correct view when a screen is removed

This connect was done for all views so previously when any screen was
removed all views would be.

* Bump to 0.18.0

* Handle session re-use in the same slot as everything else

m_auth is connected to ::authentication in the constructor so use of a
second connect is really weird and runs in an undetermined order

QMap sorts it's keys, but sorting by memory address makes little sense.
Using QHash instead, which provides faster lookups and don't sort the keys.

The same rationale applies to QMultiMap which is just a  is a convenience
QMap subclass that provides multi-valued maps.
