We weren't meant to have multiple contexts and mainloops, but we had one
for each opened device and the hotplug detection thread. Instead, use
pa_threaded_mainloop, which can be shared between threads and objects, and
a single context (which, according to the PulseAudio documentation, is
usually meant to be a singleton that represents a global server connection,
possibly with multiple streams hung on it).
Now instead of polling in a loop, threads will block until the
threaded_mainloop runs a callback, and the callback will fire a signal to
unblock the thread.
Prior to this, the code upset ThreadSanitizer, as Pulse has some unprotected
global resource that each mainloop/context would touch.

SDL mutexes are always recursive in modern times, so no need to check this,
plus the test triggers a false-positive on ThreadSanitizer.

There are many toolkit specific ways to set a font DPI in X11 desktop
environments. The primary approach of reading a Gnome specific setting
from the portal is ok, it will work on Gnome and on Plasma most the
time.
The current fallback GDK_SCALE is less great; it's an internal GTK
setting relating to the mapping of logical pixels to device pixels
within the toolkit, it's a developer setting for GTK devs. We were
instructed within Plasma to not set this as it caused issues.
Xft.dpi in xresources is a good universal fallback, it's very dated to
the point that it works in clients like xterm, Qt on X11 uses it in our
font DPI path.
Ideally we'd detect these as "joysticks" (or more generally, gaming
controllers), but in most cases their evdev flags are indistinguishable
from an accelerometer or gyro, so the only way to achieve this would be
a table of known devices that doesn't currently exist.
One exception is the one that reports a THROTTLE axis and TRIGGER, THUMB
buttons, which would be reasonable to detect via the joystick heuristic.

There are some devices for which SDL's device classification heuristic
is known not to give the ideal result. Add a way to incorporate these
into our test data, so that when the heuristic is improved we can
detect them as their intended device type, without making the test fail
before that has been implemented.

Re-writes clipboard data handling in X11 to an on demand approach where
data can be produced on request instead of storing it in X11 properties
on the window.
Primary selection has been changed to mimic this behavior even though
it's only possible to use it for text as of now.
Ensure that incoming touch events originate from valid surfaces owned by SDL and have proper window data before forwarding them to the touch subsystem, or the window focus pointer that is sent with the event may not be a pointer to an SDL window.
Additionally, ensure that allocated touch events are always cleaned up on exit.
- SDL_MaximizeWindow, MinimizeWindow, SetFullScreenWindow, etc are not meant to show the window if it isn't currently visible, but on some platforms
(e.g. Windows) it isn't possible to set this state without also showing the window so cache the flags in a pending_flags field until SDL_ShowWindow is
called. Then replay the pending flags through ApplyPendingFlags (hoisted out from SDL_FinishWindowCreation).
If the text-scaling-factor setting is available via D-Bus, add a listener and update the content scale values for the displays if the value is changed during runtime.
Factors out the D-Bus message pump from the system theme detection code to the general D-Bus code, as it's now used for more purposes than just the system theme.
Expose the text scaling factor (aka the global scale factor on KDE) as the display content scale value so applications can scale themselves as necessary.
If D-Bus is unavailable or retrieving the setting fails, fall back to trying the legacy GDK_SCALE envvar before reverting to the default 1.0 value.
