This is a proof of concept patch set containing the changes needed to
make the current CI jobs succeed with cpp_std=c++20.

There is still at least one issue that seemingly only appears in C++20,
and which needs more analysis and testing: https://gitlab.freedesktop.org/camera/libcamera/-/issues/267

Barnabás Pőcze (5):
  gstreamer: Add `-Wno-volatile` for GCC
  meson: Ignore `Wredundant-move` with GCC 11 and above
  libcamera: base: log: Ignore deprecations
  treewide: Use character literal instead of string in some cases
  meson: Switch to C++20
