Generally moves all the plugin code into xcomposite-input.cpp and
removes all C++ dependencies.
Migrate as much as possible to xcb from Xlib to enable us to handle
errors and attribute them to the correct callers. This caused many other
knock on issues such as wrongly attributed errors and cleanup code
working incorrectly.
That allows us to use the xcursor-xcb implementation and delete the pure
Xlib implementation. We also add the missing functionality from the Xlib
implementation to the xcb implementation.
Capture glXCreatePixmap errors which occur most commonly on
nvidia+gnome due to nvidia's driver being unable to allocate more than 1
pixmap per window and gnome being the only compositor to read window
data via glx pixmaps.
Fix cleanup after failed glXCreatePixmap that might have leaked pixmaps
and prevented later captures on nvidia drivers for the same reason.
Hardcode short hash length to 9 characters in CI and packaging scripts.
It is not guaranteed that short hashes are the same length across
different platforms or different versions of git. This caused problems
with upload/download action names, as the hashes sometimes didn't match.
Fix the download artifact name in the Windows installer job and the
macOS notarization job to prevent them from failing due to a name
mismatch.
On master branch, client information for Twitch, YouTube and Restream
integration are set as CMake cache variables. The hashes can contain
otherwise "illegal" characters such as backticks which need to be
enclosed in a string, but also cannot be subject to variable
substition.
Using single quotes should fix this.
