This is desirable mainly because libpng is maintained and pnglite is
not. pnglite was last updated in 2007 (15 years ago) and probably has a
lot of security vulnerabilities.
libpng is an actively maintained library also used by browsers like
Firefox or Chromium, so it's less likely to contain security
vulnerabilities, also it's more likely to be packaged by Linux
distributions.
See also Jupeyy's explanation in
https://github.com/ddnet/ddnet/issues/4294 for why we want to ignore
this:
> sadly components have no OnDestruct on anything like that
> so aslong it doesn't actually leak it's just non destructed memory
So it's something we allocate once for the entire client lifetime from
my understanding.

The following packages have unmet dependencies:
mariadb-server : Depends: mariadb-server-10.3 (>= 1:10.3.34-0ubuntu0.20.04.1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Previously, it would not error when tests failed to build or run.
Powershell (at least on CI) apparently only cares about the last exit
status, so separate running the server from running the tests.
Fixes#3057.

The actual work will be fixing those or at least
NOLINT(clang-analyzer-optin.cplusplus.VirtualCall) them so we can enable
this. Disable checks that we don't want.
Exclude external directory from clang-tidy.
Add libnotify support for linux client
Also unify notification management
Make libnotify mandatory for the client. It is installed on 100% of Arch
Linux systems and on 70% of Debian systems. I'd guess the remaining
Debian systems are servers.
Detect dependent libraries of `libnotify` using `pkg-config`. Remove
library-specific code from the game module. Decrement refcount for
libnotify notification object before leaving the function.
