Subject: Lots and lots of potential bugs detected by GCC 14 analyzer

If -fanalyzer is added to config/meson.build than compiler finds lots of potential
problems. (Think of it as free version of Coverity).

The output is quite verbose.
Is it worth putting large N of new bugs into bugzilla or maybe maintainers could take a look.

Full build output is 12M so attaching it.


Quick hack to enable is.
