mitigated several compiler warnings / suppress compiler warnings in CI where we don't care about them (#5497)
There's no need to generate any warnings in the CI unless we react on
them.

MathLib: renamed `to{U}LongNumber()` to `toBig{U}Number()` (#5503)
The name was misleading as it was actually a `long long` and also if we
ever move to an (optional) 128-bit value it wouldn't even less fitting.
We should name it to match our alias type.

Fix copy-paste-error (#5444)
This is a warning we found during static analyis with CodeSecure
CodeSonar.

It flagged a suspicious copy-paste error, where it finds code that seems
to have been copied from another location, with some, but not all,
variables substituted.

Unclear to me if this truly is a problem, or intentional, but I wanted
to provide the feedback as I am not sure how to test this.

Lines 5614 to 5619 in lib/symboldatabase.cpp are a copy from 5597-5602
with vartok replaced by valuetok, except for line 5616

utils.h: added `startsWith()` and started using it (#5381)
This makes the code much more readable. It also makes it less prone to
errors because we do not need to specify the length of the string to
match and the returnvalue is clear.

The code with the bad returnvalue check was never executed and I added a
test to show that.

sped up `Tokenizer::dump()` (#5009)
Scanning the `cli` folder with `DISABLE_VALUEFLOW=1` `Tokenizer::dump()`
will consume almost 25% of the total Ir count when an addon is
specified. This is mainly caused by the usage of `std::ostream`.

Encountered while profiling #4958.

Fix use-after-free crash when using --clang (#5367)
Still ran into an assert failure in `Tokenizer::hasIfdef()`, since some
checks assume that the tokenizer is always present. Seems like
clangimport is yet another rogue under-tested feature...

fixed #6316 (Use std::to_string() in place of MathLib::toString() ...) - deleted default implementation of `Mathlib::toString()` (#5341)
It was also used inconsistently and seemed to imply there is some
special handling which wasn't the case. It was just an alias for
`std::to_string()` for non-`double` types. So there was no need for it.

cleaned up includes based on include-what-you-use / iwyu.yml: updated to yet another distro to get the latest version and updated the Chaotic-AUR key (#5267)
This is a mess. The version is AUR is still outdated and also doesn't
install anymore. Fedora 38 carries the latest version of it so use that
now. Keep the old steps in case we need to switch again in the future.
