This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
...`__attribute__((__noreturn__))`
This is more inline with the definition in glibc's version of the file,
and stops clang from complaining about it originally not being declared
as `[[no_return]]`.
If a test is supposed to fail during parse or early phase we can stop
after parsing. Because phases in modules are not as clear we don't skip
the other parts for modules.
When running a larger set of tests in Serenity the runner would
otherwise trigger a lot of crash reporters. This would then in turn lead
to memory starvation causes more crashes.
We also protect against recursive assert failures, for example due to
being out of memory.
With this change the runner now compiles and runs on Serenity :^).
Since setitimer is not implemented in Serenity we use alarm which
triggers SIGALRM after the timeout. We also don't use a signal handler
as we are doing things that serenity doesn't like/doesn't allow.
Linux dealt with allocating and writing in a signal handler but it is
undefined, so instead we just let the process die by SIGALRM.
This means we instead of reading the output can detect timeouts by
checking how the process died.
For now this is a lagom only application as it is not compatible with
serenity in its current state.
The only change is that it is released under a different license with
permission from all the authors.
