In 7c5e30daaa, the focus was "only" on
Userland/Libraries/, whereas this commit cleans up the remaining
headers in the repo, and any new badly-formatted include.
A mistake I've repeatedly made is along these lines:
```c++
auto nread = TRY(source_file->read(buffer));
TRY(destination_file->write(buffer));
```
It's a little clunky to have to create a Bytes or StringView from the
buffer's data pointer and the nread, and easy to forget and just use
the buffer. So, this patch changes the read() function to return a
Bytes of the data that were just read.
The other read_foo() methods will be modified in the same way in
subsequent commits.
Fixes#13687
Apologies for the enormous commit, but I don't see a way to split this
up nicely. In the vast majority of cases it's a simple change. A few
extra places can use TRY instead of manual error checking though. :^)
As per previous discussion, it was decided that the Stream classes
should be constructed on the heap.
While I don't personally agree with this change, it does have the
benefit of avoiding Function object reconstructions due to the lambda
passed to Notifier pointing to a stale object reference. This also has
the benefit of not having to "box" objects for virtual usage, as the
objects come pre-boxed.
However, it means that we now hit the heap everytime we construct a
TCPSocket for instance, which might not be desirable.
