Philip Withnall 00bfb3ab44 tree: Fix various typos and outdated terminology
This was mostly machine generated with the following command:
```
codespell \
    --builtin clear,rare,usage \
    --skip './po/*' --skip './.git/*' --skip './NEWS*' \
    --write-changes .
```
using the latest git version of `codespell` as per [these
instructions](https://github.com/codespell-project/codespell#user-content-updating).

Then I manually checked each change using `git add -p`, made a few
manual fixups and dropped a load of incorrect changes.

There are still some outdated or loaded terms used in GLib, mostly to do
with git branch terminology. They will need to be changed later as part
of a wider migration of git terminology.

If I’ve missed anything, please file an issue!

# be configurable enough for our coding style. Thats why this CI check is OK
# to fail: the idea is that people can look through the output and ignore it if
# its wrong. (That situation can also happen if someone touches pre-existing
# badly formatted code and it doesnt make sense to tidy up the wider coding
# style with the changes theyre making.)
