Throughout the code, variables named "app" are instances of the App class.
In this case, this is related, but it is a dict not an App instance, since
it is being prepared for including in the index-v1.json.
If there was a global default on a machine that was something other than
'master', these things would crash with:

The builder should check the `AllowedAPKSigningKeys` at build time, so
that the CI can check if somebody gives a wrong value that doesn't match
a compared RB binary. In the event it fails, it gives useful
information, and in the event it succeeds, it makes it clear that this
build has verification back to the developer's original key.
Also, add tests for this to the test suite.
Per fdroiddata!12911 the linter should error out if somebody uses `binary` or
`Binaries` without supplying an `AllowedAPKSigningKeys`.
There are two reasons for this:
- Security: this allows full verification that the binaries built match
the developers, not just what happened to get uploaded onto github at
some later point in time.
- Reliable updates: if the signing key changes, users won't be able to
update, so this is something we should learn about when upstreams send
in commits changing their signing key, rather than just leaving it to
chance.
I profiled this with timeit and a dict with 1000000000 items, and this is
the time difference:
with_equals: 0.8466835720173549
with_is: 0.8536969239939936
with_old: 1.4458542719949037
I also compared using `==` and `is`, and `==` was slightly faster.
I tried to get this to indent the .yaml files properly so yamllint defaults
work with tests/metadata/dump/*.yaml, but it didn't take for some reason:
yaml.indent(mapping=4, sequence=4, offset=2)
This function is only used in checkupdates, and removing it from the App
class moves the App class one step closer to being a plain dict, which is a
more Pythonic style.
