Before, lots of pieces of the Android SDK were required for fdroidserver to
operate, like aapt, zipalign, etc. Now, apksigner is the only requirement.

The paths in the config must be strings because they are used in things
like env vars where they must be strings. Plus lots of other places in the
code assumes they are strings. This is the first step to defining the
border of where paths can be pathlib.Path() and where they must be strings.
This job just started failing, but wasn't before:
https://gitlab.com/eighthave/fdroidserver/-/jobs/4060582594
But I look at it, and it looks right that it fails. So how on earth
was it succeeding before? Basically the `os.getenv('ANDROID_HOME')`
returns `None` when `ANDROID_HOME` is not set. It is not set in both the
jobs, so how did it not stacktrace before?
Things like apksigner and @obfusk's tools handle this now.
jarsigner is used in the test, since that's the most common use of
`common.find_sdk_tools_cmd()`.

The current signing method uses apksigner to sign the JAR so that it
will automatically select algorithms that are compatible with Android
SDK 23, which added the most recent algorithms:
https://developer.android.com/reference/java/security/Signature
This signing method uses then inherits the default signing algothim
settings, since Java and Android both maintain those. That helps
avoid a repeat of being stuck on an old signing algorithm. That means
specifically that this call to apksigner does not specify any of the
algorithms.
The old indexes must be signed by SHA1withRSA otherwise they will no
longer be compatible with old Androids.
apksigner 30.0.0+ is available in Debian/bullseye, Debian/buster-backports,
Ubuntu 21.10, and Ubuntu 20.04 from the fdroid PPA. Here's a quick way to
test:
for f in `ls -1 /opt/android-sdk/build-tools/*/apksigner | sort ` /usr/bin/apksigner; do printf "$f : "; $f sign --v4-signing-enabled false; done

If a project uses fdroidserver as a library, then just calls
common.get_apk_id(), it will now work. Before, that project would have had
to include something like `common.config = {}` to avoid a stacktrace.
allowlist and blocklist are much clearer terms with no cultural baggage.
This changes all "whitelist" references to "allowlist", and all "blacklist"
references to "blocklist".
config.yml requires ASCII or UTF-8 encoding because this code does not
auto-detect the file's encoding. That is left up to the YAML library.
YAML allows ASCII, UTF-8, UTF-16, and UTF-32 encodings. Since it is a
good idea to manage config.yml (WITHOUT PASSWORDS!) in git, it makes
sense to use a globally standard encoding.
