This is much closer to what we did before with mimetypes. Using a whitelist
turns out to be a bad idea since repositories seem to be randomly filled with
executable images and documents, which trigger the scanner.
In an ideal world the scanner would complain about all of those. For now, just
warn about the possibility of them being hidden binaries.
Initially, the scanner used libmagic which used magic numbers in the file's
content to detect what kind of file it appears to be. Since that library isn't
available on all systems, we added support for two other libraries, mimetypes
amongst them.
The issue with mimetypes is that it only uses the file's extension, not its
actual content. So this ends in variable behaviour depending on what system
you're using fdroidserver on. For example, an executable binary without
extension would be ignored if mimetypes was being used.
We now drop all libraries - mimetypes too as it depends on the system's
mime.types file - and instead check extensions ourselves. On top of that, do
a simple binary content check to find binary executables that don't have an
extension.
The new in-house code without any dependencies doesn't add any new checks, so
no builds should break. The current checks still work:
% fdroid scanner app.openconnect:1029

Import tweaks and tests
This makes the code for `fdroid import` a bit more flexible and adds tests for the first time. It also comments out options in `examples/config.py` that just mirror the defaults to make it clear that they are defaults, and help illustrate other options (this is standard procedure in default config files).
More details in the commit messages.

If for whatever reason the update check results in an older version that we
didn't package, don't "update" to that version if we already packaged newer
versions.

For a bit repo like f-droid.org, it makes sense to standardize on a single
format for metadata files. This adds support for enforcing a single data
format, or a reduced set of data formats. So f-droid.org would run like
this if it changed to YAML:
accepted_formats = ['txt', 'yaml']
Then once everything was converted to YAML, it could look like this:
accepted_formats = ['yaml']
In order to prevent confusion caused by multiple metadata files for a given
app, fdroid will exit with an error if it finds any app metadata file with
the same package ID as one that has already been parsed.
This puts process of setting up the defaults for the internal dict
that represents a parsed app into a single method that is reused for all
metadata formats.
YAML is a format that is quite similar to the .txt format, but is a
widespread standard that has editing modes in popular editors. It is also
easily parsable in python.
The .pickle for testing is a lightly edited version of the real metadata
for org.videolan.vlc:
