Add asynchronous filereader, fix python3 lockups
with the current implementation of AsynchronousFileReader with Python 3 FDroidPopen deadlocks with 100% CPU-utilization
The code is from https://github.com/soxofaan/asynchronousfilereader
I hope the MIT-Licence makes no problems

Added support for gradle flavor specific dependencies in usual suspects check
When you have flavor specific dependencies in your project, you specify them in the build.gradle file with a prefixed *compile* command:
```
compile 'normal dependency'
myflavorCompile 'only for myflavor'
```
The usual suspects check just searches for some often used library names in the whole build.gradle file. I added another condition, so dependencies for not build flavors are not checked.

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.
