This is useful for parsing APK files, which can include packageName,
versionCode, and optionally 7 char signing key ID (i.e. <sig>).
This also can set the packageName and versionCoe for non APK files, so
that it is easy to assign them to metadata files, and to allow for
upgrades by setting the versionCode in the filename.
Google has their own utility for verifying APK signatures on a desktop
machine since Java's jarsigner is bad for the task. For example, it
acts as if an unsigned APK validates. And to check whether an APK is
unsigned using jarsigner is difficult.
apksigner also does the v2 signatures, so it will have to be used
eventually anyway. It is already in Debian/stretch and can be
available in jessie-backports if need be.

The ZIP format allows multiple entries with the exact same filename, and on
top of that, it does not allow deleting or updating entries. To make the
`fdroid verify` procedure failsafe, it needs to create a new temporary APK
that is made up on the contents of the "unsigned APK" and the signature
from the "signed APK". Since it would be possible to give a signed APK as
in the unsigned one's position, `fdroid verify` was not able to update the
signature since it was just adding the new signature to the end of the ZIP
file. When reading a ZIP, the first entry is used.
This makes it so that the final build product can be specified in output=
and it'll work no matter if its an APK or not. This was developed around
the case of building the OTA update.zip for the Privileged Extension. It
should work for any build process in theory but it has not yet been tested.

The start up sequence of processes that are based on the .fdroid.* metadata
is a bit different, so this ensures that the environment variables get
properly initialized in all cases.
This also creates a single function where the environment is set. Before
it was being set in multiple places across multiple files.
This simplifies usage, goes from
build['flag']
to
build.flag
Also makes static analyzers able to detect invalid attributes as the set
is now limited in the class definition.
As a bonus, setting of the default field values is now done in the
constructor, not separately and manually.
While at it, unify "build", "thisbuild", "info", "thisinfo", etc into
just "build".

Sometimes, buildToolsVersion is a kind of gradle macro call, and other
times it is a variable assignment. This regsub pattern now handles both of
those cases.
This is a more flexible approach than testing for the complete SDK and
build-tools up front. This will only test for the commands that are
actually being run, so that if you only have `aapt` installed, you can do
`fdroid update` without errors, but other commands will still give
appropriate errors.
This also makes the build_tools item in config.py optional, it is only
needed if you want to force a specific version of the build-tools.
Just getting into the habit of adding tests to everything that I change...
Also, it should be useful to have an unsigned APK in the test collection,
since `fdroid update` should handle it gracefully and give a warning of
some kind.
