implemeted support for using a smartcard for the repo signing key
This changeset implements using a smartcard (HSM) as the keystore for the signing key. It also fixes lots of little bugs in the `fdroid init` process.
This assumes that the smartcard is already setup with a signing key. init
does not generate a key on the smartcard, and skips genkey() if things are
configured to use a smartcard.
This also does not touch APK signing because that is a much more elaborate
question, since each app is signed by its own key.
Previously, `fdroid init --keystore /tmp/foo` expected the keystore to
exist, or it quit with an error. But I've changed my mind, I think it is
useful to have it generate a new keystore at that location if it does not
exist. For example, in tests/run-tests.sh. It still will not clobber an
existing file at that location.
These options are needed to configure Java's keytool and jarsigner to use
a Hardware Security Module aka HSM aka smartcard. The defaults provided
are meant to make things work as easily as possible.
The defaults are set in config.py and are often commented out. Before, the
regex would only change the value, but leave it commented out. Now, it
will also uncomment it.
hashlib uses some magic to load whatever is built into the local openssl.
pylint gets confused by this, so we need a pylint plugin to trick pylint
into thinking everything is good.
setuptools wants to stick any relative install path in data_files into the
.egg package. Things are not setup to use the egg now. We might want to
consider using sticking files into the egg via pkg_resource in the future.
Using `python setup.py install`, things in non-standard python paths need
to be added to the MANIFEST in order for them to be included and installed.
There might be a better solution for this, but I haven't found it.
FDroidPopen() does not have a way to send to stdin, so we will use the
password file for now. In the long run, at least the keypass should always
be sent via stdin rather than via a file. Ideally, storepass would be too,
but if they are different, then storepass is less important.
This also makes the file layout in git basically the same as the installed
file layout, using an examples/ dir. I'm not sure if config.buildserver.py
is an example conf file, or a conf file that is actually in use, so I did
not move it.
