When importing source data fails for one source, we won't import
anything at all.

This patch changes that behaviour so that we will import all data one
after the other but continue if there was a problem with one source.

This patch changes the order of some operations and drops a few
redundant ones (potentiall).

That should allow us to parse blocked data faster.

All imports should have been conducted in one large transaction so that
we can remove any previous data.

This was not the case because of an indentation issue and could have
caused that the transaction was commited without all data being
successfully re-imported.

The downloader used to open a connection to the web server hosting our
content which would have been decompressed (if necessary) on the fly and
also been parsed on the fly so that it could have been fed into the
database easily.

Some webservers do not seem to be patient enough to keep the connection
open if things take a little bit longer than usual. That caused the
import to fail.

This patch changes the behaviour that we would download all content
first, store it locally, and then start processing it.

The current way of truncating all override data straight away leaves us
with no data at all, should a source turn out to be unreachable or
returning bogus files (yes, Cloudflare, I _am_ looking at you).

It is therefore better to only delete data we know to have a valid
replacement for, rather than just dropping the source altogether.

For the ipset format, we will rewrite the header after we know the total
number of entries that have been written in order to optimise the hash
table.

When the output stream isn't seekable, we cannot write the header again
which is being fixed in this patch.

In order to run the test suite, we need to make the Python module
loadable from the build directory so that we first of all test the right
code and that it just works without running "make install" first.

The prefix is being stored as a total number of bits now since it is
easier for any bitwise maths later. This is however causing an incorrect
prefix being computed when splitting a network into two subnets for
IPv4.

To get the correct prefix, loc_network_prefix must be called.

This is a performance improvement when exporting networks flattened. For
the subnet search, we allocate an empty list many times which is often
not required.

This patch changes this behaviour that (if needed) the lists will be
allocated and will stay around and cleared if necessary.

This patch moves the subqueries out of the large query, so that the
database will materialize them for faster lookup.

We also drop the "UNION ALL" and replace it with just "UNION" because we
do not want any duplicate networks. That will save us many iterations
later on.
