Since libloc is currently only using mmap() to map any databases into
memory, all mapped address range needs to be page aligned.

In the past, every database was aligned to a 4k page boundary. Some
architectures use 64k pages by default which could therefore not open
the database.

This patch changes the alignment to 64k which should hopefully be a
good common denominator. However, older database cannot be opened.

If we would ever have to support an architecture which's page size
is not evenly fitting into 64k, we will have to implement an
alternative to mmap.

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.

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.
