'else' is linked to the hidden 'if' statement in the macro instead of the

Fix this by never leaving un-finished if-statements in
SD_HWDB_FOREACH_PROPERTY(). We simply inverse the if() statement and
explicitly add an 'else'-branch. This way, the statement is closed and all

and got a candidate for the next entry. And we are considering to look
into another journal file because it may contain an entry that is nearer
to the current location than the candidate.

We should skip the whole journal file if we can tell by looking at its
header that none of its entries can precede the candidate.

journal: optimize iteration: skip whole files behind current location

Interleaving of entries from many journal files is expensive. But there
is room for optimization.

We can skip looking into journal files whose entries all lie before the
current iterating location. We can tell if that's the case from looking
at the journal file header. This saves a huge amount of work if one has
many of mostly not interleaved journal files.

On my workstation with 90 journal files in /var/log/journal/ID/
totalling 3.4 GB I get these results:

$ time ./journalctl --since=2014-06-01 --until=2014-07-01 > /dev/null

The high "sys" time in the original was caused by putting more stress on
the mmap-cache than it could handle. With the patch the working set
now consists of fewer mmap windows and mmap-cache is not thrashing.
