apt-0.5.15lorg3-pre3

I'm starting to get a feeling there are going to be more than just a
couple of these -pre versions... Anyway, here goes apt-0.5.15lorg3-pre3:
http://laiskiainen.org/apt/testing/apt-0.5.15lorg3-pre3.tar.bz2

Changes since pre2:
- Memory usage is a LOT lower now despite fileslists.xml processing, due
to using xmlTextReader so only files for one package are in memory at a
time instead of holding the whole damn list in memory. Also some earlier
memory leaks have been cleaned up, and blank XML nodes aren't parsed
anymore (thanks to Ralf Corsepius for the hint) futher reducing memory
use.
- Fixes related to the XML handling wrt the blank XML nodes from Ralf
- Small optimization to avoid needless jumping around in the XML files.

Unfortunately I haven't yet found the cause to the occasional "Resolve
generated breaks" errors so that one can still occur with this
version :-/
