These hacks were added in 70aaf7ea to continue supporting old index
versions stored on disk, which was necessary to upgrade v14 to v25
for 2.11->2.12. Now that stable-2.12 has been cut, we can remove
support for this.
Get rid of the core-and-backward-codecs target and just use core. A
side effect of this change is that pack_war.py would now fail, since
it expects each jar that goes in lib/ to have a unique name, and there
is already a "core" target in MINA. Prefix all the lucene targets with
"lucene-" to get it working.
