Orphaned: sphinxbase, sphinxtrain, and cmusphinx3

I have orphaned three projects, and thus they need a new maintainer:

sphinxbase, a common library for CMU Sphinx voice recognition

sphinxtrain, Carnegie Mellon University's open source acoustic
model trainer. It contains the scripts and instructions necessary
for building models for the CMU Sphinx Recognizer.

cmusphinx3, CMU's state-of-the-art large vocabulary speech
recognition system.

The latter two packages will likely need to be updated to newer
upstream versions which are compatible with sphinxbase. This will involve
discarding or updating a few of the patches used to build the packages. I
updated sphinxbase to 5prealpha last August.

Here are the outstanding bug reports related to these:
