logging: remove unused message-id scripts

The current unused implementation for message-ids in the logs depends on
automatically generated files. The generated files are not included in
the distributed tarball. This causes issues when distributions build
packages, they need to re-run ./autogen.sh to create the needed files.

I thought of including the generated files in the distribution tarball.
However, the contents of these files are not actively used, so it seems
to make more sense to drop it all together. These functions were the
only users of libintl and gettext too, so dropped the requirement
checking from configure.ac.

A replacement for the message-id logging framework is in progress. Any
changes that this patch makes, can be reverted in the submission of
patches for the new framework.
