Subject: [PATCH] liblouis: update to 3.1.0

Also, build Python 3 bindings.  The only thing that depends on
liblouis is Orca, and Orca needs these.
Build with --enable-ucs4.
To see a justification for why I did that,
have a look at https://bugs.archlinux.org/task/44319
Disable parallel builds; they fail for me.
Make sure .info files are installed.

+which has been merged upstream.
+The Python bindings use ctypes, and they load the .so as soon as they
+are imported.  setup.py imports them and calls the library's version()
+function, rather than hard-coding a version number.  This breaks crossbuilds.
