Merge lp:~bregma/geis/lp-1169249 into lp:geis

[Stephen M. Webb]

Prevent garbage collector from reclaiming filters passed to subscriptions in the Python bindings (lp: #1169249).

Fixes some Python3-Unicode-ctypes and Python-GC-ctypes interaction problems that was causing invalid data to be passed into the C library from the Python code.

Since there is no test suite infrastructure for the Python bindings, the only available test is to start the geisview tool with GEIS_DEBUG=3 set on the command line and observe the correct windowid being used, and that the geisview tool once again produces gesture data.

Nice. Looks good, and +1 for moving over to utf-8.
