This is a tracker ticket for a number of changes which simplify the code and allow us to use new language features.

We will no longer support Python versions older than 2.6, and GTK older than 2.18, clients older than v0.12.6:

• exception handling: r7445, r7444

• assume capabilities are present (xpra v0.7.x or newer): r7315, r7314, r7313
• added python version guard: r7310
• packaging cleanups: r7311
• remove old libav fork dec_avcodec: r7378, r7312, r7308, r7400
• py3k compatible octal syntax: r7380
• removed support for GTK older than 2.18: r7382, r7383, r7394
• removed python 2.4 workarounds: r7425, r7426, r7427, r7428, r7380,
• use python 2.6 with lock context construct: r7435
• remove ImmutableSet: r7436
• use any(..): r7305
• assume the uuid module is present: r7437
• remove maxdeque and use deque(maxlen=N) directly: r7438
• assume fchmod is present: r7439
• struct improvements: r7440
• assume bytearray is present: r7441
• use with open(..) context manager for accessing files: r7451
• misc: r7450, r7449
• Py_ssize_t is always defined for us already: r7454
• require generic_window_types and raw_window_icons: r7468
• drop compat with versions older than 0.12.6: r7468, r7469, r7470
• make some cython modules mandatory: cyxor (r7480 + r7481), argb (r7482), cymaths (r7483)

This is enough for now, Python 2.6 is here to stay as it is used in centos 6.x.

Don't really see anything to test here. Just for the sake of thoroughness though, will comment as looked at.
