Fix some things I noticed while reviewing v1, and follow Rich's idea to add a new nbdkit_set_error() utility function with a binding for Python users to request a particular error (rather than being forced to live with whatever stale value is in errno after all the intermediate binding glue code). I could not easily find out how to register a C function callable from perl bindings, and have

This patch proposes to drop support for Python 2 in nbdkit. Rather than abruptly drop it everywhere, my proposal is that we point people to nbdkit 1.14 (the current stable version) if they want to continue with Python 2 plugins, while gently reminding them of the upcoming Python 2.7 end of life announcement. Libnbd never supported Python 2. Libguestfs in theory supports Python 2 but I dropped

This cleans up the existing code base with regards to implicit use of errno from language bindings, then rebases the previous work in python on top of that. I'm still playing with the perl bindings, but got further after reading 'perldoc perlembed'.
