Auto merge of #2393 - nathan-at-least:2391.make-release-script, r=nathan-at-least
make-release.py script
ref #2391
This is a new `make-release.py` script which automates creation of the 'release PR' branch.
It has partial unittest coverage (large around version parsing/sorting/serializing) and always runs unittests prior to doing actual work. Most of the testing was done manually by using the ``--repo`` arg on a test repo, then reseting its state each time I needed a new test (to get around git checks). There is no other 'dry run' functionality.

torcontrol: Handle escapes in Tor QuotedStrings
https://trac.torproject.org/projects/tor/ticket/14999 is tracking an encoding
bug with the Tor control protocol, where many of the QuotedString instances that
Tor outputs are in fact CStrings, but it is not documented which ones are which.
https://spec.torproject.org/control-spec section 2.1.1 provides a future-proofed
rule for handing QuotedStrings, which this commit implements.

Fix proton build issue with debian jessie, as used on CI servers.
Debian 8 stable ships with gcc 4.9.2 and cmake 3.0.2. Previously
the depends package used CMAKE_CXX_STANDARD to tell cmake to use
C++11, but the option requires cmakes 3.1+. To resolve the issue
we now update relevant CMakeLists.txt and set CMAKE_CXX_FLAGS.
