Use bytearray += instead of bytearray.extend

travis seems to be stuck building a missing commit, hopefully this frees it.

This compiles to fewer bytecodes and uses built-in slots instead of
method dispatch, so it should be faster.

Benchmarks show a tiny improvement (using the same benchmarks as
issue #1233, so not exactly designed to test this):

Use a buffer to generate HTTP chunks.

The intent is to reduce network overhead for small chunk sizes withoud adding much overhead for larger sizes.

Fixes #1233.

Only issue the ssl MonkeyPatchWarning if we can be pretty sure there will be problems

This increases the false negative chances, but decreases the false positives substantially.

* Switch off prospector, go back to plain pylint.

prospector wasn't working on CI for some reason.

Fix the outstanding pylint errors.

* Explicitly request pylint 2 on Python 3

* Also need to update astroid.

* pylint warning generated on Travis (case-sensitive filesystem.)

* Sleeping updates the loop's current time always.

That had been disabled for libuv, but now that we run timers in our own code that's not a concern anymore.

Fixes #1227.

* Try Python 3.5.5 because of the weird Illegal Instruction crash we suddenly see with 3.5.4

* Increase the value; test_sendall_timeout was often failing to actually timeout.

* Really python3.5

Allow weakreferences to Queue objects. Fixes #1217.

Fix gevent.os.nb_write/read not always closing the IO event the opened, which is a problem on libuv.

Also fix the formatting in changelog_1_0.rst so it renders legibly.
