This pull does the following in a bunch of commits:
scripted diff to use the bytes::hex() method in place of previous wrappers (b2x, bytes_to_hex_str, hexlify, …)
Update the build system (gitian and travis) to remove python2.7 and replace it with python3.5
Another scripted-diff to remove brackets after assert. This is unrelated to the python3.5 switch, but a stylistic commit, so probably not worth to split up. The motivation behind it is to avoid asserting on data structures (such as tuples of length one), which never fails:
0>>>assert(False,) # with brackets1>>>assertFalse, # without brackets2SyntaxError: invalid syntax
3>>>assertFalse# proper assertion4AssertionError
And then a final scripted diff to update the copyright headers in the test subfolder, since I touched most of the files anyway and it wouldn’t make sense to split this commit out into a separate pull.

@jnewbery You might be interested in reviewing this, since it removes some python2.7 leftovers from “Remove Python2 support” in #11881

Looks good. I especially like scripted-diff: test: Remove brackets after assert :100: Is there a flake warning we can add to enforce in that in future?
This is for inclusion in v0.19, so I’ll review after v0.18 is forked.

tACKfaa7cdf except PyEnv needs a full version number, i.e. 3.5.6. With that, I was able to run make check and the functional test suite on macOS 10.14.3, but I didn’t try the various linters and other tools.
