hghave: fix the definition of `python3` to work on Windows...

hghave: fix the definition of `python3` to work on Windows Both py2 and py3 executables are named `python.exe`, and may or may not be on PATH. So use the dispatcher executable that comes with py3 to fetch the version of the latest py3 executable. This allows at least one relnotes test to run on Windows.

fuzz: add a quick README to try and document how to test new fuzzers...

      How to add fuzzers (partially cribbed from oss-fuzz[0]):

        1) git clone https://github.com/google/oss-fuzz

        2) cd oss-fuzz

        3) python infra/helper.py build_image mercurial

        4) docker run --cap-add=SYS_PTRACE -it -v $HG_REPO_PATH:/hg-new \

               gcr.io/oss-fuzz/mercurial bash

        5) cd /src

        6) rm -r mercurial

        7) ln -s /hg-new mercurial

        8) cd mercurial

        9) compile

fuzz: add some more docs about building/running fuzzers...

              r36716
            
        10) ls $OUT

      Step 9 is literally running the command "compile", which is part of

      the docker container. Once you have that working, you can build the

      fuzzers like this (in the oss-fuzz repo):

      python infra/helper.py build_fuzzers --sanitizer address mercurial $HG_REPO_PATH

      (you can also say "memory", "undefined" or "coverage" for

      sanitizer). Then run the built fuzzers like this:

      python infra/helper.py run_fuzzer mercurial -- $FUZZER
