To prevent build failures when a large patch series is committed, like
happened in https://ci.appveyor.com/project/jrfonseca-fdo/mesa/build/322
due to 10 commits between dac2964f3e and
6f428328d3 where submitted before the
build slave started the git clone.
100 commits should be bigger than any patch series seen in practice, and
it takes practically the same time to download as 5 commits.

Unforunately the Appveyor -> SourceForge connection seems a bit
unreliable, causing frequent build failures while downloading
winflexbison (approx once every 2 days).
Fetching winflexbison archive into Appveyor's cache should eliminate
these.
Fetching Python modules from PyPI doesn't seem to be a problem, so they
are left alone for now, though they could eventually get the same
treatment.
AppVeyor doesn't require an appveyor.yml in the repos (in fact it has
some limitations as noted in comments below), but doing so has two great
advantages over the web UI:
- appveyor.yml can be revisioned together with the code, so instructions
should always be in synch with the code
- appveyor.yml can be reused for people's private repositories (be on
fdo or GitHub, etc.)
