py3: convert print to a function call in a few tests
I *think* this is the last of them.
py3: byteify windows.shelltocmdexe()
This makes test-doctest.py happy on Windows.
run-tests: flush output stream before prompting to accept changes
With py3 on Windows, the prompt to accept changes in an --interactive run wasn't
showing up until after the choice was read from stdin.
py3: use util.forcebytestr() to convert error messages to bytes
This makes the python 3 buildbot green again.

context: stop catching TypeError when converting hex nodeid to binary
It has been a programming error to pass a 40-character string that is
not a hex nodeid since
8b86acc7aa64 (context: drop support for looking
up context by ambiguous changeid (API), 2018-04-28), so we can just
let it raise a TypeError.

context: stop catching and re-raising FilteredRepoLookupError
FilteredRepoLookupError is only raised by changectx's constructor and
the higher-level scmutil.revsymbol(), so there's no need to catch it
in changectx's constructor.
