bundle2: don't try to recover from a GeneratorExit (issue4785)

GeneratorExit means the other end of the conversation has already
stopped listening, so don't try and yield out error
information. Instead, just let the GeneratorExit propagate normally.

This should resolve esoteric issues observed with servers that have
aggressive timeouts waiting for data to send to clients logging
internal Python errors[0]. This has been observed with both gunicorn's
gevent worker model and with scm-manager's built-in webserver (which
itself is something sitting inside jetty.)

Revert interactive tests
1 add and commit file f
2 add commit file folder1/g
3 add and commit file folder2/h
4 add and commit file folder1/i
5 commit change to file f
6 commit changes to files folder1/g folder2/h
7 commit changes to files folder1/g folder2/h
8 revert interactive to commit id 2 (line 3 above), check that folder1/i is removed and
9 make workdir match 7
10 run the same test than 8 from within folder1 and check same expectations

Check editing files newly added by a revert

1) Create a dummy editor changing 1 to 42
  $ cat > $TESTTMP/editor.sh << '__EOF__'
  > cat "$1"  | sed "s/1/42/g"  > tt
  > mv tt  "$1"
  > __EOF__

2) Add k
  $ printf "1\n" > k
  $ hg add k
  $ hg commit -m "add k"

3) Use interactive revert with editing (replacing +1 with +42):
  $ printf "0\n2\n" > k
  $ HGEDITOR="\"sh\" \"${TESTTMP}/editor.sh\"" hg revert -i  <<EOF
  > y
  > e
