wireproto: don't compress errors from getbundle()

Errors should be small. There's no real need to compress them.
Truth be told, there's no good reason to not compress them either.
But leaving them uncompressed makes it easier to test failures
by looking at the raw HTTP response. This makes it easier for us
to write tests. It may make it easier for people writing their
own clients.

Initialize repository
the status call is to check for issue5130

  $ hg init server

  ...     with open(str(i), 'wb') as fh:

Streaming of secrets can be overridden by server config

  $ cd server
  $ hg serve --config server.uncompressedallowsecret=true -p $HGPORT -d --pid-file=hg.pid
  $ cat hg.pid > $DAEMON_PIDS
  $ cd ..

#if stream-legacy

Clone not allowed when full bundles disabled and can't serve secrets

  $ cd server
  $ hg serve --config server.disablefullbundle=true -p $HGPORT -d --pid-file=hg.pid
  $ cat hg.pid > $DAEMON_PIDS
  $ cd ..

  $ hg clone --stream http://localhost:$HGPORT secret-full-disabled

Local stream clone with secrets involved
(This is just a test over behavior: if you have access to the repo's files,
there is no security so it isn't important to prevent a clone here.)

  $ hg clone -U --stream server local-secret

Stream clone while repo is changing:

  $ mkdir changing
  $ cd changing

extension for delaying the server process so we reliably can modify the repo
while cloning

  $ cat > delayer.py <<EOF
  > import time
  > from mercurial import extensions, vfs
  > def __call__(orig, self, path, *args, **kwargs):
  >     if path == 'data/f1.i':
  >         time.sleep(2)
  >     return orig(self, path, *args, **kwargs)
  > extensions.wrapfunction(vfs.vfs, '__call__', __call__)
  > EOF

prepare repo with small and big file to cover both code paths in emitrevlogdata

  $ hg init repo
  $ touch repo/f1
  $ $TESTDIR/seq.py 50000 > repo/f2
  $ hg -R repo ci -Aqm "0"
  $ hg serve -R repo -p $HGPORT1 -d --pid-file=hg.pid --config extensions.delayer=delayer.py
  $ cat hg.pid >> $DAEMON_PIDS

clone while modifying the repo between stating file with write lock and
actually serving file content

  $ hg clone -q --stream -U http://localhost:$HGPORT1 clone &
  $ sleep 1
  $ echo >> repo/f1
  $ echo >> repo/f2
  $ hg -R repo ci -m "1"
  $ wait
  $ hg -R clone id
  000000000000
  $ cd ..

Stream repository with bookmarks
--------------------------------

(revert introduction of secret changeset)

  $ hg -R server phase --draft 'secret()'

add a bookmark

  $ hg -R server bookmark -r tip some-bookmark

clone it

#if stream-legacy
  $ hg clone --stream http://localhost:$HGPORT with-bookmarks
