dispatch: fix silly blackbox entries when hg is interrupted

When hg is interrupted, it creates ui.log like this:

1970/01/01 00:00:00 user @0000000000000000000000000000000000000000 (62488)> killed!
 exited 255 after 1.78 seconds

This is due to a scoping problem: two different uses of the name "msg"
collide. So rename one of them.

Check sidedata exchange with on-the-fly generation and removal
==============================================================

(Push) Target has strict superset of the source
-----------------------------------------------

  $ hg init source-repo --config experimental.revlogv2=enable-unstable-format-and-corrupt-my-data
  $ hg init target-repo --config experimental.revlogv2=enable-unstable-format-and-corrupt-my-data
  $ cat << EOF >> target-repo/.hg/hgrc
  > [extensions]
  > testsidedata=$TESTDIR/testlib/ext-sidedata.py
  > EOF
  $ cd source-repo
  $ echo aaa > a
  $ hg add a
  $ hg commit -m a
  $ echo aaa > b
  $ hg add b
  $ hg commit -m b
  $ echo xxx >> a
  $ hg commit -m aa

No sidedata is generated in the source
  $ hg debugsidedata -c 0

Check that sidedata capabilities are advertised
  $ hg debugcapabilities ../target-repo | grep sidedata
    exp-wanted-sidedata=1,2

We expect the client to abort the push since it's not capable of generating
what the server is asking
  $ hg push -r . ../target-repo
  pushing to ../target-repo
  abort: cannot push: required sidedata category not supported by this client: '1'
  [255]

Add the required capabilities
  $ cat << EOF >> .hg/hgrc
  > [extensions]
  > testsidedata2=$TESTDIR/testlib/ext-sidedata-2.py
  > EOF

We expect the target to have sidedata that was generated by the source on push
  $ hg push -r . ../target-repo
  pushing to ../target-repo
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 3 changesets with 3 changes to 2 files
  $ cd ../target-repo

  $ hg debugsidedata a 1

   entry-0002 size 32
  $ cd ..

(Push) Difference is not subset/superset
----------------------------------------

Source has one in common, one missing and one more sidedata category with the
target.

  $ rm -rf source-repo target-repo
  $ hg init source-repo --config experimental.revlogv2=enable-unstable-format-and-corrupt-my-data
  $ cat << EOF >> source-repo/.hg/hgrc
  > [extensions]

  > EOF
  $ hg init target-repo --config experimental.revlogv2=enable-unstable-format-and-corrupt-my-data
  $ cat << EOF >> target-repo/.hg/hgrc

  > EOF
  $ cd source-repo
  $ echo aaa > a
  $ hg add a
  $ hg commit -m a
  $ echo aaa > b
  $ hg add b
  $ hg commit -m b
  $ echo xxx >> a
  $ hg commit -m aa

Check that sidedata capabilities are advertised
  $ hg debugcapabilities . | grep sidedata
    exp-wanted-sidedata=1,2
  $ hg debugcapabilities ../target-repo | grep sidedata
    exp-wanted-sidedata=2,3

Sidedata is generated in the source, but only the right categories (entry-0001 and entry-0002)
  $ hg debugsidedata -c 0
  2 sidedata entries
   entry-0001 size 4
   entry-0002 size 32
  $ hg debugsidedata -c 1 -v
  2 sidedata entries
   entry-0001 size 4
    '\x00\x00\x006'
   entry-0002 size 32
    '\x98\t\xf9\xc4v\xf0\xc5P\x90\xf7wRf\xe8\xe27e\xfc\xc1\x93\xa4\x96\xd0\x1d\x97\xaaG\x1d\xd7t\xfa\xde'
  $ hg debugsidedata -m 2
  2 sidedata entries
   entry-0001 size 4
   entry-0002 size 32
  $ hg debugsidedata a 1
  2 sidedata entries
   entry-0001 size 4
   entry-0002 size 32


We expect the target to have sidedata that was generated by the source on push,
and also removed the sidedata categories that are not supported by the target.
Namely, we expect entry-0002 (only exchanged) and entry-0003 (generated),
but not entry-0001.
