convert: improve exception reporting for SVN logstream

- catch all exceptions
- pickle a stringified version of the exception
- use a normal abort

Hopefully this will result in less mysterious convert exceptions

Create a repo with some stuff in it:

  $ hg init a
  $ cd a
  $ echo a > a
  $ echo a > d
  $ echo a > e
  $ hg ci -qAm0
  $ echo b > a
  $ hg ci -m1 -u bar
  $ hg mv a b
  $ hg ci -m2
  $ hg cp b c
  $ hg ci -m3 -u baz
  $ echo b > d
  $ echo f > e
  $ hg ci -m4
  $ hg up -q 3
  $ echo b > e
  $ hg branch -q stable
  $ hg ci -m5
  $ hg merge -q default --tool internal:local
  $ hg branch -q default
  $ hg ci -m6

Need to specify a rev:

  $ hg graft
  abort: no revisions specified
  [255]

Can't graft ancestor:

  $ hg graft 1 2
  skipping ancestor revision 1
  skipping ancestor revision 2
  [255]

Can't graft with dirty wd:

  $ hg up -q 0
  $ echo foo > a
  $ hg graft 1
  abort: outstanding uncommitted changes
  [255]
  $ hg revert a

Graft a rename:

  $ hg graft 2 -u foo
  grafting revision 2
  merging a and b to b
  $ hg export tip --git
  # HG changeset patch
  # User foo
  # Date 0 0
  # Node ID d2e44c99fd3f31c176ea4efb9eca9f6306c81756
  # Parent  68795b066622ca79a25816a662041d8f78f3cd9e
  2
  
  diff --git a/a b/b
  rename from a
  rename to b
  --- a/a
  +++ b/b
  @@ -1,1 +1,1 @@
  -a
  +b

Look for extra:source

  $ hg log --debug -r tip

  abort: unresolved conflicts, can't continue
  (use hg resolve and hg graft --continue)

Continue without resolve should fail:

Fix up:

  $ echo b > e
  $ hg resolve -m e

Continue with a revision should fail:

  $ hg graft -c 6
  abort: can't specify --continue and revisions
  [255]

Continue for real, clobber usernames

  $ hg graft -c -U
  grafting revision 4
  grafting revision 3

  $ hg diff -r 6
  $ hg status --rev 0:. -C
  M d
