run-tests: test result shows when a failed test could not start a server

Failing to start a server happens regularly, at least on windows buildbot.
Such a failure often has nothing to do with the test, but with the environment.
But half the test output can change because some data is missing. Therefore this
is worth an extended error message.

Detect the server failure in the diff output because it is most reliable
there. Checking the output only does not show if the server failure was
expected.

 Old failure message when server start failed:
Failed test-serve.t: output changed

 New message:
Failed test-serve.t: serve failed and output changed

  $ hg init
  $ echo This is file a1 > a
  $ echo This is file b1 > b
  $ hg add a b
  $ hg commit -m "commit #0"
  $ echo This is file b22 > b
  $ hg commit -m "comment #1"
  $ hg update 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ rm b
  $ hg commit -A -m "comment #2"
  removing b
  created new head
  $ hg update 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg update
  abort: not a linear update
  (merge or update --check to force update)
  [255]
  $ rm b
  $ hg update -c
  abort: uncommitted changes
  [255]
  $ hg revert b
  $ hg update -c
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mv a c

In theory, we shouldn't need the "-y" below, but it prevents this test
from hanging when "hg update" erroneously prompts the user for "keep
or delete".

Should abort:

  $ hg update -y 1
  abort: uncommitted changes
  (commit or update --clean to discard changes)
  [255]
  $ mv c a

Should succeed:

  $ hg update -y 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
