backout: provide linear backout as a default (without --merge option)

This changes backouts changeset to retain linear history, .e. it is committed
as a child of the working directory parent, not the reverted changeset
parent.

The default behavior was previously to just commit a reverted change as a
child of the backed out changeset - thus creating a new head. Most of
the time, you would use the --merge option, as it does not make sense to
keep this dangling head as is.
The previous behavior could be obtained by using 'hg update --clean .' after a
'hg backout --merge'.

The --merge option itself is not affected by this change. There is also
still an autocommit of the backout if a merge is not needed, i.e. in case
the backout is the parent of the working directory.

Previously we had (pwd = parent of the working directory):
                  pwd     older
backout           auto    merge
backout --merge   auto    commit

With the new linear approach:
                  pwd     older
backout           auto    commit
backout --merge   auto    commit

auto: commit done by the backout command
merge: backout also already committed but explicit merge and commit needed
commit: user need to commit the update/merge

  $ cp "$TESTDIR"/printenv.py .

  > if sys.argv[1] != "user@dummy":
  >     sys.exit(-1)

  > if not os.path.exists("dummyssh"):
  >     sys.exit(-1)
  > 
  > os.environ["SSH_CLIENT"] = "127.0.0.1 1 2"
  > 
  > log = open("dummylog", "ab")
  > log.write("Got arguments")
  > for i, arg in enumerate(sys.argv[1:]):
  >     log.write(" %d:%s" % (i+1, arg))
  > log.write("\n")
  > log.close()
  > r = os.system(sys.argv[2])
  > sys.exit(bool(r))
  > EOF
