evolve: refactor the code which swap two nodes (in divergence resolution)
I see that we are using the code to swap the "divergent" and "other" node;
and updating the evolvestate accordingly at many places in divergence
resolution. This patch extract that code to a function.
Although I don't have strong opinion on this patch. It's a volunteered
patch to remove some redundancy.

if len(sys.argv) < 2:
execname = os.path.basename(sys.argv[0])
print >> sys.stderr, "usage: %s CLIENT_ID" % execname
client_id = sys.argv[1]
subprocess.check_call(['hg', 'branch', "--force", "hammer-branch-%s" % client_id])
while True:
subprocess.check_call([
'hg', 'commit',
"--config", "ui.allowemptycommit=yes",
"--message", "hammer-%s" % client_id,
])
nodeid = subprocess.check_output([
'hg', 'log', '--rev', '.', '--template', '{node}'
])
subprocess.check_call([
'hg', 'debugobsolete', ''.join(reversed(nodeid)), nodeid
])
subprocess.check_call(['hg', 'pull'])
subprocess.check_call(['hg', 'push', '--force'])
