Add tests for fixing migrating slot at all stages:
1. when migration is half inited on "migrating" node
2. when migration is half inited on "importing" node
3. migration inited, but not finished
4. migration is half finished on "migrating" node
5. migration is half finished on "importing" node
Also add tests for many simultaneous slot migrations.

'processCommandAndResetClient' returns 1 if client is dead. It does it
by checking if serve.current_client is NULL. On script timeout, Redis will re-enter
'processCommandAndResetClient' and when finish we will set server.current_client
to NULL. This will cause later to falsely return 1 and think that the client that
sent the timed-out script is dead (Redis to stop reading from the client buffer).

In activeDefragSdsListAndDict when defrag list key sucess, the key
in dict is also replaced. Then the corresponding dictEntry is
defraged. But the dictEntry will be defraged in next step by defrag
the dict values too.

Add publish channel permissions check in processCommand.
processCommand didn't check publish channel permissions, so we can
queue a publish command in a transaction. But when exec the transaction,
it will fail with -NOPERM.
We also union keys/commands/channels permissions check togegher in
ACLCheckAllPerm. Remove pubsubCheckACLPermissionsOrReply in
publishCommand/subscribeCommand/psubscribeCommand. Always
check permissions in processCommand/execCommand/
luaRedisGenericCommand.
