da82723858 Handle wait3() errors.
My guess was that wait3() with WNOHANG could never return -1 and an
error. However issue #2897 may possibly indicate that this could happen
under non clear conditions. While we try to understand this better,
better to handle a return value of -1 explicitly, otherwise in the
case a BGREWRITE is in progress but wait3() returns -1, the effect is to
match the first branch of the if/else block since server.rdb_child_pid
is -1, and call backgroundSaveDoneHandler() without a good reason, that
will, in turn, crash the Redis server with an assertion.

7cfdccd94e Remove "s" flag for MIGRATE in command table.
Maybe there are legitimate use cases for MIGRATE inside Lua scripts, at
least for now. When the command will be executed in an asynchronous
fashion (planned) it is possible we'll no longer be able to permit it
from within Lua scripts.

0cb66fa156 Fix MIGRATE entry in command table.
Thanks to Oran Agra (@oranagra) for reporting. Key extraction would not
work otherwise and it does not make sense to take wrong data in the
command table.

ff6d296000 Scripting: ability to turn on Lua commands style replication globally.
Currently this feature is only accessible via DEBUG for testing, since
otherwise depending on the instance configuration a given script works
or is broken, which is against the Redis philosophy.

2dabf82d5f Fix call() FORCE_REPL/AOF flags setting.
This commit also inverts two stanzas of the code just becuase they are
more logical like that, not because currently it makes any difference.

fc38235664 Scripting: single commands replication mode implemented.
By calling redis.replicate_commands(), the scripting engine of Redis
switches to commands replication instead of replicating whole scripts.
This is useful when the script execution is costly but only results in a
few writes performed to the dataset.

Morover, in this mode, it is possible to call functions with side
effects freely, since the script execution does not need to be
deterministic: anyway we'll capture the outcome from the point of view
of changes to the dataset.

In this mode math.random() returns different sequences at every call.

If redis.replicate_commnads() is not called before any other write, the
command returns false and sticks to whole scripts replication instead.

73427462ed Server: restartServer() API.
This new function is able to restart the server "in place". The current
Redis process executes the same executable it was executed with, using
the same arguments and configuration file.
