47e7652611 Active Replicas should always use their own slaveseldb variable when sending/saving rdbs - never those of their masters. This is because the Active Replica is also simultaneously a master

bd0f06c18c RDB: handle encoding errors with rdbExitReportCorruptRDB(). 
Without such change, the diskless replicas, when loading RDB files from
the socket will not abort when a broken RDB file gets loaded. This is
potentially unsafe, because right now Redis is not able to guarantee
that encoding errors are safe from the POV of memory corruptions (for
instance the LZF library may not be safe against untrusted data?) so
better to abort when the RDB file we are going to load is corrupted.

Instead I/O errors are still returned to the caller without aborting,
so that in case of short read the diskless replica can try again.

c56b4ddc6f prevent diskless replica from terminating on short read 
now that replica can read rdb directly from the socket, it should avoid exiting
on short read and instead try to re-sync.

this commit tries to have minimal effects on non-diskless rdb reading.
and includes a test that tries to trigger this scenario on various read cases.

56258c6b7d Module API for Forking 
* create module API for forking child processes.
* refactor duplicate code around creating and tracking forks by AOF and RDB.
* child processes listen to SIGUSR1 and dies exitFromChild in order to
  eliminate a valgrind warning of unhandled signal.
* note that BGSAVE error reply has changed.

valgrind error is:
  Process terminating with default action of signal 10 (SIGUSR1)
