9f3cbd580e Fix multi master bugs: 1. we fail to create the temp file. 2. We use a master RDB as our backup even though we merged databases (and therefore it is not representitive)

1aa5638b93 RDB: make sure to abort on LZF encoding error.

3e75e77dcd 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.

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
