73a945c73c 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.

e70fbad802 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)

29754ebe22 diskless replication on slave side (don't store rdb to file), plus some other related fixes 
The implementation of the diskless replication was currently diskless only on the master side.
The slave side was still storing the received rdb file to the disk before loading it back in and parsing it.

This commit adds two modes to load rdb directly from socket:
1) when-empty
2) using "swapdb"
the third mode of using diskless slave by flushdb is risky and currently not included.

other changes:
--------------
distinguish between aof configuration and state so that we can re-enable aof only when sync eventually
succeeds (and not when exiting from readSyncBulkPayload after a failed attempt)
also a CONFIG GET and INFO during rdb loading would have lied

When loading rdb from the network, don't kill the server on short read (that can be a network error)

Fix rdb check when performed on preamble AOF

tests:
run replication tests for diskless slave too
make replication test a bit more aggressive
Add test for diskless load swapdb
