2de544cfcc 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

ba809f26d4 make replication tests more stable on slow machines
solving few replication related tests race conditions which fail on slow machines

bugfix in slave buffers test: since the test is executed twice, each time with
a different commands count, the threshold for the delta can't be a constant.

3f068b92b9 Test: fix, hopefully, false PSYNC failure like in issue #2715.
And many other related Github issues... all reporting the same problem.
There was probably just not enough backlog in certain unlucky runs.
I'll ask people that can reporduce if they see now this as fixed as
well.

2b36706a48 Test: replication-psync, wait more to detect write load.
Slow systems like the original Raspberry PI need more time
than 5 seconds to start the script and detect writes.
After fixing the Raspberry PI can pass the unit without issues.

Added for debugging and forgot there.

e7887e6060 Test: hopefully more robust PSYNC test.
This is supposed to fix issue #1417, but we'll know if this is enough
only after a couple of runs of the CI test without false positives.

16f2c3ea14 Test: check that replication partial sync works if we break the link.
The test checks both successful syncs and unsuccessful ones by changing
the backlog size.
