This fix is a refinement of a previous fix to avoid a possible AV if the buffer
to write to disk ends exactly at the last byte of a memory page.

Fix other typos.

The NETWORK SERVICE account was set using the localized string name, that

Fixes issue #455. Credits to @id-ilych for investigating the issue.

Fixes issue #454. Credits to @fangguanya for the fix.

Other doc fixes. (credit to @ammills01 and @InPermutation)

Fixed a few small grammatical errors. Specifically, the word 'in' was used twice

Credit to @DavidADoran for reporting the problem https://github.com/MSOpenTech/redis/issues/376 and providing
the code to reproduce the bug.

Add notice to install VS2013 Update 5 to make sure it compiles properly.

redis heap before freeing it.
Changed dictRehash to NOOP when called by the forked process to avoid
extra processing that is not required when the forked process is
saving the dataset.

Replication (including diskless replication) requires persistence to be
available. This fix prevents a crash and returns "ERR unknown command" to
the slave.
