getpeername() is returning invalid addresses on ipv6 sockets accepted
with AcceptEx, filling only 16 bytes of the address structure.
Providing a workaround by saving the remote address returned by
GetAcceptExSockaddrs, which is valid.

The debug version of isprint() raises an assert when the input value
is not EOF or in the range 0 through 0xFF, inclusive.
The trick is that the char value needs to be passed as unsigned,
before being converted to int.

It looks like https://github.com/MSOpenTech/redis/commit/62cc0e320d9afe28cc44a642d9e8f5e1c0e5d775#diff-07ce465381b20e496c6fb51bedd3491fR3105
inadvertently made the Windows side not abort when an OOM occurs.

During diskless replication the master forks a child, which on posix
simply inherits the socket file descriptors for the connections to
the slaves.
A unix pipe is also used for the child to report the results back
to the master.

The bulk of the porting work is in making sure that the socket
file descriptors and pipe file descriptor are propagated correctly
from the master to its child.

There is no apparent reason for the child to wait for the
startOperation event to be signaled.

Refactor BeginForkOperation in preparation for diskless replication:
- Separate copying of operation data and child process creation
- Provide specific entry points for each operation type

Bug fixes

Pipe mode was broken due to CRT's translation of CRLF sequences.

Commit 08e4226e broke redis-benchmark.

Made time function initialization automatic on first execution.
Added explicit initialization of time functions in redis-benchmark, to
avoid additional cost on first benchmark execution.

Adopting the suggestions at https://github.com/MSOpenTech/redis/issues/172
We no longer commit the binaries into the repo.
Instead, we create periodic releases on the release page.

Otherwise there are security risks, especially when providing Redis as a
service, the user may "sniff" for admin commands renamed to an
unguessable string via rename-command in redis.conf.

The old list did not made much sense... and the flag is currently not
used at all, so no side effects.

Adds a symlink for redis-sentinel when Make install

It fixes a bad bug that crashes the server in certain conditions
as shown in issue #2210.

Related to #2094.

People mostly use SORT against lists, but our prior
behavior was pretending lists were an unordered bag
requiring a forced-sort when no sort was requested.

We can just use the native list ordering to ensure
consistency across replicaion and scripting calls.

Closes #2079
Closes #545 (again)

status command currently reports success when redis has crashed and the pid file still exists. Changing to check the actual process is running.
