Cherry pick 560ec60e

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.

Improved getting pid

See https://sourceware.org/glibc/wiki/Release/2.20#Packaging_Changes

```sh
$ ~ pidof redis-server
# nothing

$ ~ ps aux | grep [r]edis
redis      593  0.0  0.0  36900  5564 ?        Ssl  Dec02   1:37 /usr/bin/redis-server 127.0.0.1:6379
klay     15927  0.0  0.0  16772  6068 pts/6    S+   13:58   0:00 redis-cli

$ ~ uname -a
Linux edge 3.17.4-1-ARCH #1 SMP PREEMPT Fri Nov 21 21:14:42 CET 2014 x86_64 GNU/Linux
```

This allows shell pipes to correctly end redis-cli.

Ref #2066

Thanks to @badboy for the help in checking the build after the fix.

Addressing https://github.com/MSOpenTech/redis/issues/188

- Made gettimeofday use GetSystemTimePreciseAsFileTime when available
- Introduced definitions for gettimeofday_fast and gettimeofday_precise,
  so that calls can be specialized based on specific usage requirements
- Introduced GetHighResRelativeTime, for high-resolution relative time
  measurements on all Windows versions.

Slave processes were not using the master process log file.
On Unix this is relying on the server.logfile variable being available
to the slave processes through fork(), and reopening the logfile
in the slaves (on every log event).
On Windows we don't use server.logfile and require an explicity call
to setLogFile.
I resorted to explicitly passing the logfile to the slaves as a
command line argument, so the logfile argument (and logging) can be
available to the slave before qfork and globals setup have completed.

Writing to the same file atomically from multiple processes requires
using CreateFile with FILE_APPEND_DATA, instead of fopen, which provides
atomicity on Unix but not on Windows.

Also changed the implementation to not reopen the logfile on every
log event, and not flushing the file on every write. Performance is
dramaticaly improved this way.

Track bandwidth used by clients and replication (but diskless
replication is not tracked since the actual transfer happens in the
child process).

This includes a refactoring that makes tracking new instantaneous
metrics simpler.
