Previously, GETRANGE of a key containing nothing ("")
would allocate a large (size_t)-1 return value causing
crashes on 32bit builds when it tried to allocate the
4 GB return string.

32 bit builds don't have a big enough long to capture
the same range as a 64 bit build.  If we use "long long"
we get proper size limits everywhere.

Also updates size of unsigned comparison to fit new size of `end`.

Fixes #1981

We can save a little work by aborting when we enter the function
if we're disconnected.

Also related to #1929.

This closes issue #1929, the other part was fixed in the context of issue

This allows to support datasets with more than 2 billion of keys
(possible in very large memory instances, this bug was actually
reported).

Closes issue #1814.

Companion for 8eeb1802, but dealing with hiredis.

We don't want scripts doing CLIENT SETNAME
or CLIENT KILL or CLIENT LIST or CLIENT PAUSE.

Originally reported by Chris Wj then proper
action inspired by Itamar Haber.

This just deletes old code that didn't get removed when
logic changed.  We were setting offsets that never
got read anywhere.

Since clients are now just cloned, we don't need to track
per-client buffer offsets anywhere because they are all
the same from the original client.

Closes #1097

Clearly ip[32] is wrong, but it's less clear that buf[32] was wrong
without further reading.

Closes #1914

Once this is merged:
  - merge the latest changes to commands.json in antirez/redis-doc
  - re-run: utils/generate-command-help.rb > src/help.h

Then we'll have nice and easy tab-completed help in redis-cli again.

Closes #1909

Uses ANSI "default background" color code after closing tests
so any non-black terminals don't remain polluted.

Fixes #1649
Closes #1912

Sentinel needs to die with a more accurate error message
when attempted to open a config from STDIN.

See: https://groups.google.com/forum/#!topic/redis-db/sYx7VNMWaNM

It has an important name, but nothing uses it...

Closes #878

Also adds a fallthrough case for when given
large values (like overflow numbers of 2^64 by mistake).

Closes #858

Closes #857

Fix redis-cli prompt to state "not connected" after a SHUTDOWN command
is sent.

d is more clear because the type of argument is dict not dictht

Closes #513

The bug was found by @CAFxX, thanks!
See issue #1940.

This raises the max string to 4GB without any downside.

Hat tip to @rfuchs. See: https://github.com/redis/hiredis/pull/178.

Fixes #1187

Also moves acceptHandler() to be near the other accept...() functions.

Closes #1105

For some Solaris flavours, the inet_aton in in resolv library.
Not linking this library will introduce link error.

Improves compatability with older Solaris and still
works on new Solaris.

Closes #1092
