Redis Outplug Plugin using hiredis library

tested in Centos 6.2 and Archlinux

BUILDING THIS PLUGIN
Requires the hiredis C client library: https://github.com/redis/hiredis/

in your /etc/rsyslog.conf, together with other modules:

Brian Knox <briank@talksum.com>

---------------------------------------------------------------------------------------------
module(load="omhiredis")

template(name="simple_count" type="string" string="HINCRBY progcount %programname% 1")

action(name="simple_count_redis" type="omhiredis" queue.type="FixedArray" queue.size="10000" queue.dequeuebatchsize="100" template="simple_count")
---------------------------------------------------------------------------------------------

Note: dequeuebatchsize now sets the pipeline size for hiredis, allowing pipelining commands.
Note: this plugin will NOT handle full rsyslog messages properly yet. spaces in a property will
        cause the redis command to be constructed improperly.  a fix for this is in the works!
