ipmi: use SIGIO instead of SIGUSR2 to avoid conflict with JVM
Java uses SIGUSR2 to suspend/resume threads. The OpenIPMI plugins also
need a signal to resume its event loop when setting a timer. They can't
both use the same signal. We ask OpenIPMI to use SIGIO instead.
This should fix #114.

write_http: make callback names context-dependent
This allows multiple destinations to work again (fixes #821), using the
same logic as other write plugins.
The callback name would now be something like:
`write_http/http://example.com/endpoint`
which is not very nice.
The next step would be to change this plugin to use `<Node>` blocks
like many others, and pass the URL as a parameter inside each instance
block. So I see this patch as the minimum required to let 5.3 and 5.4
users use this plugin with multiple destinations.

collectdctl command hangs on AIX and returns error 0 on Solaris.
Summary:
Problem: collectdctl command hangs on AIX and returns error 0 on Solaris.
Root cause - client (collectdctl) and server (collectd daemon) are using fprintf to communicate using Unix domain socket, Since fprintf buffers, command sent by client did not reach server, since client does not get the response, it closes the socket which forces the client to flush the command, now server receives the command, when responding, it gets socket error because the client already closed the socket.
Solution: Added flush after all fprintf calls.
Test Plan: Tested collectdctl on AIX and SunOS for listval, getval commands

Equivalent patch to 79e90bba5, to avoid issue #804 introduced while

Let snmp_synch_response deal with PDU freeing
When reading from tables, upon errors the PDUs sent are already
freed by snmp_synch_response since they are right after
snmp_send is called.
This commit syncs collectd's approach with other occurences of
snmp_synch_response calls.
There might be a few corner cases where we leak PDUs, but it
is unclear how to check for those since we would need to
have an indication that snmp_send was never called, which
as far as I can tell is not possible.
The potential for failure in snmp_send is rather low and will
be easily spotted though, since when crafting invalid PDUs
snmp send will constantly fail and since valid configurations
can never leak memory.
This fixes #804

write_redis: re-add colon dropped in b7984797
When running f3706b0b87, the following command gets sent to redis:
"ZADD" "collectd/hostname/entropy/entropy" "1415487432.000000" "1415487432:932"
Meaning the value actually stored, and later returned by redis is:
"<timstamp>:<value>".
b7984797 accidentally dropped the comma separating the timestamp and the

never dispatched, remove the code entirely. We might want to add this back to
