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

redhat initscript: add timeout when stopping the daemon
This mitigates the risk of having 2 daemons running simultaneously
during a short period, on restart.
The debian package's initscript does the same thing, using the same
timeout value.

curl_json: fix the array access implemented in f1e1e37e
In the avl-tree we store two different structs, cj_key_t for the value
we search, c_avl_tree_t for sub-nodes.
The old version does assume when it will find a key, and when a tree,
which doesn't have to be right in all cases.
Therefore we utilize the magic to revalidate this cast.
Being able to tell tree from key, we now can also implement array access
on the right most node of the tree-path.
