Fix modbus segfault / New strategy for connecting
The previous implementation had a reconnection loop which should not
really be necessary. Idea tried here is to check if connection is alive,
and establish it if not. Change was begun because previously connection
would only be attempted as a retry, so on first pass a NULL was handed to
libmodbus which caused segmentation faults reproducibly.

csnmp_read_table: Change GETNEXT request behaviour (+ bugfix 235)
This patch changes the snmp GETNEXT request behaviour implemented in snmp.c.
The old implementation requested all OIDs using GETNEXT requests until all OIDs
left their own subtree. In cases were trees in a Data template are much longer
than other trees the shorter subtrees were re-requested over and over again.
The new implementation will only request OIDs that did not already leave their
subtrees (see the oid_todo_list implementation for details). This renders the
function csnmp_check_res_left_subtree useless as the oid_todo_list keeps track
if all OIDs have finished.
During tests against Cat6500 (CatOS/IOS) as well as Nexus5k (NX-OS) it looks as
though GETNEXT requests (when requesting multiple OIDs like all 14 dot3Stats
errors from Etherlike-MIB) can take about 5-10ms (CatOS 30ms) longer if they wrap
to the next OID.
This does not sound much but when collecting data for the Etherlike-MIB (that only
has entries for physical interfaces) with a collectd "Instance" variable in IF-MIB
(that has entries for all physical as well as pseudo [SVIs, VLANs, ...] interfaces)
this can make a notable difference (e.g. for core routers that have all SVIs and
VLANs but only some switches attached):
IOS-Core-Router ifName 550 entries
dot3StatsFCSErrors 70 entries
------------
480 entries * 10ms = 4.8s overhead
CatOS-Access-Sw. ifName 840 entries
dot3StatsFCSErrors 490 entries
------------
350 entries * 30ms = 10.5s overhead
After refactoring csnmp_read_table "Instance" and "Value" OIDs are now handled
consistently (so no pointer-forward foo needed). It doesn't change any logic
and data structures, though - so there should not be any impact to other
functions.
The refactored code also fixes GitHub bugs #235 and #258. This bug is due to
reusing the status variable in following code section which might lead to errors
if the subtrees are of different length:
1436 /* Calculate the current suffix. This is later used to check that the
1437 * suffix is increasing. This also checks if we left the subtree */
1438 status = csnmp_oid_suffix (&suffix, &vb_name, data->values + i);

postgresql plugin: Don't access realloc'ed memory.
D'oh! This is the most stupidest bug: all database connection objects are
stored in a plugin-global array and a pointer to each object was passed around
to the worker functions. This array used to be an array of objects (rather
than pointers) and was realloc'ed every time a new connection was added. Now,
the realloc caused the old pointer to not be valid any more, thus, any but the
last database connection were later accessing memory out of range. This caused
the plugin to segfault if more than one database connection was used.
Thanks to Greg Swift for reporting this!
