nut plugin: Multi-threaded ups polling with connect timeout.
Changes:
* Implemented use of 'plugin_register_complex_read', so querying will be multi-threaded;
* Added 'ConnectTimeout' option, implemented with use of 'upscli_tryconnect()' added in nut-2.6.2;
* The `upscli_cleanup()` should be called only at Collectd shutdown, excessive calls was removed;
* Added `upscli_init()` call if `ForceSSL` enabled.
* Added a check for duplicated values in `UPS` option.

apcups: allow to use plugin without explicit configuration
Previously the apcups plugin could not be used without defining
an explicit configuration.
While the apcups plugin did provide a localhost fallback, it
did not however provide a 3551 port fallback in practice,
eventhough a constant for that purpose was already present.

- Do not return error in configuration callback, which will cause
collectd to be stopped. Instead, report error in init callback, which
will unload incorrectly configured plugin.
- Remove redundant ProcessType configuration option, which was always set to
"secondary"
- Use functions from cf_util_get family for parsing config file
- In case of parsing errors perform plugin cleanup
- Correctly remove previously created shared memory object if user specified
"SharedMemObj" option with different value than default
- Prevent segmentation fault in dpdk_shm_cleanup
- Change 'send_updated' and 'notify' variable types to _Bool
This patch removes impact of keep_alive init failure on
link_status processing. Also changed default behaviour in configless
mode, where no <Plugin/> stanza is defined. Now both keep_alive
and link_status are enabled by default. On the other hand if
<Plugin/> stanza is present, both features are disabled by default
and user is responsible for specifying which one is active or not.

Current implementation attempts to open KA SHM only once during init callback.
If at the time primary DPDK application is not running shm_open will fail, which
will result in dpdkevents plugin being unloaded. Move KA SHM open logic to read
callback to allow plugin to attach to primary DPDK application later without a
need to restart collectd. Moreover, it will allow to determine if primary DPDK
application was killed and plugin should stop dispatching KA statistics.
Additionally modify dpdk_event_keep_alive_shm_open function to detect restart of
primary DPDK application. When primary DPDK application (with KA support) is
restarted it unlinks existing shared memory object and creates a new one. It's
necessary for the plugin to create a new SHM mapping in order to prevent reading
statistics from stale SHM block.

curl plugins: Use configured URL for all poll cycles
After redirect received, Collectd send subsequent requests to new location.
That is wrong - Collectd should use configured URL for all poll cycles, regardless of the responses received previously.
Problem was caused by libcurl issue 1631. To avoid that we set request url in each poll cycle.

curl_json plugin: Refactor the way trees/keys are stored.
Previously, keys had a "magic" as their first member which was used to
differentiate between the two types when they were returned from the
binary search tree.
This patch creates a new struct, cj_tree_entry_t, which includes an enum
identifying which union member is valid.

curl_json plugin: Fix array index and key handling.
Previously, the "key" was loaded by calling cj_cb_map_key() from
cj_cb_inc_array_index(). That means that the key for the previous element
was loaded as the array index was updated for the next element, resulting
in an off-by-one error. Also the key was not unset in time, resulting in
two metrics with the same identifier being created.
This patch fixes this with the following changes:
* cj_advance_array() (nee cj_cb_inc_array_index()) now loads the key for
the new index position instead of the previous one.
* The initial "0" key is loaded from cj_cb_start_array().
* cj_advance_array() always updates the key. The "update_key" argument
has been removed.
* Refactoring: key loading has been moved out of cj_cb_map_key() and
into its own function, cj_load_key().
Unit tests are in a separate commit for easier cherry-picking.
