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.

virt plugin: Replace virTypedParamsFree() with virTypedParamsClear() and sfree().
The parameters are allocated with calloc(), freeing them with a library
function is unintuitive at best. Also, the library functions appears to
be missing the appropriate function attribute to tell clang / GCC that
it will free the pointer, resulting in a false-positive scan-build
report.

perl plugin: Fix potential double-free.
The av2notification_meta() function updated it's parameter by doing
(*m) = malloc();
Afterwards, if an error occurred, it would call `free(*m);` and (potentially)
return, leaving an invalid pointer stored in `m`. The caller would then try to
free the returned pointer because it was non-NULL.
This patch fixes this by doing several code cleanups:
* The meta argument is not updated unnecessarily. Instead, a local variable
is allocated and used within the loop and only on success is the return
pointer updated.
* Introduce additional local variables instead of re-using the `tmp` variable
multiple times.
* Name the variable pointing to the end of the linked list appropriately
`tail` and remove one level of indirection. Reading code that is using
pointers to pointers is unnecessarily hard.

src/utils_cmd_putval.c: Fix multi-value PUTVAL.
vl.values was allocated outside of the loop and then copied into each

bind plugin: Use timegm() to convert to time_t if available.
FreeBSD doesn't provide the "extern long timezone", presumably because
it's "only" an XSI extension, leading to a portability issue with the
previous approach.
timegm() is a non-standard function available in GNU's and BSD's libc
which is doing exactly what we need. The previous code is left as a
fallback.
Remove utils_ignorelist.[ch] from daemon; link plugins directly.
The collectd daemon isn't using the "ignorelist" functionality itself --
it was only linked in to provide it to loaded plugins. Since the code is
under the GPL, this interfers with our intend of having an MIT licensed
daemon.
This patch changes the build system to link plugins with the ignorelist
directly instead of expecting the symbols to be in the daemon.
