(cherry picked from commit c6558e09)

To make throttling by label fully active, the "throttle" option
has to be specified with a specific label.

You can now specify "skip_gate" in the Gerrit comments when you
do a +2 code review to tell Jenkins not to actually run the
gate.  You'd do this if you plan to manually merge the change.

Also updated the "printenv" debug output to better sort multi-line
comments.

Originally, the eligible nodes for a job were labelled only by
"swdev-docker".  So basically any node could run any job.  We had
found that allowing a node to run more than 1 gate at a time was
problematic so we limited the nodes to processing 1 job at a time.
With the creation of the Asterisk 17 branches however, we now have
so many active branches that getting checks and gates through in
a timely manner is problematic when a node can run only 1 job
at a time.

Now the nodes are also labelled by the job type they can run.
For instance: "asterisk-check", "asterisk-gate", etc.  With the
"Throttle Concurrent Builds" plugin, we can now allow a node to
run more than 1 job BUT throttle by job type.  For instance:
  Allow 2 jobs but only 1 asterisk-gate at a time.
Now a node can run 2 checks or 1 check and 1 gate or 1 gate but
not 2 gates at a time.

There were still a few places in the code that could overflow when "packing"
a json object with a value outside the base type integer's range. For instance:

unsigned int value = INT_MAX + 1
ast_json_pack("{s: i}", value);

would result in a negative number being "packed". In those situations this patch
alters those values to a ast_json_int_t, which widens the value up to a long or
long long.

You now select voicemail backends like normal dialplan applications, so
there is no longer a need for their own menuselect category.

The code for gathering contacts could result in the same contact
being retrieved and added to the list multiple times. The container
which stores the contacts to display will now only allow a contact
to be added to it once instead of multiple times.

When a module fails to register itself (usually a coding error
in the module), dlerror() can return NULL.  We weren't checking
for that in load_dlopen() before trying to strdup the error message
so a SEGV was thrown.  dlerror() is now surrounded with an S_OR
so we don't SEGV.

We don't support non-core modules for Certified releases but we
were enabling them for CI builds which was causing lots of test
failures.  Now we don't.

Details:
  - The memcpy() call copied part of "dahdi_conf" and not "dahdi_conf.mfcr2"
  - As a result, the memcmp() in dahdi_r2_get_link() always fails
  - This cause dahdi_r2_get_link() to create new link for every channel
    (instead of a new link for every ~30 channels)
  - With the fix, far less links are generated -- so we use far less threads

We're at the point where there are enough Jenkins jobs for
Asterisk branches than even cleaned checkouts of Asterisk
will add up to more disk space than is available on the
in-memory workspace mount.  Since we archive all relevent
artifacts anyway, there's no need to keep the workspace
around after the job finishes, whether it succeeds or fails.
