* shutdown each ctx independently
* fix completion of quiesce
* do not update shared ML charts
* Create ML charts on child hosts.
When a parent runs a ML for a child, the relevant-ML charts
should be created on the child host. These charts should use
the parent's hostname to differentiate multiple parents that might
run ML for a child.
The only exception to this rule is the training/prediction resource
usage charts. These are created on the localhost of the parent host,
because they provide information specific to said host.

A separate function call has been added to stop anomaly detection threads.
This commit removes the left over function calls that were made
internally when a host was being created/destroyed.

The number of dims per sample is always 1, ie. we are training and
predicting only individual dimensions.

* move global statistics workers to a separate thread; query statistics per query source; query statistics for ML, exporters, backfilling; reset replication point in time every 10 seconds, instead of every 1; fix compilation warnings; optimize the replication queries code; prevent long tail of replication requests (big sleeps); provide query statistics about replication ; optimize replication sender when most senders are full; optimize replication_request_get_first_available(); reset replication completion calculation;
* remove workers utilization from global statistics thread

* Remove calls to rrdset_next().
* Rm checks plugin
* Update documentantion
* Call rrdset_next from within rrdset_done
This wraps up the removal of rrdset_next from internal collectors, which
removes a lot of unecessary code and the need for if/else clauses in
every place.
The pluginsd parser is the only component that calls rrdset_next*()
functions because it's not strictly speaking a collector but more of a
collector manager/proxy.
With the current changes it's possible to simplify the API we expose
from RRD significantly, but this will be follow-up work in the future.
* Remove stale reference to checks.plugin
* Fix RRD unit test
rrdset_next is not meant to be called from these tests.
* Fix db engine unit test.
* Schedule rrdset_next when we have completed at least one collection.
* Mark chart creation clauses as unlikely.
* Add missing brace to fix FreeBSD plugin.

By default functions are declared as extern in C/C++ headers. The goal
of this PR is to reduce the wall of text that many headers have and,
more importantly, to make the declaration of extern'd variables - of
which we have many dispersed in various places - easily and quickly
identifiable.
Automatically generated with:
$ git grep -l '^extern.*(' '**.h' | \
grep -v libjudy | \
grep -v 'sqlite3.h' | \
xargs sed -i -e 's/extern \(.*(.*$\)/\1/'
This is a NFC.
