* Fix bad memory allocation / cleanup
* Cleanup ACLK sync initialization (part 1)
* Don't update metric registry during shutdown (part 1)
* Prevent crash when dashboard is refreshed and host goes away
* Mark ctx that is shutting down.
Test not adding flushed pages to open cache as hot if we are shutting down
* make ML work
* Fix compile without NETDATA_INTERNAL_CHECKS
* 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.
* check new ml code
* first save the database, then free all memory
* dbengine prep exit before freeing all memory; fixed deadlock in cache hot to dirty; added missing check to query engine about metrics without any data in the db
* Cleanup metadata thread (part 2)
* increase refcount before dispatching prep command
* Do not try to stop anomaly detection threads twice.
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.
* set the orphan flag when loading archived hosts
* track worker dispatch callbacks and threadpool worker init
* make ML threads joinable; mark ctx having flushing in progress as early as possible

* Cleanup metadata thread (part 4)
* Skip metadata host scan when running unittest
* unittest support during init
* dont use all the libuv threads for queries
* break an infinite loop when sleep_usec() is interrupted
* ml prediction is a collector for several charts
* sleep_usec() now makes sure it will never loop if it passes the time expected; sleep_usec() now uses nanosleep() because clock_nanosleep() misses signals on netdata exit
* worker_unregister() in netdata threads cleanup
* moved pdc/epdl/deol/extent_buffer related code to pdc.c and pdc.h
* fixed ML issues
* removed engine2 directory

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.
