* Remove check locks and NETDATA_VERIFY_LOCKS as it is not needed anymore
* 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.
* Remove allocations when smoothing samples buffer
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

* 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
* added dbengine2 files in CMakeLists.txt

* old dbengine statistics become "dbengine io"
* do not enable ML resource usage charts by default
* unify ml chart families, plugins and modules
* cleanup query plans from query target
* cleanup all extent buffers
* added debug info for rrddim slot to time
* rrddim now does proper gap management
* full rewrite of the mem modes
* use library functions for madvise
* use CHECKSUM_SZ for the checksum size
* fix coverity warning about the impossible case of returning a page that is entirely in the past of the query
* fix dbengine shutdown
* keep the old datafile lock until a new datafile has been created, to avoid creating multiple datafiles concurrently
* fine tune cache evictions
* dont initialize health if the health service is not running - prevent crash on shutdown while children get connected
* rename AS threads to ACLK[hostname]
* prevent re-use of uninitialized memory in queries
* use JulyL instead of JudyL for PDC operations - to test it first
* add also JulyL files
* fix July memory accounting
* disable July for PDC (use Judy)
* use the function to remove datafiles from linked list
* fix july and event_loop
* add july to libnetdata subdirs
* rename time_t variables that end in _t to end in _s
* replicate when there is a gap at the beginning of the replication period
* reset postponing of sender connections when a receiver is connected
* Adjust update every properly

* void unused variable
* void unused variables
* fix indentation
* entries_by_time calculation in VD was wrong; restored internal checks for checking future timestamps
* macros to caclulate page entries by time and size
* prevent statsd cleanup crash on exit
