* 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

* 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

* 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

* 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.

* Revert "Use llvm's ar and ranlib when compiling with clang (#13854)"
This reverts commit a9135f47bbb36e9cb437b18a7109607569580db7.
* Profile plugin
* Fix macos static thread
* Add support for replication
- Add a new capability for replication, when not supported the agent
should behave as previously.
- When replication is supported, the text protocol supports the
following new commands:
- CHART_DEFINITION_END: send the first/last entry of the child
- REPLAY_RRDSET_BEGIN: sends the name of the chart we are
replicating
- REPLAY_RRDSET_HEADER: sends a line describing the columns of the
following command (ie. start-time, end-time, dim1-name, ...)
- REPLAY_RRDSET_DONE: sends values to push for a specific start/end
time
- REPLAY_RRDSET_END: send the (a) update every of the chart, (b)
first/last entries in DB, (c) whether the child's been told to
start streaming, (d) original after/before period to replicate.
- REPLAY_CHART: Sent from a parent to a child, specifying (a)
the chart name we want data for, (b) whether the child should
start streaming once it has fullfilled the request with the
aforementioned commands, (c) after/before of the data the parent
wants
- As a consequence of the new protocol, streaming is disabled for all
charts on a new connection. It's enabled once replication is finished.
- The configuration parameters are specified from within stream.conf:
- "enable replication = yes|no"
- "seconds to replicate = 3600"
- "replication step = 600" (ie. how many seconds to fill per
roundtrip request.
* Minor fixes
- quote set and dim ids
- start streaming after writing replicated data to the buffer
- write replicated data only when buffer is less than 50% full.
- use reentrant iteration for charts
* Do not send chart definitions on connection.
* Track replication status through rrdset flags.
* Add debug flag for noisy log messages.
* Add license notice.
* Iterate charts with reentrant loop
* Set replication finished flag when streaming is disabled.
* Revert "Profile plugin"
This reverts commit 468fc9386e5283e0865fae56e9989b8ec83de14d.
Used only for testing purposes.
* Revert "Revert "Use llvm's ar and ranlib when compiling with clang (#13854)""
