* Move mqtt_websockets under aclk/
* Use relative paths for includes from mqtt_websockets
...in order to reduce the number of header
search paths that we use when building the
agent. Ideally, we'd make each component a
standalone library target from CMake's
perspective but more work needs to be done
before we are able to do this.
* Remove unused files.
* Make licensing information consistent across all files.
* Flatten the hierarchy of source files.
* Use `-Werror` when checking compiler flags.
This should ensure that Clang rejects unknown flags correctly instead of
blindly eating some of them.
* Explicitly check C and C++ flags separately.
This should better handle the unusual case of mismatched compilers.
* Properly use Clang for C++ in our CI checks that build using Clang.
* Apply suggestions from code review
Co-authored-by: Ilya Mashchenko <ilya@netdata.cloud>
* Use functions and loops when possible.
* Fix typos and broken loops.
* Fix more typos.
* Fix bogus commas.
* Fix caching of compiler flag checks.
* Fix flag variable names to make them behave correctly in checks.
CMake adds a preprocessor define with the name of the variable being
defined by a compiler flag check, so we need to ensure not only that
the variable name is unique, but also that it is a valid name for a C
preprocessor definition.
* Fix scoping.
* Fix botched merge during previous rebase.

These functions report some issues when running
the address sanitizer with `-W unittest`. We
want to run the sanitized binary on Github PRs
to catch newly-introduced issues. FIXMEs were
added so that we know which ones already existed
prior to this change.
* Add cmake option to use address sanitizer
* Run unit tests with address sanitizer.
* Specify attribute before the function declaration.
* Disable hardening flags.
* log2journal should not be linked against libnetdata; netdatacli is now linked against libnetdata so it does not need to redefine functions in libnetdata

This fixes most of the scripts installed by cmake so that they correctly
have execute permissions.
We need to do more work than just this (such as properly handling the
SUID bit), but this is a solid starting point.

logsmanagement_function_execute_cb() is replaced by
logsmanagement_function_facets() which adds facets support to logs
management queries.
Internal query results header now includes additional fields
(log_source, log_type, basename, filename, chartname), that are used as facets.
Queries now support timeout as a query parameter.
A web log timestamp bug is fixed (by using timegm() instead of mktime().
web_api_v1 logsmanagement API is only available in debugging now.
