* aclk: link libcap after libwebsockets for legacy build
libwebsockets requires libcap. without this, we get
errors about undefined libcap functions that libwebsockets
uses.
This is needed for building aclk-legacy.
* aclk: create log for HTTP requests similar to legacy version.

* Do not accept a path when using --with-bundled-lws.
The bundled library is always placed under externaldeps/libwebsockets,
when using the netdata-installer.sh script. When this option is missing,
we look for the system-wide installed version.
* Do not accept a path when using --with-bundled-libJudy.
The bundled library is always placed under externaldeps/libJudy. When
the option is not given, we look for the system-wide installed version.
* Use absolute header paths for repo-internal deps.
* Use absolute library paths for repo-internal deps.

* Remove code for bundling the dashoard on install.
* Bundle the dashboard code directly into the agent repo.
This diffstat looks huge, but it’s actually relatively simple. The only
_actual_ changes are in the Makefiles, `configure.ac`, and the addition of
`generate_dashboard_makefile.py`. Everything else consists of removing
files that are included in the dashboard tarball, and extracting the
contents of the tarball into `web/gui/dashboard`.
* CI cleanup.
* Automate bundling of the dashboard code.
This replaces the makefile generator script with one that handles
bundling of the dashboard code in it’s entirety, and updates the GHA
workflow used for generating dashboard PRs to use that instead of the
existing shell commands.
It also removes the packaging/dashboard.* files, as they are no longer
needed.

* Add a way to get build configuration info from the agent.
This adds a new option to the `-W` switch called 'buildinfo'. When
invoked with this argument, Netdata will print it's version, the
configure options, and a list of optional features and whether they are
enabled or not.
This is intended to serve three purposes:
* It allows developers to more quickly get an idea of how Netdata was
built when triaging bug reports.
* It provides an easier way to validate changes to the build system that
affect optional features during the development cycle.
* It provides an easier way to build CI workflows that validate that
building under a given set of constraints results in a feature being
enabled or not.
The actual implementation is a bit large but overall exceedingly simple,
consisting of a set of preprocessor directives to extract optional
feature state information from config.h and then a series of printf()
calls to actually report this info (which should end up optimized by
smart compilers due to all the arguments being compile-time constants).
* Added zlib to optional libraries.
* Added remaining optional plugins to buildinfo output.
* Changed formatting to be more human friendly.
* Add remaining optional libraries.
* Fix up formatting to be even more human friendly.
* Fix typo in buildinfo output.
* Remove unused variable.
* Fixed spelling of config.h option name.
* Update daemon/buildinfo.c

of it. (#9776)
* Add installer code to bundle libJudy.
* Update libJudy build to work on more systems.
* Added libtool to deps.
* First part of configure changes - detection of library
* Configure change part two: integrating flags into the build
I've tested the build works and that the symbols end up correct in the compiled binary, but I have not tested that
dbengine is working properly after the changes.
* Add required configure options for bundling libJudy.
* Bail early if a libJudy build step fails.
* Added messges for specific reasons libJudy is being built.
* Fix bail condition for bundling failures.
We don't care about whether the cloud is required or not, just whether
the user asked for a local build of libJudy or not.
* Fix logic for deciding when to bundle libJudy.
* Fix judy build to clean up properly if it fails.

* Add DEB/RPM package build tests to Travis.
* Add working support for bundling eBPF in binary packages.
* Show stdout and stderr from commands run in LXC.
* Add proper bundling code for libbpf.
* Use AC_CHECK_FILE for libbpf.a external dep.
This way it gets properly logged in both configure output and the
configure log.

Adds ACLK charts
|
|
This PR adds (inactive) support that we will use to fill the gaps on chart when a receiving agent goes offline and the sender reconnects. The streaming component has been reworked to make the connection bi-directional and fix several outstanding bugs in the area.
* Fixed an incorrect case of version negotiation. Removed fatal() on exhaustion of fds.
* Fixed cases that fell through to polling the socket after closing.
* Fixed locking of data related to sender and receiver in the host structure.
* Added fine-grained locks to reduce contention.
* Added circular buffer to sender to prevent starvation in high-latency conditions.
* Fixed case where agent is a proxy and negotiated different streaming versions with sender and receiver.
* Changed interface to new parser to put the buffering code in streaming.
* Fixed the bug that stopped senders from reconnecting after their socket times out - this was part of the scaling fixes that provide an early shortcut path for rejecting connections without lock contention.
* Uses fine-grained locking and a different approach to thread shutdown instead.
* Added liveness detection to connections to allow selection of the best connection.
