If the stream is receiving control packets like ping, don't count it as
idle. This means you can enable `timeout_opt.keep_alive_ping` on only
one side to get heartbeat.
Make tests that verify current behaviour.
Update documentation to match changes in PR #2718.
Addresses issue #2716
* Use beast exclusive valgrind feature.
* Make the library modular usable.
* Switch to library requirements instead of source. As source puts extra source in install targets.
* Add Beast root dir for includes. As some tests refer to files relative to that.
* Replace relative docca refs with project based.
* Avoid mtuliple openssl configurations.
* Always declare openssl. If it's empty and duplicate it will be ignored.
* Add missing import-search for cconfig/predef checks.
* Add requires-b2 check to top-level build file.
* Bump B2 require to 5.2
* Update copyright dates.
* Move inter-lib dependencies to a project variable and into the build targets.
* Update build deps.
* Update build deps.
* The http/client/body example uses the source header from json instead of the linked library.

fix#2417
This improves inter-conversion between string_view implementations. Some observable differences for users:
- core::string_view no longer supports the .to_string() or .clear() extensions from Utility
- code that relied on .max_size() returning .size(), needs to be fixed to .size() instead
- remove_suffix() and remove_prefix() were more lenient than the standard specs; be sure you don't rely on it clamping the argument to valid range
- BOOST_NO_CXX11_EXPLICIT_CONVERSION_OPERATORS no longer suppresses conversions to std::string
- core::string_view adds .contains() and various bugs fixed
