Merge branch 'egil/lcnt' into ccase/r13b04_dev
* egil/lcnt: Add test suite for lcnt in tools Add lcnt:rt_opt/1 bindings to erts_debug Add runtime option to enable/disable lcnt stats Add auto width on string output Add lcnt documentation Add lock profiling tool OTP-8424 Add lock profiling tool. The Lock profiling tool, lcnt, can make use of the internal lock statistics when the runtime system is built with this feature enabled. This provides a mechanism to examine potential lock bottlenecks within the runtime itself. - Add erts_debug:lock_counters({copy_save, bool()}). This option enables or disables statistics saving for destroyed processes and ets-tables. Enabling this might consume a lot of memory. - Add id-numbering for lock classes which is otherwise undefined.
