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.
