Include Logging and Backtrace?

[fabianfett]

@fabianfett asked:

How many batteries do we want to include and which ones? Logging for sure I guess (SSWG graduated). Backtrace? (SSWG not even in sandbox but within the guides)

@tomerd answered:

logging “feels” right but we need to make sure perf is not hurt

linux-backtrace will be added to sswg soon (eventually just be part of the language), but we need it otherwise you are blind on crashes
