Merge #7457
7457: Add no-buffering file logging and wait for a debugger option. r=vsrs a=vsrs Adds two command line flags: `--no-buffering` and `--wait-dbg`. Not sure if someone else needs this, but personally I found both flags extremely useful trying to figure out why RA does not work with Visual Studio. Or better to say why Visual Studio does not work with RA. Co-authored-by: vsrs <vit@conrlab.com>
