starting braces after function() in new line

[amarts]

Noticed that with the current .clang-format the starting brace of the function is not in the new-line.

But if we use '-style=Mozilla' that specific thing is handled properly (not many other things. Not able to corner what is the exact option.

In the last PR I sent, I changed BreakBeforeBraces from Attach to Linux. It caused all braces to be put into a new line after a function.

I see them correctly formatted in latest update of formatted-dht-common.c.

I think this can be closed. Current formatting seems to work as expected.
