extract and use FILE_LINE macro

Extract nifty FILE_LINE useful for printk style debugging:

	printk("%s\n", FILE_LINE);

It should not be used en mass probably because __FILE__ string literals
can be merged while FILE_LINE's won't. But for debugging it is what
the doctor ordered.

Don't add leading and trailing underscores, they're painful to type. 
Trust me, I've tried both versions.
