Subject: debug: Print thread name on debug prints
X-Git-Url: http://git.itanic.dy.fi/?p=rrdd;a=commitdiff_plain;h=a12fb50d7366155290a6c004916145f16e52127e

debug: Print thread name on debug prints

Many different threads might be calling the same functions
concurrently. Add the name of the thread so that it becomes more
obvious which thread is emitting the given print.
