Add mlog: Merge log files by timestamp

mlog reads lines from multiple log files and prints them in
chronological order. The files need to start with comparable timestamps.
mlog prints the oldest line first, thus preserving relative order.

mlog behaves like a combination of 'sort -m' and 'tail -f'.
