debug: add timestamps for debug messages
Timestamps on debug messages help establish what takes long to process.
Debug messages are print only if DDEBUG flag is passed.
Add timestamps for debug messages. Remove dead code from dprintf dummies
for non-debug builds. Remove timestamps from current debug messages.
