treewide: improve logging

Browse source 
Provide multi-priority syslog() based logging to improve user and
developer experience. Add dawnlog_* functions and macros to convert
printf() family and perror() logging to syslog() family. Removed
unnecessary sprintf() for building log strings (embed format directly).
Add local config settings for log level. Add command line parameters for
log level and destination. Set default log level to suppress a lot of
previously noisy messages. Restore some previously removed noisy
messages as DEBUG level in case they help in future. Eliminate DAWN_NO_OUTPUT static code checks which are no longer used.
