logging: subsystem major redesign

Browse source 
Adding new implementation of logging subsystem. New features
includes: support for multiple backends, improving performance
by deferring log processing to the known context, adding
timestamps and logs filtering options (compile time, runtime,
module level, instance level). Console backend added as the
example backend.
