A little bit of code here and there to get more access to

what the console output is.

base/circlebuf.hh:
base/circlebuf.cc:
    add stuff to spit to an ostream
    prepend _ in front of protected member variables
    formatting
dev/console.hh:
dev/console.cc:
    Add DPRINTF to spit out the lines of console data
dev/console.cc:
    little hack to append name() to the file so that we can
    easily get multiple output files.
dev/console.hh:
    TRACING_ON == 1 not defined(TRACING_ON)
