Change tracing from qDebug() to use cutelogger, which is available under the
LGPL2.1. This allows to automatically add filename and line number to the log,
and also provides multiple log levels.

Move class-less functions in utils.cpp into a new Utils class and make the old
functions static. This prevents clashes with system C functions. Rename some
functions to avoid macro problems (check() is a macro on OS X). Split out the
RockboxInfo class into a separate file.
