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.

QTemporaryFile creates temporary files, so they might get removed even if they
are renamed. Copy the downloaded temporary file instead.
