trace: Add trace file name command-line option
This patch adds an optional command line switch '-trace' to specify the filename to write traces to, when qemu starts. Eg, If compiled with the 'simple' trace backend, [temp@system]$ qemu -trace FILENAME IMAGE Allows the binary traces to be written to FILENAME instead of the option set at config-time.
