trace: add support for 'trace wipe'
Implement a 'trace wipe' command to delete the currently accumulated
trace data. This comes handy when someone needs to trace a particular
command. For example:
=> trace pause; trace wipe
=> trace resume; dhcp; trace pause
=> trace stats
=> trace calls 0x02100000 0x10000000
=> tftpput $profbase $profoffset 192.168.0.16:trace.bin
