svf: new command line options -noreset and -addcycles

-noreset: when using several SVF input files in a sequence it is not always
 desireable to have a JTAG reset between the execution of the files.
 The -noreset option skips this unwanted reset.

-addcycles <x>: some tests rely on a certain number of extra clock cycles
 between the actual JTAG commands. The -addcycles option injects a number
 x cycles after each SDR instruction.
