Doc update: say "jtag newtap ... -disable" records the state after exiting the RESET state, matching the only implementation we're working with so far (TI ICEpick-C). Matching code updates. Now we can be sure that the "enabled" flag value is correct after JTAG resets. git-svn-id: svn://svn.berlios.de/openocd/trunk@2246 b42882b7-edfa-0310-969c-e2dbd0fdcd60
