the key command_*() helper functions, fixng the bugs that turned up.

Several of these bugs were from misuse of PRIi64; that's for 64-bit
integers, NOT for "long long" or "u64" (which work best with %lld).

    -jtag.c, interface_jtag_add_ir_scan() [1/2]:
    	- remove temporary scan_size and use tap->ir_length instead
    	- slight loop restructuring to reduce indentation level




git-svn-id: svn://svn.berlios.de/openocd/trunk@1868 b42882b7-edfa-0310-969c-e2dbd0fdcd60

   -jtag.c, interface_jtag_add_dr_out():
        - use pointer 'field' instead of scan->fields[field_count]
        - restructure the main loop to clearly separate the two cases: TAP is not bypassed / TAP is bypassed
          (this is to keep the function similar to interface_jtag_add_dr_scan())
        - fix bug where only the first output field has its tap field set
        - add asserts to verify that target_tap points to the one not bypassed TAP

    -jtag.c, interface_jtag_add_dr_scan():
            - use pointer 'field' instead of scan->fields[field_count]
            - restructure the main loop to clearly separate the two cases: TAP is not bypassed / TAP is bypassed
            - add an assert that each non-bypassed TAP receives at least one field
            - add an assert that checks that no superfluous input fields were passed
