- src/jtag/core.c: contains the low-level JTAG TAP and scanning routines.
- src/jtag/tcl.c: contains high-level JTAG TCL commands that use the core.
- Remove static keywords from routines in core.c, extern from tcl.c:
  - jtag, jtag_interface global variables
  - jtag_{examine,validate}_chain and jtag_tap_{init,free} functions
- Added myself to the copyright header in both of these files.
- Used 'svn cp' to add files, so versioning was preserved for both.

- Don't let disabled TAPs be set as the current target

    * Remove undesirable "chain position" number; we discourage using them

       + make them long enough for current usage
       + improve labels, removing guesswork
       + "TapName" label patches scan_chain output
    * Highlight the "current" target
    * Display "tap disabled" as a new pseudo-state
    * Update docs accordingly
