+- Fix handling of variables between multiple command line "-c" and "-f"

+ command/script are unset before the next one is invoked.

- Isolate all TCL command support:
- Pure C CLI implementations using --disable-builtin-tcl.
- Allow developers to build new dongles using OpenOCD's JTAG core.

+@quotation Important
+At this writing (October 2009) the command line method has
+problems with how it treats variables.
+For example, after @option{-c "set VAR value"}, or doing the

Here we will focus on the simpler solution: one user config
file, including basic configuration plus any TCL procedures
to simplify your work.
