tweak new "translating ..." text



Fix formatting and layout bugs in the new "translating configuration
files" bit.  Make it a section within the chapter about config files.
Add a crossreference.

Because this is so very board-specific, and chip-specific, no examples

Instead, look at the board config files distributed with OpenOCD.

If you have a configuration file for another hardware debugger
or toolset (Abatron, BDI2000, BDI3000, CCS,
Lauterbach, Segger, Macraigor, etc.), translating
it into OpenOCD syntax is often quite straightforward. The most tricky
part of creating a configuration script is oftentimes the reset init
sequence where e.g. PLLs, DRAM and the like is set up.
One trick that you can use when translating is to write small
Tcl proc's to translate the syntax into OpenOCD syntax. This
Tcl procedures to translate the syntax into OpenOCD syntax. This
can avoid manual translation errors and make it easier to
convert other scripts later on.
