update traps documentation (unfinished)

* doc/ref/Makefile.am:
* doc/ref/guile.texi:
* doc/ref/scheme-debugging.texi: Remove scheme-debugging.texi, which
  only described tracing. Tracing documentation is now in
  api-debugging.

* doc/ref/scheme-using.texi (Evaluating Scheme Code): Remove reference
  to source traps, as that section is going away.

* doc/ref/api-modules.texi (Included Guile Modules): Remove reference to
  Tracing. This section is a little silly, anyway...

* doc/ref/api-evaluation.texi (VM Behaviour): Remove section, it is in
  api-debugging now.

* doc/ref/api-debug.texi (Stacks, Frames): Rename sections from
  "Examining the Stack" and "Examining Stack Frames", respectively.
  (Traps): Update for current API. A big and not-quite-finished update.

-If you type @kbd{C-u} before one of these commands, GDS will
-immediately pop up a Scheme stack buffer, showing the requested
-evaluation, so that you can single step through it.  (This is achieved
-by setting a @code{<source-trap>} trap at the start of the requested
-evaluation; see @ref{Source Traps} for more on how those work.)  The
-Scheme stack display, and the options for continuing through the code,
-are described in the next two sections.
