debugging: Employ new scheme for code snippets

In sh/awk code, it is not possible to put inline comments on
lines ending with "\". To avoid continuations, shorten variable
names in datablows.sh.

As source files of snippets are searched under CodeSamples/,
put a symbolic link to utilities/datablows.sh under
CodeSamples/debugging.

"grep -r" doesn't follow symbolic links, so use the "-R" option
instead.
