Regex variant of data-harvest complete

Crude complex in-line data-extraction using regex works. This includes
line-index sub-matching (new requirement from today, see previous commits in
doc/). New script provided for harvesting CPU-freq from /proc/cpuinfo. This
has the advantage of not requiring process to be euid=root, but also shows
some of the drawbacks:

* Analyze gets less precise due to being further away from source
* Analyze interfere more due to more work per sample

Main reason for this was however not this file alone. Rather in general the
ability to extract more data from complex files.

Not tested: sub_signals on same line (lack good target with suitable file to
test against).
