Progresses on action items/issues resolutions

From rom the F2F AI [1], I made the following progresses:

* ACTION Dom: add paragraph in 4.3 introduction about various types of
extension creators. 

I've added the following text in the editors version of SpecGL [2],
under "What does it mean" of GP19
"Extensions can be created in different contexts: directly by
implementers, in other specifications, etc."

* ACTION Dom: Reword text regarding " error processing for non language
or protocol specs" (bug Issue 1154)

I've reworded the what does it mean of GP 23 as follows:
"For each class of product that is affected by an error condition,
address how the error is handled. For instance:  for a language, address
what effect an error (be it syntactic or semantic) in the input has to a
processor of this language; for a protocol, address how a party to this
protocol should behave when a bogus message is received; for an A.P.I.,
indicate what exceptions are raised."

* ACTION Dom: Add "warn against untested hooks" as technique in 5 GP B
Instead of 5 GP B where I don't think it fit very well, I made it a
technique of GP18, as follows
"Avoid "untested hook": if an extensibility mechanism is defined, make
sure it is well tested during the implementation phase; experience has
shown that untested extensibility just doesn't work"

I don't think any of these are controversial, so unless someone
specifically requests it, I don't recommend we spend any more time on
this during the call. Of course, suggestions and corrections are
welcomed, as always.
