[Csnd-dev] extended guard point

Work on PR1848 has brought up one unresolved issue that has been present since we mainstreamed non-pow-two tables.

There are two problems:

1) There is currently no way to tell Csound to create a table with an extended guard point if we do not use a pow-two size.

2) Pow-two+1 sizes are pow-two lengths with extended guard point. There is no way to actually create a table with that size.

A solution for 1) is to find a way to indicate an extended guard point using some form of code (like we do to suppress rescaling)

We can't use negative table numbers because these were used in the past to allow np2 tables.

We can't use negative table numbers because these are used for internal tables.

Negative creation times may be a solution. While I don't like these adhoc codes, there may not be any other means.

Any suggestions, ideas?
