Move scriptc to script_api/include.

Part 1 of the directory re-organization.  We're renaming the "api" directory
to "script_api" directory to distinguish between our control api (java or c++)
and our script api.

We're also moving the scriptc directory under that newly renamed directory,
and change its name to the more appropriate "include".

Test: scriptc/generate.sh
Test: compiled ImageProcessing_jb
