* Catalog of functions supported by device code

* As PostgreSQL allows function overloading, OpenCL also allows it; we can
* define multiple functions with same name but different argument types,
* so we can assume PostgreSQL's function name can be a unique identifier
* in the OpenCL world.
* This convension is same if we use built-in PG-Strom functions on OpenCL.
* All the built-in function shall be defined according to the above naming
* convension.
* One thing we need to pay attention is namespace of SQL functions.
* Right now, we support only built-in functions installed in pg_catalog
* namespace, so we don't put special qualification here.
*
* func_template is a set of characters based on the rules below:
*
* [<attributes>/](c|r|l|b|f|F):<extra>
*
* attributes:
* 'a' : this function needs an alias, instead of SQL function name
* 'n' : this function needs opencl_numeric.h
* 's' : this function needs opencl_textlib.h
* 't' : this function needs opencl_timelib.h
*
* class character:
* 'c' : this function is type cast that takes an argument
* 'r' : this function is right operator that takes an argument
* 'l' : this function is left operator that takes an argument
* 'b' : this function is both operator that takes two arguments
