inconsistent error codes in Appendix F

[bashbaug]

After #950, the error code appendix table has an error code for cl_khr_icd, but no error codes for other extensions. Do we want to include error codes for extensions in this table, or should it only contain error codes for the core spec?

The primary reason for the error code appendix was to have a place for the error codes to link to (although the text description for each of the error codes is also a nice benefit). If there is already some other place the extension error codes can link to we can use that instead, although currently many enum error codes do not seem to link to anything.

Discussed in the March 26th teleconference. Preference is to include error codes for extensions in the same table.

Ideally we would generate the error codes from the XML file, but that can come later.
