glib/girwriter.c
Garrett Regier 96deb9ede5 girepository: Support GError exceptions on callbacks 
Generalize "throws" attribute to SignatureBlob which can be used by all
callable blob types. Keep FunctionBlob and VFuncBlob throw attributes
around and functional for compatibility. Refactor girwriter.c to write
out throws attribute for all callable types.

Based on a patch by Simon Feltman.
