Change int -> bool where applicable throughout varobj

This patch changes all the "int" I could find in varobj.{c,h} that are
really boolean values to use bool.  I followed the ramifications
(parameters and return values of exported functions), so the changes
spilled a bit on other, related files (ada-varobj.c and c-varobj.c).
