Use "%option prefix" to set API names in ecpg's lexer.
Clean up some technical debt left behind by commit 72b1e3a21: instead of quickly hacking the name of base_yylex() with a #define, set it properly with "%option prefix". This causes the names of pgc.l's other exported symbols to change as well, so run around and modify the outside references to them as needed. Similarly, make pgc.l's external references to base_yylval use that variable's true name instead of a macro. The reason for doing this now is that the quick-hack solution will fail with future versions of flex, as reported by Дилян Палаузов. Hence, back-patch into 9.6 where the previous commit appeared, since it's likely people will build 9.6 with newer flex versions during its lifetime.
