Use "%option prefix" to set API names in ecpg's lexer.
Back-patch commit92fb649 into the pre-9.6 branches.Without this, ecpg fails to build with the latest version of flex.It's not unreasonable that people would want to compile our old brancheswith recent tools. Per report from Дилян Палаузов.Discussion:https://postgr.es/m/d845c1af-e18d-6651-178f-9f08cdf37e10@aegee.org
