This change allows these functions to be called using named-argument notation, which can be helpful for readability, particularly for the ones with many arguments. There was considerable debate about exactly which names to use, but in the end we settled on the names already shown in our documentation table 9.10. The citext extension provides citext-aware versions of some of these functions, so add argument names to those too. In passing, fix table 9.10's syntax synopses for regexp_match, which were slightly wrong about which combinations of arguments are allowed.
