Prefix inverse and forward functions by their projection names

This is mostly to have better OSSFuzz report. Currently a lot
of bug summaries are like
`proj4/standard_fuzzer: Divide-by-zero in s_inverse`

By prefixing the projection name, we will get better reports, like
`Divide-by-zero in airy_s_inverse`

This also makes it slightly easier to set a breakpoint by
function name.
