async_wrap: use more specific providers

Instead of wrapping several providers into PROVIDER_CRYPTO, have them
all be named after their class. Rename other providers to also match
their class names. With the exception of Parser. Which is actually
HTTPParser.

Add PROVIDER_LENGTH to make better checks in WrapperInfo().
