Hi Alexey,

From a brief check it looks like str_has_prefix() is already quite
common with 94 uses. So the path of least resistance is to make
everything self consistent and add str_has_suffix().

I agree it's a bit of a mouthful and not so common in other languages.
Once this more complicated set gets through we could always do a simple
search and replace change it to anything we like. But it would touch
_lots_ of different drivers and trees, so it would be hard to justify.

Thanks
James
