[tex-live] Primitive parity, \expanded and \Ucharcat

Hello Joseph and all,

I made a branch for \eptexbanner for e-(u)pTeX as
https://github.com/texjporg/tex-jp-build/tree/banner.
I think it would be more convenient to use a common name for these "banner"
primitives such as \enginebanner, rather than different name for each engine 
(\pdftexbanner, \xetexbanner etc.).
