This is actually in the PEP: the new types are
ssizeargfunc
ssizessizeargfunc
ssizeobjargproc
ssizessizeobjargproc
lenfunc
readbufferproc
writebufferproc
segcountproc
charbufferproc

These replace
intargfunc
intintargfunc
intobjargproc
intintobjargproc
inquiry (partial)
getreadbufferproc
getwritebufferproc
getsegcountproc
getcharbufferproc
