Make bufchain_prefix return a ptrlen.

Browse Source 
Now that all the call sites are expecting a size_t instead of an int
length field, it's no longer particularly difficult to make it
actually return the pointer,length pair in the form of a ptrlen.

It would be nice to say that simplifies call sites because those
ptrlens can all be passed straight along to other ptrlen-consuming
functions. Actually almost none of the call sites are like that _yet_,
but this makes it possible to move them in that direction in future
(as part of my general aim to migrate ptrlen-wards as much as I can).
But also it's just nicer to keep the pointer and length together in
one variable, and not have to declare them both in advance with two
extra lines of boilerplate.
