I had a look at the interface, and it looks fine as a starting point.

Reading the comments to svn_delta_op_t, I noticed the restriction that
a copy from the source to the target (the svn_delta_source op) can't
cross the source/target boundary. Neither the Vdelta algorithm nor the
vcdiff format have that restriction. Was this meant to make it easier
to stream the source and target data?

May I suggest a small change: s/ap_off_t/apr_off_t/g .

This brings me to another question I've been meaning to ask. Is it
safe to assume we'll be using the APR library throughout the code?
I noticed a copy of glib is in the repository, too. APR and glib
overlap in several places. Which is preferred?
