Regarding APIs, are you talking about multiple libraries (libsvn_fs,
libsvn_fs_bdb, libsvn_fs_mysql, etc.), like RA?

I ended up abstracting things a little bit, that is I've moved all
remaining BDB-specific stuff into the bdb/ dir, except for a
svn_fs_new_bdb() function, and created a vtable that is set up by that
function... it's not very elegant (especially since I've not bothered
with re-indenting after all the searching-and-replacing!) but I've got
it working again.

The problem is that the operations provided by the vtable are specific
to the current BDB schema... they won't be much use if a more different
implementation (such as storing files as orginary files) comes along.

Happy Subversion 1.0 day.
