warnings

So suppose libsvn_wc is working, deep down in a bunch of call frames,
and it's trying to do 5 things. However, it wants to emit a warning
about the 2nd action, and then move on to the 3rd, 4th, and 5th
actions.

Right now, we have no way to do this. If I throw a "non-fatal"
svn_error_t, the top-most recipient can choose not to quit. But big
deal; I've lost my call stack!

It would be great to register some kind of "warning" function with
libraries; this function would need to be available at all call-stack
levels, of course. Perhaps one way to do it is to sneak it into the
global error pool somehow?

Thoughts?
