Reintegrate the 1.6.x-r997457 branch:
* r997457, r997466
Fix some error transmission problems in svnserve.
Justification:
It's hard to automatically react to a particular error code when
you can't accurately receive it from the server.
Notes:
r997457 fixes svnserve to send only the "real" error across the
wire in places where there is more than one level of magic
wrapping errors.
r997466 teaches the client to forgive still-broken servers by
ignoring wrapping errors and digging down to find the "real"
error itself. And forgiveness is, as they say, divine.
