backend abandon

["Howard Chu" <hyc@highlandsun.com>]

I couldn't find this discussed before on -devel, so I'll ask (again? I
vaguely recall discussing this before) now. slapd/abandon.c just sets the
o_abandon flag for every operation associated with a given connection. There
is a per-backend abandon function pointer provided in the backendInfo, but
no slapd code ever references or executes that function. Is this abandon
pointer obsolete, or just an oversight?

I note that most of the backends have empty stubs for their abandon entry
point, but back-shell actually tries to do something meaningful there. Of
course, none of that code ever gets executed...
