Remove the 'depth' parameter from svn_cl__resolve_postponed_conflicts(), as
it was mis-used and unnecessary (and undocumented).

The function resolves the conflicts on a pre-selected set of specific paths.
It was resolving to the specified depth within each such path, but the
callers were mistakenly passing the depth of the overall merge/update/switch
operation.

* subversion/svn/cl.h,
  subversion/svn/conflict-callbacks.c
  (svn_cl__resolve_postponed_conflicts): Remove the 'depth' parameter.

* subversion/svn/merge-cmd.c
  (svn_cl__merge): Adjust caller.

* subversion/svn/switch-cmd.c
  (svn_cl__switch): Adjust caller.

* subversion/svn/update-cmd.c
  (svn_cl__update): Adjust caller.
