Fix issue #3819: 'svn update' touches file externals in ../sibling/ too.
* subversion/libsvn_client/client.h
(svn_client__handle_externals): Add TARGET parameter.
* subversion/libsvn_client/externals.c
(handle_externals_desc_change_baton): Grow TARGET_ABSPATH member.
(handle_externals_desc_change): Document KEY parameter, and ignore
externals not under TARGET_ABSPATH.
(svn_client__handle_externals): Add TARGET parameter, and use it to
populate the baton's TARGET_ABSPATH member.
* subversion/libsvn_client/switch.c
(switch_internal): Pass TARGET to svn_client__handle_externals().
