Add resolver support for 'added file vs unversioned file' with update/switch.
Make the conflict resolver handle conflicts recorded during update and switch
operations where a newly added file was obstructed by an unversioned file.
The resolver will now offer the 'incoming_added_file_text_merge' option
in this case, allowing users to merge unversioned files with incoming
newly added files.
Because 'merge' currently skips unversioned files and does not even record
a conflict for them, this change only affects 'update' and 'switch'.
Supporting unversioned file conflicts during merges can be revisited later.

(resolve_merge_incoming_added_file_text_update): Handle unversioned files
in addition to versioned files.
(configure_option_incoming_added_file_text_merge): Enable this option
for the case where the local file is unversioned.
test_switch_file_add_vs_unversiond_file, test_funcs): New tests.
