Adam Wulkiewicz 1da9113046 [relate][get_turns] Support spikes for Linear in relate(L/A). Fix errors in get_turns for L/L and L/A.
relate_linear_areal:
handle non-endpoint x-c turns pair generated for a collinear spike.

relate/follow helpers:
fix turn_on_the_same_ip to use fraction instead of dimension.

get_turns:
L/L and L/A - use base_turn_handler::assign_point() to set fractions properly for collinear-opposite spikes.
L/A - fix the condition in calculate_spike_operation() used to check if a spike goes into the interior or exterior.
