0029972: Intersection curve has a weird gap in the middle of it

Browse Source 
1. The condition of WLine breaking (in IntWalk_IWalking algorithm) has become more independent of the input tolerance.

2. Currently the algorithm of IntPatch_Points of WLine processing depends on the algorithm of obtaining the WLine.

3. The methods IntSurf_LineOn2S::Add(...) and IntSurf_LineOn2S::SetUV(...) have become not inline (see the message ~0077431 in the issue #29866).
