[buffer][fix] fix output for generated linestrings with two equal points only
...
It now simplifies first and removes second point if necessary. Also it is
defensive such that generation is stopped if length is 0.
Including unit tests.

[buffer] support degenerate linestrings containing one point. In that
...
case point-buffer is applied. Including updated unit tests

[buffer][fix] In rare cases an extra ring was traversed and created. Fixed, that ring is
...
discarded now. This fixes behaviour of assign_parents with positive-rings in positive-rings (when
check_for_orientation is true; normally (for overlay) it is false)
It also reverses a negative-only ring so fixes a linestring_buffer testcase.
For multi-polygon it fixes new testcase rt_u2 found by recursive-polygon-buffer test

[buffer][test] enabled field_sprayer test, added aimes-167 test
...
Both tests are disabled for flat-ends for the same reason: flat ends should
be intersected with helper-segments too

[buffer][fix] Fix limit for consideration as continue, as it was too high
...
(for Aimes test or in general cases using lat long)
Including addition of unit test (aimes181)

[buffer][test] join/end strategies are now arguments, such that we can change
...
the default without changing the tests.
This only changes the parameter / involves many lines but nothing else is changed.

[buffer] use endcap strategy for spikes. Check jointype also (again)
...
for line-line intersection because it is based on buffered segments.

[buffer] add join_selector and use it before generating the join.
...
This moves responsibility of generation to the calling code, removes it
from the join strategies. It also enables using the end-strategy for the
spikes

for tolerance which was too high. Added unit test
