Add a "perQuadrant" parameter to ST_LineToCurve

[strk]

ST_CurveToLine has a parameter to request a number of edges per circle quadrant. For symmetricity the same parameter should be accepted by ST_LineToCurve to control the minimum number of edges per quadrant required to define a curve. See also #2407

NOTE: this change affects liblwgeom interface which may be changed (cleaner) or augmented (only worth to retain backward compatibility). The relevant liblwgeom interface is:

 lwgeom_desegmentize(LWGEOM *);
 lwgeom_segmentize(LWGEOM *, uint32_t);

My suggestion is to change lwgeom_desegmentize to also take an uint32_t (backward incompatible change).

Wouldn't 2.1 be a perfect moment for this ?

no it wouldn't. We called feature freeze already.

Meh, more knobs to twiddle.
