removed an unneeded argument
Increased blend radius for short segments

For nearly-tangent blends, a minimum-size the blend arc can be very short and still
satisfy the minimum radius to be within limits. However, this leads to
sudden short pulses of acceleration during corners, which could
introduce vibrations.

The modification here grows the radius until the amount of each segment
consumed is the same as the equivalent parabolic blend.
Fixed exact stop error in tpCheckEndCondition
Added axis remote style commands to test-all.sh
Enforce exact stop at transitions between feeds and rapids
Major refactor of line-line blend calculation into separate source file
Fixed broken check for minimum angle
Moved more utility functions to blendmath source
Refactored blending completely to abstract main calculations

Blend arc calculations before were a mess of local variables, and most
of the useful calculations were buried in the tpCreateBlendArc function.
This refactor pushes much of the actual math into the blendmath file.
Critically, this change also isolates the blend "parameters" from the
geometry, so that the same blend calculations can be reused for line-arc
blends, multi-axis blends, etc.
Added stretch functions for line and circle
Added trim fields and misc fixes
Refactored TCQ functions into separate source file
Working arc-arc for all cases, needs robustness testing

Fix for consumed line length / drift bug
Implemented line-arc and arc0line
Removed old line-arc code
Added ripple control
Added parabolic equivalent sizing to reduce accel ripple
