Kevin O'Connor 5ca132eafa stepcompress: Fix rounding error when interval=0
In the rare case where the step generation code finds an interval of
zero, it was possible for an integer division of a negative number to
cause an incorrect result.  Fix that by using the idiv_up() and
idiv_down() helpers.

Kevin O'Connor c3fe3d0d2c stepcompress: Remove no longer needed stepcompress_set_homing()
Now that homing is implemented via "drip moves", it is no longer
necessary for the stepcompress code to have special homing logic.

Kevin O'Connor 8f747e2720 kin_cartesian: Remove stepcompress_push_const()
All the kinematic code now uses the iterative solver to generate
steps.  Remove the old stepcompress_push_const() mechanism.

Kevin O'Connor 8a830ff0ce chelper: Compile with gcc -fwhole-program option
Use the -fwhole-program option when compiling the host C code.  This
makes it easier to support inlining across C files.

Kevin O'Connor 15248706ae chelper: Move the host C code to a new klippy/chelper/ directory
Move the C code out of the main klippy/ directory and into its own
directory.  This reduces the clutter in the main klippy directory.
