Fix segfault in deformation

2018-04-13T21:17:49+00:00

When transforming coordinates outside the grid model the deformation
operation failed spectatularly. This is now fixed by checking that the
coordinate is inside the grid. If it isn't an error is returned and a
debugging log message is issued.

Closes #934

Refactor grid shift functions.

2017-10-29T13:02:13+00:00

This refactoring of the grid shift functions allows for easier access to
the actual grid values, as well as making it possible to perform
horizontal grid shift on a single coordinate without using the
pj_apply_gridshift* functions. The latter simplifies the execution path
of the forward and inverse functions in PJ_hgridshift.c.

This commit introduces proj_*grid_init, proj_*grid_value
and proj_hgrid_apply. The init functions initialises horizontal and
vertical grids respectivelive (wrappers for pj_gridlist_from_nadgrids
with simpler parameters). The proj_*grid_value functions returns the
specific grid value at coordinate lp. The proj_hgrid_apply function
applies the grid offset to the input coordinate and outputs the adjusted
coordinate.
