2019-02-14	deformation: Replace +t_obs with +dt	Kristian Evers
	The +t_obs parameter was confusing for users since it effectively overwrote the observation time in input coordinates. To make it more clear what is the operation is doing, users are now required to directly specify the time span for which they wish to apply a given deformation. The parameter +dt has been added for that purpose. The new parameter is mutually exclusive with +t_epoch. +dt is used when deformation for a set amount of time is needed and +t_epoch is used (in conjunction with the observation time of the input coordinate) when deformation from a specific epoch to the observation time is needed.

	c6ab83f5742bc5ac6f9cb9a8b2a4f1ea241b6f63 already removed their availability in user facing application, but the library code remained, and appeared to be unused by the rest of the library, and not available to library users, the API being only in proj_internal.h. So remove all remains.
