Remove old pj_ memory (de)allocation functions

2020-11-20T15:40:40+00:00

Gone are pj_malloc, pj_calloc, pj_dalloc and pj_dealloc. Their primary
function as API memory functions in proj_api.h is no longer there and
the other use as a workaround for old errno problems is no longer valid
either.

Replaced with malloc and free across the codebase.

Add +proj=col_urban projection, implementing a EPSG projection method used by a number of projected CRS in Colombia (fixes #589)
