libpng 1.5.0 compat : remove direct use of members of png_struct_def

Reported by: Even Rouault Owned by: Even Rouault
Priority: normal Milestone: 1.8.1
Component: GDAL_Raster Version: unspecified
Severity: normal Keywords: png

Description

Since libpng 1.5.0, the png_struct_def is an opaque type and applications should use appropriate getters to avoid compilation errors.

This affects the error_fn and io_ptr members that GDAL uses. They should be replaced by png_get_error_ptr() and png_get_io_ptr(), that exist since libpng 1.0 (at least), so this is safe to use them unconditionaly.
