Cleanup: fewer iostreams related includes from BLI/BKE headers Including <iostream> or similar headers is quite expensive, since it also pulls in things like <locale> and so on. In many BLI headers, iostreams are only used to implement some sort of "debug print", or an operator<< for ostream. Change some of the commonly used places to instead include <iosfwd>, which is the standard way of forward-declaring iostreams related classes, and move the actual debug-print / operator<< implementations into .cc files. This is not done for templated classes though (it would be possible to provide explicit operator<< instantiations somewhere in the source file, but that would lead to hard-to-figure-out linker error whenever someone would add a different template type). There, where possible, I changed from full <iostream> include to only the needed <ostream> part. For Span<T>, I just removed print_as_lines since it's not used by anything. It could be moved into a .cc file using a similar approach as above if needed. Doing full blender build changes include counts this way: - <iostream> 1986 -> 978 - <sstream> 2880 -> 925 It does not affect the total build time much though, mostly because towards the end of it there's just several CPU cores finishing compiling OpenVDB related source files.
