Fix various sparse warnings in the git source code
There are a few remaining ones, but this fixes the trivial ones. It boils down to two main issues that sparse complains about: - warning: Using plain integer as NULL pointer Sparse doesn't like you using '0' instead of 'NULL'. For various good reasons, not the least of which is just the visual confusion. A NULL pointer is not an integer, and that whole "0 works as NULL" is a historical accident and not very pretty. A few of these remain: zlib is a total mess, and Z_NULL is just a 0. I didn't touch those. - warning: symbol 'xyz' was not declared. Should it be static? Sparse wants to see declarations for any functions you export. A lack of a declaration tends to mean that you should either add one, or you should mark the function 'static' to show that it's in file scope. A few of these remain: I only did the ones that should obviously just be made static. That 'wt_status_submodule_summary' one is debatable. It has a few related flags (like 'wt_status_use_color') which _are_ declared, and are used by builtin-commit.c. So maybe we'd like to export it at some point, but it's not declared now, and not used outside of that file, so 'static' it is in this patch.
