  treewide: remove use of C++ style comments
  
  C++ style comment ("//") are not specified by the ISO C90 standard and
  thus do not conform to it. While libgit2 aims to conform to C90, we did
  not enforce it until now, which is why quite a lot of these
  non-conforming comments have snuck into our codebase. Do a tree-wide
  conversion of all C++ style comments to the supported C style comments
  to allow us enforcing strict C90 compliance in a later commit.
