* lt/tree-2:
  fetch.c: do not call process_tree() from process_tree().
  tree_entry(): new tree-walking helper function
  adjust to the rebased series by Linus.
  Remove "tree->entries" tree-entry list from tree parser
  Switch "read_tree_recursive()" over to tree-walk functionality
  Make "tree_entry" have a SHA1 instead of a union of object pointers
  Add raw tree buffer info to "struct tree"
  Remove last vestiges of generic tree_entry_list
  Convert fetch.c: process_tree() to raw tree walker
  Convert "mark_tree_uninteresting()" to raw tree walker
  Remove unused "zeropad" entry from tree_list_entry
  fsck-objects: avoid unnecessary tree_entry_list usage
  Remove "tree->entries" tree-entry list from tree parser
  builtin-read-tree.c: avoid tree_entry_list in prime_cache_tree_rec()
  Switch "read_tree_recursive()" over to tree-walk functionality
  Make "tree_entry" have a SHA1 instead of a union of object pointers
  Make "struct tree" contain the pointer to the tree buffer
