parse_pathspec: add special flag for max_depth feature
match_pathspec_depth() and tree_entry_interesting() check max_depth field in order to support "git grep --max-depth". The feature activation is tied to "recursive" field, which led to some unwanted activation, e.g. 5c8eeb8 (diff-index: enable recursive pathspec matching in unpack_trees - 2012-01-15). This patch decouples the activation from "recursive" field, puts it in "magic" field instead. This makes sure that only "git grep" can activate this feature. And because parse_pathspec knows when the feature is not used, it does not need to sort pathspec (required for max_depth to work correctly). A small win for non-grep cases. Even though a new magic flag is introduced, no magic syntax is. The magic can be only enabled by parse_pathspec() caller. We might someday want to support ":(maxdepth:10)src." It all depends on actual use cases. max_depth feature cannot be enabled via init_pathspec() anymore. But that's ok because init_pathspec() is on its way to /dev/null.
