merge-recursive: introduce merge_options
This makes it possible to avoid passing the labels of branches as arguments to merge_recursive(), merge_trees() and merge_recursive_generic(). It also takes care of subtree merge, output buffering, verbosity, and rename limits - these were global variables till now in merge-recursive.c. A new function, named init_merge_options(), is introduced as well, it clears the struct merge_info, then initializes with default values, finally updates the default values based on the config and environment variables.
