Turn unpack_trees_options.msgs into an array + enum
The list of error messages was introduced as a structure, but an array indexed over an enum is more flexible, since it allows one to store a type of error message (index in the array) in a variable. This change needs to rename would_lose_untracked -> would_lose_untracked_file to avoid a clash with the function would_lose_untracked in merge-recursive.c.
