unpack-trees: introduce preserve_ignored to unpack_trees_options
Currently, every caller of unpack_trees() that wants to ensure ignored files are overwritten by default needs to: * allocate unpack_trees_options.dir * flip the DIR_SHOW_IGNORED flag in unpack_trees_options.dir->flags * call setup_standard_excludes AND then after the call to unpack_trees() needs to * call dir_clear() * deallocate unpack_trees_options.dir That's a fair amount of boilerplate, and every caller uses identical code. Make this easier by instead introducing a new boolean value where the default value (0) does what we want so that new callers of unpack_trees() automatically get the appropriate behavior. And move all the handling of unpack_trees_options.dir into unpack_trees() itself. While preserve_ignored = 0 is the behavior we feel is the appropriate default, we defer fixing commands to use the appropriate default until a later commit. So, this commit introduces several locations where we manually set preserve_ignored=1. This makes it clear where code paths were previously preserving ignored files when they should not have been; a future commit will flip these to instead use a value of 0 to get the behavior we want.
