Convert read_tree{,_recursive} to support struct pathspec

Browse Source 
This patch changes behavior of the two functions. Previously it does
prefix matching only. Now it can also do wildcard matching.

All callers are updated. Some gain wildcard matching (archive,
checkout), others reset pathspec_item.has_wildcard to retain old
behavior (ls-files, ls-tree as they are plumbing).
