[PATCH 1/5] Rename functions in preparation for get_pathspec() restructure

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

This renames:

 - get_pathspec()         to get_pathspec_old()
 - match_pathspec()       to match_pathspec_old()
 - match_pathspec_depth() to match_pathspec()

The name get_pathspec() will be used for a new function which produces
struct pathspec directly.

Both get_pathspec implementations will co-exist for a while until
everything is converted to get_pathspec(). By that point, both
match_pathspec_old() and get_pathspec_old() would be removed.

Because two get_pathspec impl must provide the same functionality, the
new get_pathspec() can't (or shouldn't) implement any magic other than
'top' and 'icase' already supported by get_pathspec_old().
