Firstly, new_refinfo() which is used to allocate memory for a new refinfo structure and copy the objectname, refname and flag to it. Secondly, match_name_as_path() which when given an array of patterns and the refname checks if the refname matches any of the patterns given while the pattern is a pathname, also supports wildcard characters. This is a preperatory patch for restructuring 'for-each-ref' and eventually moving most of it to 'ref-filter' to provide the functionality to similar commands via public API's.
