git-archive: convert archive entries like checkouts do
As noted by Johan Herland, git-archive is a kind of checkout and needs to apply any checkout filters that might be configured. This patch adds the convenience function convert_sha1_file which returns a buffer containing the object's contents, after converting, if necessary (i.e. it's a combination of read_sha1_file and convert_to_working_tree). Direct calls to read_sha1_file in git-archive are then replaced by calls to convert_sha1_file. Since convert_sha1_file expects its path argument to be NUL-terminated -- a convention it inherits from convert_to_working_tree -- the patch also changes the path handling in archive-tar.c to always NUL-terminate the string. It used to solely rely on the len field of struct strbuf before. archive-zip.c already NUL-terminates the path and thus needs no such change.
