@param repo The repository containing the path.
@param flags A combination of GIT_ATTR_CHECK... flags.
@param path Path inside the repo to check attributes. This does not have
to exist, but if it does not, then it will be treated as a
plain file (i.e. not a directory).
@param callback Function to invoke on each attribute name and value. The
value may be NULL is the attribute is explicitly set to
UNSPECIFIED using the '!' sign. Callback will be invoked
only once per attribute name, even if there are multiple
rules for a given file. The highest priority rule will be
used. Return a non-zero value from this to stop looping.
@param payload Passed on as extra parameter to callback function.
@return 0 on success, GIT_EUSER on non-zero callback, or error code
Loop over all the git attributes for a path.
