allow to use CLASS() for struct filename *

Browse source

Not all users match that model, but most of them do.  By the end of
the series we'll be left with very few irregular ones...

Added:
CLASS(filename, name)(user_path) =>
	getname(user_path)
CLASS(filename_kernel, name)(string) =>
	getname_kernel(string)
CLASS(filename_flags, name)(user_path, flags) =>
	getname_flags(user_path, flags)
CLASS(filename_uflags, name)(user_path, flags) =>
	getname_uflags(user_path, flags)
CLASS(filename_maybe_null, name)(user_path, flags) =>
	getname_maybe_null(user_path, flags)
all with putname() as destructor.

"flags" in filename_flags is in LOOKUP_... space, only LOOKUP_EMPTY matters.
"flags" in filename_uflags and filename_maybe_null is in AT_...... space,
and only AT_EMPTY_PATH matters.

filename_flags conventions might be worth reconsidering later (it might or
might not be better off with boolean instead)
