[PATCH 02/18] Export outnl and indent functions for modules

[Zdenek Kabelac <zkabelac@xxxxxxxxxx>]

Exporting functions out_inc_indent(), out_dec_indent() for creating
indented metadata lines. Macro outnl() is using out_newline()
instead of direct f->fn() that required the visibility of internal
struct formatter.
