kconfig: introduce specialized printer
Make conf_write_symbol() grammar agnostic to be able to use it from different code path. These path pass a printer callback which will print a symbol's name and its value in different format. conf_write_symbol()'s job become mostly only to prepare a string for the printer. This avoid to have to pass specialized flag to generic functions Signed-off-by: Arnaud Lacombe <lacombar@gmail.com> [mmarek: rebased on top of de12518 (kconfig: autogenerated config_is_xxx macro)] Signed-off-by: Michal Marek <mmarek@suse.cz>
