convert.c: remove input_crlf_action() 

Integrate the code of input_crlf_action() into convert_attrs(),
so that ca.crlf_action is always valid after calling convert_attrs().
Keep a copy of crlf_action in attr_action, this is needed for
get_convert_attr_ascii().

Remove eol_attr from struct conv_attrs, as it is now used temporally.
