This patch add the for_each_line macro based on a strline_r() function (similar to strtok_r()), that is also part of this patch. This strline_r() function is tolerant with respect to line endings, it supports CR-only, CRLF, and LF-only and any combinations thereof (note that a CRLF is always detected as a single line break). Similar to for_each_non_empty_line (the former for_each_line) where the 'save' pointer needed to be initialised by a call to strtok_r(), the new for_each_line macro expects, that the 'save' pointer has been initialised by a call to strline_r(). Also note, that for_each_line/strline_r and for_each_non_empty_line/strtok_r may use the 'save' pointer differently, so calls to them can not be mixed. Sponsored-by: On-Waves ehf
