+Subject: [PATCH] lib: add glibc style strchrnul() variant
+
+The strchrnul() variant helpfully returns a the end of the string
+instead of a NULL if the requested character is not found. This can
+simplify string parsing code since it doesn't need to expicitly check
+for a NULL return. If a valid string pointer is passed in, then a valid
+null terminated string will always come back out.
