This patch adds a test for strlen() string.c contains a copy of strlen() from lib/string.c The test first tests the correctness of strlen() by comparing the result with libc strlen(). It tests all cases of alignment. It them tests the duration of an aligned strlen() on a 4 bytes string, on a 16 bytes string and on a 256 bytes string.
