Replace unsafe string operations (strcpy, strcat, sprintf, vsprintf) with safe equivalents: 1. The one use of strcpy into an allocated buffer was replaced with strdup. 2. The one use of strcat was replaced with a call to memmove and explicitly setting the NUL terminating byte. 3. sprintf()/vsprintf() calls were replaced with calls to snprintf()/vsnprintf(), respectively. Added a Makefile to build the library as, er, a library and run the test suite. Signed-off-by: Dan Cross <patchdev@fat-dragon.org>
