Add fastStrDup to FastMalloc
​https://bugs.webkit.org/show_bug.cgi?id=33937

The new string returned by fastStrDup is obtained with fastMalloc,
and can be freed with fastFree. This makes the memory management
more consistent because we don't need to keep strdup allocated pointers
and free them with free(). Instead we can use fastFree everywhere.
