FORTIFY_SOURCE: strcat / strncat optimize
__strcat_chk and __strncat_chk are slightly inefficient,
because they end up traversing over the same memory region
two times.
This change optimizes __strcat_chk / __strncat_chk so they
only access the memory once. Although I haven't benchmarked these
changes, it should improve the performance of these functions.
__strlen_chk - expose this function, even if -D_FORTIFY_SOURCE
isn't defined. This is needed to compile libc itself without
-D_FORTIFY_SOURCE.
