fd0325bd98 fix unittests.
7e6ce1a3c5 fixed abort() to raise
SIGABRT rather than causing SIGSEGV. However, the unittests were
not updated.

Fix unittests.

cf870199d5 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.

Upgrade sprintf to fortify_source level 2, to catch
additional security bugs.

1aae9bd170 strncpy: implement _FORTIFY_SOURCE=2
Add support for fortify source level 2 to strncpy.
This will enable detection of more areas where strncpy
is used inappropriately. For example, this would have detected
bug 8727221.

Move the fortify_source tests out of string_test.cpp, and
put it into fortify1_test.cpp.

Create a new fortify2_test.cpp file, which copies all
the tests in fortify1_test.cpp, and adds fortify_source level
2 specific tests.
