PATCH: Improve 32 bit strcat functions with SSE2/SSSE3

[Dmitrieva Liubov]

Hi Urlich,

I fixed overflow bug in 32 bit patch. I've attached small fix that
should be applied after strcat_32 patch.
I added some tests to string/strncat.c for checking overflow bugs as well.

But I have one extra fail on both Core i7 (uses strcat-sse.S) and
Core2 (uses strcat-ssse3.S).

make[4]: *** [/msticlxl27_users/ldmitrie/glibc_32_build/build-i686-linux/string/inl-tester.out]
Error 1
make[3]: *** [string/xtests] Error 2

But I checked master branch for 32 bit (without my 32 bit strcat/strncat).

I have the same problem on both core i7 and core 2 machines.
It seems that there is a problem in the test, not in strncat.

Problem regarding with srncat test.

I can run "./build-i686-linux/string/inl-tester" on my machine with
glibc 2.13 and have the same as for built glibc.
