2708813166 Add and use a constant-time memcmp. 
This change adds CRYPTO_memcmp, which compares two vectors of bytes in
an amount of time that's independent of their contents. It also changes
several MAC compares in the code to use this over the standard memcmp,
which may leak information about the size of a matching prefix.

8d038a08fb The fix for CVE-2012-2110 did not take into account that the 
'len' argument to BUF_MEM_grow and BUF_MEM_grow_clean is an
int in OpenSSL 0.9.8, making it still vulnerable. Fix by
rejecting negative len parameter.

Thanks to the many people who reported this bug and to Tomas Hoger
<thoger@redhat.com> for supplying the fix.
