If a ticket callback changes the HMAC digest to SHA512 the existing
sanity checks are not sufficient and an attacker could perform a DoS

The bound on log(2)/3 on the second line is incorrect and has an extra
zero compared to the divisions in the third line. log(2)/3 = 0.10034...
which is bounded by 0.101 and not 0.1001. The divisions actually
correspond to 0.101 which is fine. The third line also dropped a factor
of three.

The actual code appears to be fine. Just the comments are wrong.

Previously, if ct_v1_log_id_from_pkey failed, public_key would be freed by
CTLOG_free at the end of the function, and then again by the caller (who
would assume ownership was not transferred when CTLOG_new returned NULL).

SCT_verify is impossible to call through the public API (SCT_CTX_new() is
not part of the public API), so rename it to SCT_CTX_verify and move it
out of the public API.

SCT_verify_v1 is redundant, since SCT_validate does the same verification
(by calling SCT_verify) and more. The API is less confusing with a single
verification function (SCT_validate).

There was a block of code at the start that used the Camellia cipher. The
original idea behind this was to fill the buffer with non-zero data so that
oversteps can be detected. However this block failed when using no-camellia.
This has been replaced with a RAND_bytes() call.

I also updated the the CTR test section, since it seems to be using a CBC
cipher instead of a CTR cipher.

Original strategy for page-walking was adjust stack pointer and then
touch pages in order. This kind of asks for double-fault, because
if touch fails, then signal will be delivered to frame above adjusted
stack pointer. But touching pages prior adjusting stack pointer would
upset valgrind. As compromise let's adjust stack pointer in pages,
touching top of the stack. This still asks for double-fault, but at
least prevents corruption of neighbour stack if allocation is to
overstep the guard page.

Also omit predict-non-taken hints as they reportedly trigger illegal
instructions in some VM setups.
