When looking for an extension we need to set the last found
position to -1 to properly search all extensions.
PR#3309.
(cherry picked from commit 300b9f0b70)
Treat a zero length passed to ssleay_rand_add a no op: the existing logic
zeroes the md value which is very bad. OpenSSL itself never does this
internally and the actual call doesn't make sense as it would be passing
zero bytes of entropy.
Thanks to Marcus Meissner <meissner@suse.de> for reporting this bug.

Some CMS SignedData structure use a signature algorithm OID such
as SHA1WithRSA instead of the RSA algorithm OID. Workaround this
case by tolerating the signature if we recognise the OID.

Fix for the attack described in the paper "Recovering OpenSSL
ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack"
by Yuval Yarom and Naomi Benger. Details can be obtained from:

Thanks to Yuval Yarom and Naomi Benger for discovering this
flaw and to Yuval Yarom for supplying a fix.

CHANGES
The problem is that OpenSSH calls EVP_Cipher, which is not as
protective as EVP_CipherUpdate. Formally speaking we ought to
do more checks in *_cipher methods, including rejecting
lengths not divisible by block size (unless ciphertext stealing
is in place). But for now I implement check for zero length in
low-level based on precedent.

Add option to set an alternative to the default hmacWithSHA1 PRF
for PKCS#8 private key encryptions. This is used automatically
by PKCS8_encrypt if the nid specified is a PRF.
Add option to pkcs8 utility.
Update docs.
Don't set the fips flags in cipher and digests as the implementations
aren't suitable for FIPS mode and will be redirected to the FIPS module
versions anyway.
Return EVP_CIPH_FLAG_FIPS or EVP_MD_FLAG_FIPS if a FIPS implementation
exists when calling EVP_CIPHER_flags and EVP_MD_flags repectively.
Remove unused FIPS code from e_aes.c: the 1.0.2 branch will never be
used to build a FIPS module.
Windows 8 SDKs complain that GetVersion() is deprecated.
We only use GetVersion like this:
(GetVersion() < 0x80000000)
which checks if the Windows version is NT based. Use a macro check_winnt()
which uses GetVersion() on older SDK versions and true otherwise.
