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.

when adding duplicates in add_cert_dir.

Add the extension parser in the s_client, ocsp and x509 apps.

This can be used to speed up SRTP with libsrtp, e.g. on TI omap/sitara based devices.

Add the RFC6962 OIDs to the objects table.

Improve CBC decrypt and CTR by ~13/16%, which adds up to ~25/33%
improvement over "pre-Silvermont" version. [Add performance table to
aesni-x86.pl].

When a chain is complete and ends in a trusted root checks are also
performed on the TA and the callback notified with ok==1. For
consistency do the same for chains where the TA is not self signed.

(other processors unaffected).
