Remove -2 return value from X509*_get_*_by_NID.

X509*_get_*_by_NID return -1 if the extension was not found, but -2 if
the NID was invalid. Looking through callers, many check index != -1,
rather than index < 0. That means, in theory, they'll do the wrong thing
in some cases.

Realistically, this case is impossible: most callers pass in a constant.
Even in those that don't, NIDs are a local enum, not standard constants.
That means hitting this path is almost certainly a programmer error. No
need to complicate the calling convention for it.

Update-Note: The return value convention of some functions was
simplified. This is not expected to affect any callers.

BoringSSL

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.

Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.

Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.

BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.

Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
