Remove X509_REQ_set_extension_nids and document related functions.

PKCS#10 CSRs don't contain extensions but attributes, which are kind of
like extensions, but defined separately. There is an attribute type from
PKCS#9 to embed a list of X.509 extensions inside an attribute, as well
as a Microsoft variant.

X509_REQ_set_extension_nids allowed callers globally reconfigure the set
of attributes recognized as aliases of this extensions attribute.  This
is not used by anyone and not thread-safe. Remove it and only support
the two default attribute types.

From there, document the remaining functions.

Update-Note: This removes a pair of unused functions.

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.
