Slightly simplify and deprecate i2d_{Public,Private}Key.

There are all the type-specific serializations rather than something
tagged with a type. i2d_PrivateKey's PKCS#8 codepath was unreachable
because every EVP_PKEY type has an old_priv_encode function.

To prune EVP_PKEY_ASN1_METHOD further, replace i2d_PrivateKey into a
switch case so we don't need to keep old_priv_encode around. This cuts
down on a case of outside modules reaching into crypto/evp method

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.
