Trim some undocumented symbols from asn1.h.

ASN1_ENCODING can be unexported because all types using it are now
hidden. This does mean external uses of <openssl/asn1t.h> can no longer
use ASN1_SEQUENCE_enc, but there do not seem to be any such uses.

ASN1_TLC and ASN1_TEMPLATE typedefs are only necessary for users of
asn1t.h. I'm hopeful we can do away with ASN1_TLC once I get to
reworking tasn_dec.c. ASN1_TEMPLATE is somewhat stuck, though all
references should be hidden behind macros.

ASN1_generate_* appear to only referenced within the library. Remove the
unused one and move the other to x509/internal.h. (asn1_gen.c is
currently in crypto/x509 rather than crypto/asn1, so I put it in
x509/internal.h to match. I'll leave figuring out that file to later.)

Annoyingly, asn1/internal.h now pulls in asn1t.h, but so it goes.

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.
