Const-correct the low-level ASN1 i2d functions.

This is completely unchecked for now, as it all goes through tasn_enc.c.
But the only non-const encoders now are X509_NAME, and the functions
that call into it, so we can fix up the ones at the bottom.

I haven't done the macros that use the "name" or "fname" variants. The
set of macros for const are a little weird. But before expanding the
header macros out, I wanted to change the signatures on the macro side
once, so the compiler checks they're expanded correctly.

Update-Note: The type signature of some i2d functions, such as
i2d_ASN1_OCTET_STRING, is now const-correct.

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.
