Move data from .text to .rodata on x86_64

Various constants and strings identifying the authors are currently
misplaced in .text. This change allows using execute-only .text on
platforms that enforce it by default, such as OpenBSD.

Modify x86_64-xlate.pl to replace .rodata with __DATA,__const for macs.
Adapt the nasm/masm path to emit an .rdata segment with alignment of 8.
This last change is not strictly needed but makes things explicit.

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.
