Convert stack.h to use inline functions.

Instead of a script which generates macros, emit static inlines in
individual header (or C files). This solves a few issues with the
original setup:

- The documentation was off. We match the documentation now.

- The stack macros did not check constness; see some of the fixes in

- Type errors did not look like usual type errors.

- Any type which participated in STACK_OF had to be made partially
  public. This allows stack types to be defined an internal header or
  even an individual file.

- One could not pass sk_FOO_free into something which expects a function

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.
