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
  crypto/x509.

- 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
  pointer.

Thanks to upstream's 411abf2dd3 for the
idea.

conf has the ability to expand variables in config files. Repeatedly doing
this can lead to an exponential increase in the amount of memory required.
This places a limit on the length of a value that can result from an
expansion.

Now that we have the extern "C++" trick, we can just embed them in the
normal headers. Move the EVP_CIPHER_CTX deleter to cipher.h and, in
doing so, take away a little bit of boilerplate in defining deleters.

Unlike the Scoped* types, bssl::UniquePtr is available to C++ users, and
offered for a large variety of types.  The 'extern "C++"' trick is used
to make the C++ bits digestible to C callers that wrap header files in
'extern "C"'.

Apparently OpenSSL's API is made entirely of initialization functions.
Some external libraries like to initialize with OPENSSL_config instead.

With these stubs, cURL should not need any BoringSSL #ifdefs at all,
except for their OCSP #ifdefs (which can switch to the more generally
useful OPENSSL_NO_OCSP) and the workaround for wincrypt.h macro
collisions. That we intentionally leave to the consumer rather than add
a partial hack that makes the build sensitive to include order.

(I'll send them a patch upstream once this cycles in.)

Running make_errors.go every time a function is renamed is incredibly
tedious. Plus we keep getting them wrong.

Instead, sample __func__ (__FUNCTION__ in MSVC) in the OPENSSL_PUT_ERROR macro
and store it alongside file and line number. This doesn't change the format of
ERR_print_errors, however ERR_error_string_n now uses the placeholder
"OPENSSL_internal" rather than an actual function name since that only takes
the uint32_t packed error code as input.

This updates err scripts to not emit the function string table. The
OPENSSL_PUT_ERROR invocations, for now, still include the extra
parameter. That will be removed in a follow-up.

Beyond generally eliminating unnecessary includes, eliminate as many
includes of headers that declare/define particularly error-prone
functionality like strlen, malloc, and free. crypto/err/internal.h was
added to remove the dependency on openssl/thread.h from the public
openssl/err.h header. The include of <stdlib.h> in openssl/mem.h was
retained since it defines OPENSSL_malloc and friends as macros around
the stdlib.h functions. The public x509.h, x509v3.h, and ssl.h headers
were not changed in order to minimize breakage of source compatibility
with external code.

Previously, public headers lived next to the respective code and there
were symlinks from include/openssl to them.

This doesn't work on Windows.

This change moves the headers to live in include/openssl. In cases where
some symlinks pointed to the same header, I've added a file that just
includes the intended target. These cases are all for backwards-compat.
