The OPTIONAL prf field is an AlgorithmIdentifier, not an OID.  I messed
this up in the recent rewrite.

Fix the parsing and add a test, produced by commenting out the logic in
OpenSSL to omit the field for hmacWithSHA1. (We don't currently support
any other PBKDF2, or I'd just add a test for that.)

Many of these parameters are constants.

This is a very basic test, but it's something.

This includes examples with both the NULL and empty passwords, thanks to
PKCS#12's password ambiguity.

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"'.

This reverts commit 09feb0f3d9.

(In order to make WebRTC happy this also needs to be reverted.)

This reverts commits:
8d79ed6740
19fdcb5234
8d79ed6740

Because WebRTC (at least) includes our headers in an extern "C" block,
which precludes having any C++ in them.

This change scatters the contents of the two scoped_types.h files into
the headers for each of the areas of the code. The types are now in the
|bssl| namespace.

We currently have the situation where the |tool| and |bssl_shim| code
includes scoped_types.h from crypto/test and ssl/test. That's weird and
shouldn't happen. Also, our C++ consumers might quite like to have
access to the scoped types.

Thus this change moves some of the template code to base.h and puts it
all in a |bssl| namespace to prepare for scattering these types into
their respective headers. In order that all the existing test code be
able to access these types, it's all moved into the same namespace.

This consists mostly of re-adding OpenSSL's implementation of PBKDF2
(very loosely based upon e0d26bb3).  The meat of it, namely
|PKCS5_PBKDF2_HMAC|, was already present, but unused.

In addition, |PKCS8_encrypt| and |PKCS8_decrypt| must be changed to
not perform UCS-2 conversion in the PBES2 case.
