Mercifully, PKCS#12 does not actually make ContentInfo and SafeBag
mutually recursive. The top-level object in a PKCS#12 is a SEQUENCE of
data or encrypted data ContentInfos. Their payloads are a SEQUENCE of
SafeBags (aka SafeContents).
SafeBag is a similar structure to ContentInfo but not identical (it has
attributes in it which we ignore) and actually carries the objects.
There is only recursion if the SafeContents bag type is used, which we
do not process.
This means we don't need to manage recursion depth. This also no longer
allows trailing data after the SEQUENCE and removes the comment about
NSS. The test file still passes, so I'm guessing something else was
going on?

Avoid the X509_ALGOR dependency entirely. The public API is still using
the legacy ASN.1 structures for now, but the conversions are lifted to
the API boundary. Once we resolve that and the OID table dependency,
this module will no longer block unshipping crypto/asn1 and friends from
Chromium.
This changes the calling convention around the two kinds of PBE suites
we support. Each PBE suite provides a free-form encrypt_init function to
setup an EVP_CIPHER_CTX and write the AlgorithmIdentifer to a CBB. It
then provides a common decrypt_init function which sets up an
EVP_CIPHER_CTX given a CBS of the parameter. The common encrypt code
determines how to call which encrypt_init function. The common decrypt
code parses the OID out of the AlgorithmIdentifer and then dispatches to
decrypt_init.
Note this means the encryption codepath no longer involves parsing back
out a AlgorithmIdentifier it just serialized. We don't have a good story
to access an already serialized piece of a CBB in progress (reallocs can
invalidate the pointer in a CBS), so it's easier to cut this step out
entirely.
Also note this renames the "PBES1" schemes from PKCS#5 to PKCS#12. This
makes it easier to get at the PKCS#12 key derivation hooks. Although
PKCS#12 claims these are variants of PKCS#5's PBES1, they're not very
related. PKCS#12 swaps out the key derivation and even defines its own
AlgorithmIdentifier parameter structure (identical to the PKCS#5 PBES1
one). The only thing of PBES1 that survives is the CBC mode padding
scheme, which is deep in EVP_CIPHER for us. (Of course, all this musing
on layering is moot because we don't implement non-PKCS#12 PBES1 schemes
anyway.)
This also moves some of the random API features (default iteration
count, default salt generation) out of the PBE suites and into the
common code.

types with weird constraints on them.
Note that because PKCS#8 has a space for arbitrary attributes, this
parser must admit a hole. I'm assuming for now that we don't need an API
that enforces no attributes and just ignore trailing data in the

CBS_asn1_ber_to_der currently uses heuristics because implicitly-tagged
constructed strings in BER are ambiguous with implicitly-tagged sequences. It's
not possible to convert BER to DER without knowing the schema.
Fortunately, implicitly tagged strings don't appear often so instead split the
job up: CBS_asn1_ber_to_der fixes indefinite-length elements and constructed
strings it can see. Implicitly-tagged strings it leaves uncoverted, but they
will only nest one level down (because BER kindly allows one to nest
constructed strings arbitrarily!).
CBS_get_asn1_implicit_string then performs the final concatenation at parse
time. This isn't much more complex and lets us parse BER more accurately and
also reject a number of mis-encoded values (e.g. constructed INTEGERs are not a
thing) we'd previously let through. The downside is the post-conversion parsing
code must be aware of this limitation of CBS_asn1_ber_to_der. Fortunately,
there's only one implicitly-tagged string in our PKCS#12 code.
(In the category of things that really really don't matter, but I had spare
cycles and the old BER converter is weird.)

It's very annoying having to remember the right incant every time I want
to switch around between my build, build-release, build-asan, etc.,
output directories.
Unfortunately, this target is pretty unfriendly without CMake 3.2+ (and
Ninja 1.5+). This combination gives a USES_TERMINAL flag to
add_custom_target which uses Ninja's "console" pool, otherwise the
output buffering gets in the way. Ubuntu LTS is still on an older CMake,
so do a version check in the meantime.
CMake also has its own test mechanism (CTest), but this doesn't use it.
It seems to prefer knowing what all the tests are and then tries to do
its own output management and parallelizing and such. We already have
our own runners. all_tests.go could actually be converted tidily, but
generate_build_files.py also needs to read it, and runner.go has very
specific needs.
Naming the target ninja -C build test would be nice, but CTest squats
that name and CMake grumps when you use a reserved name, so I've gone
with run_tests.
