BoringSSL does not generally support this quirk but, in this case, we
didn't make it a fatal error and it's instead a silent omission of
hostname checking. This doesn't affect Chrome but, in case something is
using BoringSSL and using this trick, this change makes it safe.

This is a reland of https://boringssl-review.googlesource.com/2330. I
believe I've now cleared the fallout.
Android's attestion format uses some ludicrously large tag numbers:
https://developer.android.com/training/articles/security-key-attestation.html#certificate_schema
Add support for these in CBS/CBB. The public API does not change for
callers who were using the CBS_ASN1_* constants, but it is no longer the
case that tag representations match their DER encodings for small tag
numbers. When passing tags into CBS/CBB, use CBS_ASN1_* constants. When
working with DER byte arrays (most commonly test vectors), use the
numbers themselves.
Bug: 214
Update-Note: The in-memory representation of CBS/CBB tags changes.
Additionally, we now support tag numbers above 30. I believe I've now
actually cleared the fallout of the former. There is one test in
Chromium and the same test in the internal repository that needs
fixing.

This reverts commit 66801feb17. This
turned out to break a lot more than expected. Hopefully we can reland it
soon, but we need to fix up some consumers first.
Note due to work that went in later, this is not a trivial revert and
should be re-reviewed.

This avoids taking quadratic time to pretty-print certificates with
excessively large integer fields. Very large integers aren't any more
readable in decimal than hexadecimal anyway, and the i2s_* functions
will parse either form.

Rather than adding a new mode to EVP_PKEY_CTX, upstream chose to tie
single-shot signing to EVP_MD_CTX, adding functions which combine
EVP_Digest*Update and EVP_Digest*Final. This adds a weird vestigial
EVP_MD_CTX and makes the signing digest parameter non-uniform, slightly
complicating things. But it means APIs like X509_sign_ctx can work
without modification.
Align with upstream's APIs. This required a bit of fiddling around
evp_test.cc. For consistency and to avoid baking details of parameter
input order, I made it eagerly read all inputs before calling
SetupContext. Otherwise which attributes are present depend a lot on the
shape of the API we use---notably the NO_DEFAULT_DIGEST tests for RSA
switch to failing before consuming an input, which is odd.
(This only matters because we have some tests which expect the operation
to abort the operation early with parameter errors and match against
Error. Those probably should not use FileTest to begin with, but I'll
tease that apart a later time.)
Upstream also named NID_Ed25519 as NID_ED25519, even though the
algorithm is normally stylized as "Ed25519". Switch it to match.

The motiviation is that M2Crypto passes an ASN1_GENERALIZEDTIME to
this function. This is not distinct from ASN1_UTCTIME (both are
asn1_string_st), but ASN1_GENERALIZEDTIME uses a 4-digit year in its
string representation, whereas ASN1_UTCTIME uses a 2-digit year.
ASN1_UTCTIME_print previously did not return an error on such inputs.
So, stricten (?) the function, ensuring that it checks for trailing
data, and rejects values that are invalid for their place. Along the
way, clean it up and add tests.

Most C standard library functions are undefined if passed NULL, even
when the corresponding length is zero. This gives them (and, in turn,
all functions which call them) surprising behavior on empty arrays.
Some compilers will miscompile code due to this rule. See also

Add OPENSSL_memcpy, etc., wrappers which avoid this problem.

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.
