It's not clear why OpenSSL had a union. The comment says something about sizes
of long, since OpenSSL doesn't use stdint.h. But the variable is treated as a
bunch of uint32_t's, not DES_cblocks.
The key schedule is also always used by iterating or indexing into a uint32_t*,
treating the 16 2-word subkeys as a single uint32_t[32]. Instead, index into
them properly shush any picky tools. The compiler should be able to figure out
what's going on and optimize it appropriately.

The documentation for |BN_CTX_get| states: "Once |BN_CTX_get| has
returned NULL, all future calls will also return NULL until
|BN_CTX_end| is called." Some code takes advantage of that guarantee
by only checking the return value of the last call to |BN_CTX_get| in a
series of calls. That is correct and the most efficient way of doing
it. However, that pattern is inconsistent with most of the other uses
of |BN_CTX_get|. Also, static analysis tools like Coverity cannot
understand that pattern. This commit removes the instances of that
pattern that Coverity complained about when scanning *ring*.

Rather, take a leaf out of Chromium's book and use MSVC's __cpuid and
_xgetbv built-in, with an inline assembly emulated version for other
compilers.
This preserves the behavior of the original assembly with the following
differences:
- CPUs without cpuid aren't support. Chromium's base/cpu.cc doesn't
check, and SSE2 support is part of our baseline; the perlasm code
is always built with OPENSSL_IA32_SSE2.
- The clear_xmm block in cpu-x86-asm.pl is removed. This was used to
clear some XMM-using features if OSXSAVE was set but XCR0 reports the
OS doesn't use XSAVE to store SSE state. This wasn't present in the
x86_64 and seems wrong. Section 13.5.2 of the Intel manual, volume 1,
explicitly says SSE may still be used in this case; the OS may save
that state in FXSAVE instead. A side discussion on upstream's RT#2633
agrees.
- The old code ran some AMD CPUs through the "intel" codepath and some
went straight to "generic" after duplicating some, but not all, logic.
The AMD copy didn't clear some reserved bits and didn't query CPUID 7
for AVX2 support. This is moot since AMD CPUs today don't support
AVX2, but it seems they're expected to in the future?
- Setting bit 10 is dropped. This doesn't appear to be queried anywhere,
was 32-bit only, and seems a remnant of upstream's
14e21f863a3e3278bb8660ea9844e92e52e1f2f7.

In the ancient times, before ex_data and OpenSSL, SSLeay supported a
single app_data slot in various types. Later app_data begat ex_data, and
app_data was replaced by compatibility macros to ex_data index zero.
Today, app_data is still in use, but ex_data never reserved index zero
for app_data. This causes some danger where, if the first ex_data
registration did not use NULL callbacks, the registration's callbacks
would collide with app_data.
Instead, add an option to the types with app_data to reserve index zero.
Also switch SSL_get_ex_data_X509_STORE_CTX_idx to always return zero
rather than allocate a new one. It used to be that you used
X509_STORE_CTX_get_app_data. I only found one consumer that we probably
don't care about, but, to be safe and since it's easy, go with the
conservative option. (Although SSL_get_ex_data_X509_STORE_CTX_idx wasn't
guaranteed to alias app_data, in practice it always did. No consumer
ever calls X509_STORE_CTX_get_ex_new_index.)

Running make_errors.go every time a function is renamed is incredibly

Instead, sample __func__ (__FUNCTION__ in MSVC) in the OPENSSL_PUT_ERROR macro

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.

This is the first structure to be implemented with the new BIGNUM ASN.1
routines. Object reuse in the legacy d2i/i2d functions is implemented by
releasing whatever was in *out before and setting it to the
newly-allocated object. As with the new d2i_SSL_SESSION, this is a
weaker form of object reuse, but should suffice for reasonable callers.
As ECDSA_SIG is more likely to be parsed alone than as part of another
structure (and using CBB is slightly tedious), add convenient functions
which take byte arrays. For consistency with SSL_SESSION, they are named
to/from_bytes. from_bytes, unlike the CBS variant, rejects trailing
data.
Note this changes some test expectations: BER signatures now push an
error code. That they didn't do this was probably a mistake.
