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.)

The OR seems to be correct. %r9d previously contains 1 for a non-Intel
CPU. The next line isolates the XOP bit but *also* preserves that 1.
This figures in later in in line 121 to avoid tagging as Intel. (Most
codepaths in the AMD-specific branch go straight to .Lgeneric, but some
go to .Lintel. This probably could be done more clearly as there's some
complicated code that's subtly different...)

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.

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.

some functions automatically route to the slot while others affect the
