Having a different API for this case than upstream is more trouble than is
worth it. This is sad since the new API avoids incomplete EC_GROUPs at least,
but I don't believe supporting this pair of functions will be significantly
more complex than supporting EC_GROUP_new_arbitrary even when we have static
EC_GROUPs.
For now, keep both sets of APIs around, but we'll be able to remove the scar
tissue once Conscrypt's complex dependencies are resolved.
Make the restored EC_GROUP_set_generator somewhat simpler than before by
removing the ability to call it multiple times and with some parameters set to
NULL. Keep the test.

Functions which lose object reuse and need auditing:
- d2i_ECParameters
- d2i_ECPrivateKey
This adds a handful of bytestring-based APIs to handle EC key
serialization. Deprecate all the old serialization APIs. Notes:
- An EC_KEY has additional state that controls its encoding, enc_flags
and conv_form. conv_form is left alone, but enc_flags in the new API
is an explicit parameter.
- d2i_ECPrivateKey interpreted its T** argument unlike nearly every
other d2i function. This is an explicit EC_GROUP parameter in the new
function.
- The new specified curve code is much stricter and should parse enough
to uniquely identify the curve.
- I've not bothered with a new version of i2d_ECParameters. It just
writes an OID. This may change later when decoupling from the giant
OID table.
- Likewise, I've not bothered with new APIs for the public key since the
EC_POINT APIs should suffice.
- Previously, d2i_ECPrivateKey would not call EC_KEY_check_key and it
was possible for the imported public and private key to mismatch. It
now calls it.

∙ Add a few, no-op #defines

This is only for Conscrypt which always calls the pair in succession. (Indeed
it wouldn't make any sense to not call it.) Remove those two APIs and replace
with a single merged API. This way incomplete EC_GROUPs never escape outside

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.

Perhaps in time we can remove this support, but not yet.

This change marks public symbols as dynamically exported. This means
that it becomes viable to build a shared library of libcrypto and libssl
with -fvisibility=hidden.
On Windows, one not only needs to mark functions for export in a
component, but also for import when using them from a different
component. Because of this we have to build with
|BORINGSSL_IMPLEMENTATION| defined when building the code. Other
components, when including our headers, won't have that defined and then
the |OPENSSL_EXPORT| tag becomes an import tag instead. See the #defines
in base.h
In the asm code, symbols are now hidden by default and those that need
to be exported are wrapped by a C function.
