The fields of the |bn_blinding_st| are not updated atomically.
Consequently, one field (|A| or |Ai|) might get updated while the
other field (|Ai| or |A|) doesn't get updated, if an error occurs in
the middle of updating. Deal with this by reseting the counter so that
|A| and |Ai| will both get recreated the next time the blinding is
used.
Fix a separate but related issue by resetting the counter to zero after
calling |bn_blinding_create_param| only if |bn_blinding_create_param|
succeeded. Previously, regardless of whether an error occured in
|bn_blinding_create_param|, |b->counter| would get reset to zero. The
consequence of this was that potentially-bad blinding values would get
used 32 times instead of (32 - |b->counter|) times.

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

I messed up a few of these.
ASN1_R_UNSUPPORTED_ALGORITHM doesn't exist. X509_R_UNSUPPORTED_ALGORITHM does
exist as part of X509_PUBKEY_set, but the SPKI parser doesn't emit this. (I
don't mind the legacy code having really weird errors, but since EVP is now
limited to things we like, let's try to keep that clean.) To avoid churn in
Conscrypt, we'll keep defining X509_R_UNSUPPORTED_ALGORITHM, but not actually
do anything with it anymore. Conscrypt was already aware of
EVP_R_UNSUPPORTED_ALGORITHM, so this should be fine. (I don't expect
EVP_R_UNSUPPORTED_ALGORITHM to go away. The SPKI parsers we like live in EVP
now.)
A few other ASN1_R_* values didn't quite match upstream, so make those match
again. Finally, I got some of the rsa_pss.c values wrong. Each of those
corresponds to an (overly specific) RSA_R_* value in upstream. However, those
were gone in BoringSSL since even the initial commit. We placed the RSA <-> EVP
glue in crypto/evp (so crypto/rsa wouldn't depend on crypto/evp) while upstream
placed them in crypto/rsa.
Since no one seemed to notice the loss of RSA_R_INVALID_SALT_LENGTH, let's undo
all the cross-module errors inserted in crypto/rsa. Instead, since that kind of
specificity is not useful, funnel it all into X509_R_INVALID_PSS_PARAMETERS
(formerly EVP_R_INVALID_PSS_PARAMETERS, formerly RSA_R_INVALID_PSS_PARAMETERS).
Reset the error codes for all affected modules.
(That our error code story means error codes are not stable across this kind of
refactoring is kind of a problem. Hopefully this will be the last of it.)

OpenSSL historically made some poor API decisions. Rather than returning a
status enum in SSL_read, etc., these functions must be paired with
SSL_get_error which determines the cause of the last error's failure. This
requires SSL_read communicate with SSL_get_error with some stateful flag,
rwstate.
Further, probably as workarounds for bugs elsewhere, SSL_get_error does not
trust rwstate. Among other quirks, if the error queue is non-empty,
SSL_get_error overrides rwstate and returns a value based on that. This
requires that SSL_read, etc., be called with an empty error queue. (Or we hit
one of the spurious ERR_clear_error calls in the handshake state machine,
likely added as further self-workarounds.)
Since requiring callers consistently clear the error queue everywhere is
unreasonable (crbug.com/567501), clear ERR_clear_error *once* at the entry
point. Until/unless[*] we make SSL_get_error sane, this is the most reasonable
way to get to the point that clearing the error queue on error is optional.
With those in place, the calls in the handshake state machine are no longer
needed. (I suspect all the ERR_clear_system_error calls can also go, but I'll
investigate and think about that separately.)
[*] I'm not even sure it's possible anymore, thanks to the possibility of
BIO_write pushing to the error queue.
