The original motivation behind the sign/complete split was to avoid
needlessly hashing the input on each pass through the state machine, but
we're payload-based now and, in all cases, the payload is either cheap
to compute or readily available. (Even the hashing worry was probably
unnecessary.)
Tweak ssl_private_key_{sign,decrypt} to automatically call
ssl_private_key_complete as needed and take advantage of this in the
handshake state machines:
- TLS 1.3 signing now computes the payload each pass. The payload is
small and we're already allocating a comparable-sized buffer each
iteration to hold the signature. This shouldn't be a big deal.
- TLS 1.2 decryption code still needs two states due to reading the
message (fixed in new state machine style), but otherwise it just
performs cheap idempotent tasks again. The PSK code is reshuffled to
guarantee the callback is not called twice (though this was impossible
anyway because we don't support RSA_PSK).
- TLS 1.2 CertificateVerify signing is easy as the transcript is readily
available. The buffer is released very slightly later, but it
shouldn't matter.
- TLS 1.2 ServerKeyExchange signing required some reshuffling.
Assembling the ServerKeyExchange parameters is moved to the previous
state. The signing payload has some randoms prepended. This is cheap
enough, but a nuisance in C. Pre-prepend the randoms in
hs->server_params.
With this change, we are *nearly* rid of the A/B => same function
pattern.

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 only place it is used is EC_KEY_{dup,copy} and no one calls that
function on an EC_KEY with ex_data. This aligns with functions like
RSAPublicKey_dup which do not copy ex_data. The logic is also somewhat
subtle in the face of malloc errors (upstream's PR 3323).
In fact, we'd even changed the function pointer signature from upstream,
so BoringSSL-only code is needed to pass this pointer in anyway. (I
haven't switched it to CRYPTO_EX_unused because there are some callers
which pass in an implementation anyway.)
Note, in upstream, the dup hook is also used for SSL_SESSIONs when those
are duplicated (for TLS 1.2 ticket renewal or TLS 1.3 resumption). Our
interpretation is that callers should treat those SSL_SESSIONs
equivalently to newly-established ones. This avoids every consumer
providing a dup hook and simplifies the interface.
(I've gone ahead and removed the TODO(fork). I don't think we'll be able
to change this API. Maybe introduce a new one, but it may not be worth
it? Then again, this API is atrocious... I've never seen anyone use argl
and argp even.)

Instead of a script which generates macros, emit static inlines in
individual header (or C files). This solves a few issues with the
original setup:
- The documentation was off. We match the documentation now.
- The stack macros did not check constness; see some of the fixes in
crypto/x509.
- Type errors did not look like usual type errors.
- Any type which participated in STACK_OF had to be made partially
public. This allows stack types to be defined an internal header or
even an individual file.
- One could not pass sk_FOO_free into something which expects a function
pointer.
