f466cdb5e0 size_t the RSA padding add functions.
The padding check functions will need to tweak their calling conventions
and the constant-time helpers, so leaving those alone for now. These
were the easy ones.

3cb047e56c Decouple PKCS#12 hash lookup from the OID table.
This isn't strictly necessary for Chromium yet, but we already have a
decoupled version of hash algorithm parsing available. For now, don't
export it but eventually we may wish to use it for OCSP.

57e81e666a Name |select_certificate_cb| return values
The |select_certificate_cb| return values are somewhat confusing due
to the fact that they don't match the |cert_cb| ones, despite the
similarities between the two callbacks (they both have "certificate" in
the name! well, sort of).

This also documents the error return value (-1) which was previously
undocumented, and it expands the |SSL_CTX_set_select_certificate_cb|
documentation regarding retrial (by shamelessly copying from
|SSL_CTX_set_ticket_aead_method|).

Also updates other scattered documentation that was missed by previous
changes.

2d05568a7b Fix out-of-memory condition in conf.
conf has the ability to expand variables in config files. Repeatedly doing
this can lead to an exponential increase in the amount of memory required.
This places a limit on the length of a value that can result from an
expansion.

8c6467976c Remove BIGNUM and CBIGNUM crypto/asn1 types.
These too appear to be unused now that the core parsers use CBS. They
also were buggy as they silently ignored sign bits. This removes all
ASN1_PRIMITIVE_FUNCS definitions.  (The code to use them still exists as
we're not ready to diverge on tasn_*. Current thinking is we'll
eventually just ditch the code rather than do so.)

fe36672bf5 Allow users of the |CRYPTO_BUFFER|-based methods to verify certs after the handshake.
Previously, the |CRYPTO_BUFFER|-based methods always rejected
certificate chains because none of the current callbacks is suitable to
use. In the medium-term, we want an async callback for this but, for
now, we would like to get Chromium working. Chromium already installs a
no-op callback (except for the logic that was moved into BoringSSL in
a58baaf9e6) and so this hack will suffice
for Chromium.

ad8f5e1de9 Don't use long for timestamps.
This is the first part to fixing the SSL stack to be 2038-clean.
Internal structures and functions are switched to use OPENSSL_timeval
which, unlike timeval and long, are suitable for timestamps on all
platforms.

It is generally accepted that the year is now sometime after 1970, so
use uint64_t for the timestamps to avoid worrying about serializing
negative numbers in SSL_SESSION.

A follow-up change will fix SSL_CTX_set_current_time_cb to use
OPENSSL_timeval. This will require some coordinating with WebRTC.
DTLSv1_get_timeout is left alone for compatibility and because it stores
time remaining rather than an absolute time.

11c82895d7 Remove support for blocking DTLS timeout handling.
The DTLS stack has two very different APIs for handling timeouts. In
non-blocking mode, timeouts are driven externally by the caller with
DTLSv1_get_timeout. In blocking mode, timeouts are driven by the BIO by
calling a BIO_ctrl with BIO_CTRL_DGRAM_SET_NEXT_TIMEOUT.

The latter is never used by consumers, so remove support for it.
BIO_CTRL_DGRAM_SET_NEXT_TIMEOUT implicitly depends on struct timeval
being used for timestamps, which we would like to remove. Without this,
the only public API which relies on this is the testing-only
SSL_CTX_set_current_time_cb which is BoringSSL-only and we can change at
our leisure.

a57dcfb69c Add new cipherlist-setting APIs that reject nonsense.
The new APIs are SSL_CTX_set_strict_cipher_list() and
SSL_set_strict_cipher_list().  They have two motivations:

First, typos in cipher lists can go undetected for a long time, and
can have surprising consequences when silently ignored.

Second, there is a tendency to use superstition in the construction of
cipher lists, for example by "turning off" things that do not actually
exist.  This leads to the corrosive belief that DEFAULT and ALL ought
not to be trusted.  This belief is false.

5960a90964 Move sid_ctx from SSL/SSL_CTX to CERT.
This reduces us from seven different configuration patterns to six (see
comment #2 of linked bug). I do not believe there is any behavior change
here as SSL_set_SSL_CTX already manually copied the field. It now gives
us a nice invariant: SSL_set_SSL_CTX overrides all and only the
dual-SSL/SSL_CTX options hanging off of CERT.

BUG=123

26e1ff3dfb Remove some unnecessary return values.
I'm not sure why the SSL versions of these functions return int while
the SSL_CTX version returns void. It looks like this dates to
https://boringssl-review.googlesource.com/c/1491/, of which the initial
upload was an SSL_ctrl macro. I guess one of the ints got accidentally
preserved in conversion.

(No existing caller, aside from bssl_shim, checks the result.)

83a321231b Move SCT lists and OCSP responses to CERT.
Recent changes added SSL-level setters to these APIs. Unfortunately,
this has the side effect of breaking SSL_set_SSL_CTX, which is how SNI
is typically handled. SSL_set_SSL_CTX is kind of a weird function in
that it's very sensitive to which of the hodge-podge of config styles is
in use. I previously listed out all the config styles here, but it was
long and unhelpful. (I counted up to 7.)

Of the various SSL_set_SSL_CTX-visible config styles, the sanest seems
to be to move it to CERT. In this case, it's actually quite reasonable
since they're very certificate-related.

Later we may wish to think about whether we can cut down all 7 kinds of
config styles because this is kinda nuts. I'm wondering we should do
CERT => SSL_CONFIG, move everything there, and make that be the same
structure that is dropped post-handshake (supposing the caller has
disavowed SSL_clear and renego). Fruit for later thought. (Note though
that comes with a behavior change for all the existing config.)

16b1b1d4d1 Simplify state and info_callback management.
All the business with rewinding hs->state back or skipping states based
on reuse_message or a skip parameter isn't really worth the trouble for
a debugging callback. With SSL_state no longer exposed, we don't have to
worry about breaking things.

77458a436e Avoid transitioning into SSL_ST_OK and back out.
I doubt this matters, but this seems a little odd. In particular, this
avoids info_callback seeing the SSL_ST_OK once we stop switching
hs->state back and forth.

9e766d7532 Unexport the handshake's internal state.
Code which manages to constrain itself on this will limit our ability to
rework the handshake. I believe, at this point, we only need to expose
one bit of information (there's some code that compares SSL_state to
SSL_ST_OK), if even that.

46db7af2c9 Remove |X509| things from SSL_SESSION.
|SSL_SESSION_from_bytes| now takes an |SSL_CTX*|, from which it uses the
|X509_METHOD| and buffer pool. This is our API so we can do this.

This also requires adding an |SSL_CTX*| argument to |SSL_SESSION_new|
for the same reason. However, |SSL_SESSION_new| already has very few
callers (and none in third-party code that I can see) so I think we can
get away with this.

8df6766d01 Support setting per-connection SCT list
Right now the only way to set an SCT list is the per-context function
SSL_CTX_set_signed_cert_timestamp_list. However this assumes that all the
SSLs generated from a SSL_CTX share the same SCT list, which is wrong.

In order to avoid memory duplication in case SSL_CTX has its own list, a
CRYPTO_BUFFER is used for both SSL_CTX and SSL.
