86058a256b Tidy up the alert-parsing code.
Align the DTLS and TLS implementations more. s3_pkt.c's version still has
remnants of fragmentable alerts and only one side marks some variables as
const. Also use warning/fatal constants rather than the numbers with comments.

ce9f0177f8 Remove BIO_should_retry checks in DTLS state machines.
These were added in upstream's 7e159e0133d28bec9148446e8f4dd86c0216d819 for
SCTP. As far as I can tell, they were a no-op there too. The corresponding RT
ticket makes no mention of them.

SSL_get_error checks the retry flags of the BIO already. Specifically it checks
BIO_should_read and BIO_should_write, but those two automatically set
BIO_should_retry.

(Minor, but I noticed them idly. One less thing to think about when the state
machines finally unify.)

04c36b5062 Never set RC4_CHAR.
RC4_CHAR is a bit in the x86(-64) CPUID information that switches the
RC4 asm code from using an array of 256 uint32_t's to 256 uint8_t's. It
was originally written for the P4, where the uint8_t style was faster.

(On modern chips, setting RC4_CHAR took RC4-MD5 from 458 to 304 MB/s.
Although I wonder whether, on a server with many connections, using less
cache wouldn't be better.)

However, I'm not too worried about a slowdown of RC4 on P4 systems these
days (the last new P4 chip was released nine years ago) and I want the
code to be simplier.

Also, RC4_CHAR was set when the CPUID family was 15, but Intel actually
lists 15 as a special code meaning "also check the extended family
bits", which the asm didn't do.

The RC4_CHAR support remains in the RC4 asm code to avoid drift with
upstream.

97999919bb Hide all asm symbols.
We are leaking asm symbols in Android builds because the asm code isn't
affected by -fvisibility=hidden. This change hides all asm symbols.

This assumes that no asm symbols are public API and that should be true.
Some points to note:

In crypto/rc4/asm/rc4-md5-x86_64.pl there are |RC4_set_key| and
|RC4_options| functions which aren't getting marked as hidden. That's
because those functions aren't actually ever generated. (I'm just trying
to minimise drift with upstream here.)

In crypto/rc4/asm/rc4-x86_64.pl there's |RC4_options| which is "public"
API, except that we've never had it in the header files. So I've just
deleted it. Since we have an internal caller, we'll probably have to put
it back in the future, but it can just be done in rc4.c to save
problems.

16e38b2b8f Mark OPENSSL_armcap_P as hidden in ARM asm.
This is an import from ARM. Without this, one of the Android builds of
BoringSSL was failing with:
  (sha512-armv4.o): requires unsupported dynamic reloc R_ARM_REL32; recompile with -fPIC

This is (I believe) a very misleading error message. The R_ARM_REL32
relocation type is the correct type for position independent code. But
unless the target symbol is hidden then the linker doesn't know that
it's not going to be overridden by a different ELF module.

Chromium probably gets away with this because of different default
compiler flags than Android.

dd1ca99da4 Remove X509_get_pubkey_parameters.
It's never called in outside code. This too seems to be a remnant of the DSA
PKIX optional parameter stuff. This is confirmed both by a removed comment and
by the brief documentation at http://www.umich.edu/~x509/ssleay/x509_pkey.html

RFC 5480 does not allow ECDSA keys to be missing parameters, so this logic is
incorrect for ECDSA anyway.  It was also failing to check
EVP_PKEY_copy_parameters' return value. And that logic looks pretty suspect if
you have a chain made up multiple certificate types.

310db06b79 Don't EVP_PKEY_copy_parameters when configuring cert and key.
I believe this is a remnant of DSA. The logic strangely fails to check for
failure and then goes out of its way to ERR_clear_error. I believe this is so
that keys that are missing parameters silently move on. This dates to
upstream's dfeab0689f69c0b4bd3480ffd37a9cacc2f17d9c, which is SSLeay 0.9.1b. At
that time, EVP_PKEY_copy_parameters only did anything for DSA. (Now it only
does anything for ECDSA.)

My read is that this comes from DSA in PKIX's "optional domain parameters"
craziness. RFC 3279 says:

   If the DSA domain parameters are omitted from the SubjectPublicKeyInfo
   AlgorithmIdentifier and the CA signed the subject certificate using a
   signature algorithm other than DSA, then the subject's DSA domain parameters
   are distributed by other means.

This was probably part of some weird thing where, if your certificate is
missing parameters, the server would know what to use based on the private key.

(Also this was making the malloc tests unhappy.)

Found while diagnosing some crashes and hangs in the malloc tests. This (and

quietly, even without valgrind. DTLS silently ignores some malloc failures
(confusion with silently dropping bad packets) which then translate to hangs.

a54e2e85ee Remove server-side HelloVerifyRequest support.
I found no users of this. We can restore it if needbe, but I don't expect
anyone to find it useful in its current form. The API is suspect for the same
reasons DTLSv1_listen was. An SSL object is stateful and assumes you already
have the endpoint separated out.

If we ever need it, server-side HelloVerifyRequest and DTLSv1_listen should be
implemented by a separate stateless listener that statelessly handles
cookieless ClientHello + HelloVerifyRequest. Once a ClientHello with a valid
cookie comes in, it sets up a stateful SSL object and passes control along to
that.

3673be7cb6 Fix standalone build on Win64.
Win64 fires significantly more warnings than Win32. Also some recent
changes made it grumpy.

(We might want to reconsider enabling all of MSVC's warnings. Given the sorts
of warnings some of these are, I'm not sure MSVC's version of -Wall -Werror is
actually tenable. Plus, diverging from the Chromium build, especially before
the bots are ready, is going to break pretty readily.)

This saves about 6-7k of error data.

96396b3aaa Fix cross-module errors.
Some files in crypto/x509 were moved from crypto/asn1, so they emit errors from
another module. Fix make_errors.go to account for this: cross module errors
must use the foreign module as the first argument to OPENSSL_PUT_ERROR. Both
the function code and the error code should be declared in the foreign module.

Update make_errors.go to ignore cross-module error lines when deciding which
function tokens to emit.

32f1650658 Split error string data across multiple lines.
Otherwise running git grep for a single function gives a ton of noise.
