Upstream have added |EVP_PKEY_up_ref|, but their version returns an int.
Having this function with a different signature like that is dangerous
so this change aligns BoringSSL with upstream. Users of this function in
Chromium and internally should already have been updated.

A lot of consumers of obj.h only want the NID values. Others didn't need
it at all. This also removes some OBJ_nid2sn and OBJ_nid2ln calls in EVP
error paths which isn't worth pulling a large table in for.

It's never used. It's not clear why one would want such a thing.
EVP_PKEY_CTX has no way for callers to register callbacks, which means
there shouldn't be a way for the library to present you an EVP_PKEY_CTX
out-of-context. (Whereas app_data/ex_data makes sense on SSL because of
its numerous callbacks or RSA because of RSA_METHOD.)

foo_init hooks are never implemented. Even upstream never uses them. The

node.js is, effectively, another bindings library. However, it's better
written than most and, with these changes, only a couple of tiny fixes
are needed in node.js. Some of these changes are a little depressing
however so we'll need to push node.js to use APIs where possible.
Changes:
∙ Support verify_recover. This is very obscure and the motivation
appears to be https://github.com/nodejs/node/issues/477 – where it's
not clear that anyone understands what it means :(
∙ Add a few, no-op #defines
∙ Add some members to |SSL_CTX| and |SSL| – node.js needs to not
reach into these structs in the future.
∙ Add EC_get_builtin_curves.
∙ Add EVP_[CIPHER|MD]_do_all_sorted – these functions are limited to
decrepit.

There's a few things that will be kind of a nuisance and possibly not worth it
(crypto/asn1 dumps a lot of undeclared things, etc.). But it caught some
mistakes. Even without the warning, making sure to include the externs before
defining a function helps catch type mismatches.

This removes EVP_PKEY_HMAC and all the support code around it. EVP_MD requires
a lot of extra glue to support HMAC. This lets us prune it all away.
As a bonus, it removes a (minor) dependency from EVP to the legacy ASN.1 stack.

No code within BoringSSL or Google (grep for EVP_PKEY_CTX_(ctrl|get|set)) is
sensitive to the various failure cases. Normalize it all to 0/1 for simplicity.
This does carry a slight risk: any new ctrl hooks we import from upstream that,
like EVP_PKEY_CTX_get_rsa_oaep_md, return something other than success/failure
cannot be called directly via EVP_PKEY_CTX_ctrl. They instead need to
internally be routed through a struct like CBS and only called through the
wrappers. To that end, unexport EVP_PKEY_CTX_ctrl and require that callers use
the wrappers. No code in Google uses it directly and, if need be, switching to
the wrapper would be an incredibly upstreamable patch.

Including string.h in base.h causes any file that includes a BoringSSL
header to include string.h. Generally this wouldn't be a problem,
although string.h might slow down the compile if it wasn't otherwise
needed. However, it also causes problems for ipsec-tools in Android
because OpenSSL didn't have this behaviour.
This change removes string.h from base.h and, instead, adds it to each
.c file that requires it.

This commit fixes a number of crashes caused by malloc failures. They
were found using the -malloc-test=0 option to runner.go which runs tests
many times, causing a different allocation call to fail in each case.
(This test only works on Linux and only looks for crashes caused by
allocation failures, not memory leaks or other errors.)
This is not the complete set of crashes! More can be found by collecting
core dumps from running with -malloc-test=0.

Where possible, functions should return one for success and zero for
error. The use of additional negative values to indicate an error is,
itself, error prone.
This change fixes many EVP functions to remove the possibility of
negative return values. Existing code that is testing for <= 0 will
continue to function, although there is the possibility that some code
was differentiating between negative values (error) and zero (invalid
signature) for the verify functions and will now show the wrong error
message.

Converting check_autoarg from a macro to a function lost the behavior. Instead,
just move the logic into p_rsa.c which was the only EVP_PKEY implementation
that even needed the flag.
Also document this behavior on each of the functions. Make note of the out =
NULL case only returning the maximum output size, and not necessarily the
actual size.
For testing, update example_sign to determine the signature size using the NULL
behavior rather than querying the RSA key.
