af07365b49 Check for overflow when parsing a CBS with d2i_*.
Until we've done away with the d2i_* stack completely, boundaries need
to be mindful of the type mismatch. d2i_* takes a long, not a size_t.

20c373118c Become partially -Wmissing-variable-declarations-clean.
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.

301afaf223 Add a run_tests target to run all tests.
It's very annoying having to remember the right incant every time I want
to switch around between my build, build-release, build-asan, etc.,
output directories.

Unfortunately, this target is pretty unfriendly without CMake 3.2+ (and
Ninja 1.5+). This combination gives a USES_TERMINAL flag to
add_custom_target which uses Ninja's "console" pool, otherwise the
output buffering gets in the way. Ubuntu LTS is still on an older CMake,
so do a version check in the meantime.

CMake also has its own test mechanism (CTest), but this doesn't use it.
It seems to prefer knowing what all the tests are and then tries to do
its own output management and parallelizing and such. We already have
our own runners. all_tests.go could actually be converted tidily, but
generate_build_files.py also needs to read it, and runner.go has very
specific needs.

Naming the target ninja -C build test would be nice, but CTest squats
that name and CMake grumps when you use a reserved name, so I've gone
with run_tests.

15e4deb165 d2i: don't update input pointer on failure
(Imported from upstream's 728bcd59d3d41e152aead0d15acc51a8958536d3.)

Actually this one was reported by us, but the commit message doesn't
mention this.

This is slightly modified from upstream's version to fix some problems
noticed in import. Specifically one of d2i_X509_AUX's success paths is
bust and d2i_PrivateKey still updates on one error path. Resolve the
latter by changing both it and d2i_AutoPrivateKey to explicitly hit the
error path on ret == NULL. This lets us remove the NULL check in
d2i_AutoPrivateKey.

We'll want to report the problems back upstream.

73415b6aa0 Move arm_arch.h and fix up lots of include paths.
arm_arch.h is included from ARM asm files, but lives in crypto/, not
openssl/include/. Since the asm files are often built from a different
location than their position in the source tree, relative include paths
are unlikely to work so, rather than having crypto/ be a de-facto,
second global include path, this change moves arm_arch.h to
include/openssl/.

It also removes entries from many include paths because they should be
needed as relative includes are always based on the locations of the
source file.

aa58513f40 Reserve ex_data index zero for app_data.
In the ancient times, before ex_data and OpenSSL, SSLeay supported a
single app_data slot in various types. Later app_data begat ex_data, and
app_data was replaced by compatibility macros to ex_data index zero.

Today, app_data is still in use, but ex_data never reserved index zero
for app_data. This causes some danger where, if the first ex_data
registration did not use NULL callbacks, the registration's callbacks
would collide with app_data.

Instead, add an option to the types with app_data to reserve index zero.
Also switch SSL_get_ex_data_X509_STORE_CTX_idx to always return zero
rather than allocate a new one. It used to be that you used
X509_STORE_CTX_get_app_data. I only found one consumer that we probably
don't care about, but, to be safe and since it's easy, go with the
conservative option. (Although SSL_get_ex_data_X509_STORE_CTX_idx wasn't
guaranteed to alias app_data, in practice it always did. No consumer
ever calls X509_STORE_CTX_get_ex_new_index.)

Most consumers are also converted. old_rsa_priv_{de,en}code are left
alone for now. Those hooks are passed in parameters which match the old
d2i/i2d pattern (they're only used in d2i_PrivateKey and
i2d_PrivateKey).

Include a test which, among other things, checks that public keys being

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.

6899b19464 Update API to use (char *) for email addresses and hostnames.
Reduces number of silly casts in OpenSSL code and likely most
applications.  Consistent with (char *) for "peername" value from
X509_check_host() and X509_VERIFY_PARAM_get0_peername().

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.

29b186736c Precompute sorted array for error strings.
Previously, error strings were kept in arrays for each subdirectory and
err.c would iterate over them all and insert them at init time to a hash
table.

This means that, even if you have a shared library and lots of processes
using that, each process has ~30KB of private memory from building that
hash table.

This this change, all the error strings are built into a sorted list and
are thus static data. This means that processes can share the error
information and it actually saves binary space because of all the
pointer overhead in the old scheme. Also it saves the time taken
building the hash table at startup.

This removes support for externally-supplied error string data.

deep in crypto/asn1 itself, so I'm going to stop here for now.
