This is an extremely important and practical use case. The comment that
state->calls is bounded by the reseed interval isn't quite true. We only
check on entry to the function, which means that it may exceed it by one
call's worth. Switch it to a size_t (which doesn't actually increase
memory because the struct was already padded).

tls_cbc.c is concerned with the variation in where the padding+mac may
end, counted in blocks. Hash blocks are larger than block cipher blocks,
and the hash itself appends some padding. Thus maximal padding off a
64-hash.Size() bytes may not fully stress things.
Just run all inputs modulo the hash block size, so we don't have to
think very hard about the "most difficult" input.

Symptom: When using larger hash functions and short messages,
these six blocks take too much time to be conditionally copied.
Observations:
- SHA-384 consumes more data per iteration, unlike SHA-256.
- The value of `kVarianceBlocks` must depend on the parameters
of the selected hash algorithm.
- Avoid magic constants.
Changes:
- A new formula for the kVarianceBlocks value.
- Stronger test vectors were created in change: 32724.
- The new formula passes these tests.

An EVP_AEAD_CTX used to be a small struct that contained a pointer to
an AEAD-specific context. That involved heap allocating the
AEAD-specific context, which was a problem for users who wanted to setup
and discard these objects quickly.
Instead this change makes EVP_AEAD_CTX large enough to contain the
AEAD-specific context inside itself. The dominant AEAD is AES-GCM, and
that's also the largest. So, in practice, this shouldn't waste too much
memory.

This is consistent with the old behavior of d2i_*_fp and avoids tripping
Conscrypt's unnecessarily fragile error-handling (see
https://github.com/google/conscrypt/pull/552).
Additionally, by source inspection, CPython expects
ASN1_R_HEADER_TOO_LONG on EOF, analogously to PEM_R_NO_START_LINE. Fix
that. The other errors are a bit haphazard in the old implementation
(that code is really hard to follow), so I didn't match it too
carefully. In particular, OpenSSL would report ASN1_R_HEADER_TOO_LONG on
some generic tag parsing, but that is inconsistent with
ASN1_R_HEADER_TOO_LONG being an EOF signal.

This one is a little thorny. All the various block cipher modes
functions and callbacks take a void *key. This allows them to be used
with multiple kinds of block ciphers.
However, the implementations of those callbacks are the normal typed
functions, like AES_encrypt. Those take AES_KEY *key. While, at the ABI
level, this is perfectly fine, C considers this undefined behavior.
If we wish to preserve this genericness, we could either instantiate
multiple versions of these mode functions or create wrappers of
AES_encrypt, etc., that take void *key.
The former means more code and is tedious without C++ templates (maybe
someday...). The latter would not be difficult for a compiler to
optimize out. C mistakenly allowed comparing function pointers for
equality, which means a compiler cannot replace pointers to wrapper
functions with the real thing. (That said, the performance-sensitive
bits already act in chunks, e.g. ctr128_f, so the function call overhead
shouldn't matter.)
But our only 128-bit block cipher is AES anyway, so I just switched
things to use AES_KEY throughout. AES is doing fine, and hopefully we
would have the sense not to pair a hypothetical future block cipher with
so many modes!

BoringSSL depends on the platform's locking APIs to make internal global
state thread-safe, including the PRNG. On some single-threaded embedded
platforms, locking APIs may not exist, so this dependency may be disabled
with a build flag.
Doing so means the consumer promises the library will never be used in any
multi-threaded address space. It causes BoringSSL to be globally thread-unsafe.
Setting it inappropriately will subtly and unpredictably corrupt memory and
leak secret keys.
Unfortunately, folks sometimes misinterpreted OPENSSL_NO_THREADS as skipping an
internal thread pool or disabling an optionally extra-thread-safe mode. This is
not and has never been the case. Rename it to
OPENSSL_NO_THREADS_CORRUPT_MEMORY_AND_LEAK_SECRETS_IF_THREADED to clarify what
this option does.
Update-Note: As a first step, this CL makes both OPENSSL_NO_THREADS and
OPENSSL_NO_THREADS_CORRUPT_MEMORY_AND_LEAK_SECRETS_IF_THREADED work. A later CL
will remove the old name, so migrate callers after or at the same time as
picking up this CL.

Providing a size hint to the allocator is substantially faster,
especially as we already know/need the size for OPENSSL_cleanse.
We provide a weak symbol that falls back to free when a malloc with
sdallocx is not statically linked with BoringSSL.
Alternatives considered:
* Use dlsym(): This is prone to fail on statically linked binaries
without symbols. Additionally, the extra indirection adds call
overhead above and beyond the linker resolved technique we're using.
* Use CMake rules to identify whether sdallocx is available: Once the
library is built, we may link against a variety of malloc
implementations (not all of which may have sdallocx), so we need to
have a fallback when the symbol is unavailable.

We're a far cry from the good old days when we just read from /dev/urandom
without any fuss...
In particular, the threading logic is slightly non-trivial and probably worth
some basic sanity checks. Also write a fork-safety test, and test the
fork-unsafe-buffering path.
The last one is less useful right now, since fork-unsafe-buffering is a no-op
with RDRAND enabled (although we do have an SDE bot...), but it's probably
worth exercising the code in

- In base.h, if BORINGSSL_PREFIX is defined, include
boringssl_prefix_symbols.h
- In all .S files, if BORINGSSL_PREFIX is defined, include
boringssl_prefix_symbols_asm.h
- In base.h, BSSL_NAMESPACE_BEGIN and BSSL_NAMESPACE_END are
defined with appropriate values depending on whether
BORINGSSL_PREFIX is defined; these macros are used in place
of 'namespace bssl {' and '}'
- Add util/make_prefix_headers.go, which takes a list of symbols
and auto-generates the header files mentioned above
- In CMakeLists.txt, if BORINGSSL_PREFIX and BORINGSSL_PREFIX_SYMBOLS
are defined, run util/make_prefix_headers.go to generate header
files
- In various CMakeLists.txt files, add "global_target" that all
targets depend on to give us a place to hook logic that must run
before all other targets (in particular, the header file generation
logic)
- Document this in BUILDING.md, including the fact that it is
the caller's responsibility to provide the symbol list and keep it
up to date
- Note that this scheme has not been tested on Windows, and likely
does not work on it; Windows support will need to be added in a
future commit

Flattening the build seems to have changed the order of actions when
using Make and output directories for perlasm are no longer created
before Perl is run. Additionally, if the output directory doesn't exist,
the perlasm scripts seem to output to stdout instead.

(I'm not sure why this built anywhere, but it did.)
