This imports the EVP_PKEY test data of upstream's evptests.txt, but
modified to fit our test framework and with a new test driver. The
remainder of the test data will be imported separately into aead_test
and cipher_test.
Some minor changes to the test format were made to account for test
framework differences. One test has different results since we don't
support RSA signatures with omitted (rather than NULL) parameters.
Otherwise, the biggest difference in test format is that the ad-hoc
result strings are replaced with checking ERR_peek_error.

This adds a file-based test framework to crypto/test. It knows how to
parse formats similar to either upstream's evp_test and our aead_test.
hmac_test has been converted to that with tests from upstream's
evp_test. Upstream tests it against the deprecated EVP_PKEY_HMAC API,
which will be tested by running evp_test against the same input file, to
avoid having to duplicate the test vectors. hmac_test runs those same
inputs against the supported HMAC_CTX APIs.

There's no good reason to do this, and it doesn't work; HMAC checks the length
of the key and runs it through the hash function if too long. The reuse occurs
after this check.
This allows us to shave 132 bytes off HMAC_CTX as this was the only reason it
ever stored the original key. It also slightly simplifies HMAC_Init_ex's
logic.

We've already initialized the context, HMAC_Init has questionable behavior
around NULL keys, and this avoids a size_t truncation.

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.

The special-case in HMAC is no longer needed. Test that HMAC_CTX is initialized

In an attempt to assign a zero-length HMAC key, consumers might
incorrectly call:
HMAC_Init_ex(key=NULL, key_len=0)
This does not work as expected since |key==NULL| has special semantics.
This bug may consequently result in uninitialized memory being used for
the HMAC key data.
This workaround doesn't fix all the problems associated with this
pattern, however by defaulting to a zero key the results are more
predictable than before.

HMAC_CTX_copy's documentation is off. It actually follows the old copy
functions which call FOO_init on dest first. Notably this means that they leak
memory if dest is currently in use.
Add HMAC_CTX_copy_ex as an analog of EVP_MD_CTX_copy and deprecate
HMAC_CTX_copy. (EVP_CIPHER_CTX_copy, in contrast, was correct from the start.)

The expectation when calling HMAC with key=NULL and keylen=0 is to compute
HMAC on the provided data with a key of length 0 instead of using the
"previous" key, which in the case of HMAC() is whatever bytes happen to be
left on the stack when the HMAC_CTX struct is allocated.

Chromium does not like static initializers, and the CPU logic uses one to
initialize CPU bits. However, the crypto library lacks an explicit
initialization function, which could complicate (no compile-time errors)
porting existing code which uses crypto/, but not ssl/.
Add an explicit CRYPTO_library_init function, but make it a no-op by default.
It only does anything (and is required) if building with
BORINGSSL_NO_STATIC_INITIALIZER.

Previously, public headers lived next to the respective code and there
were symlinks from include/openssl to them.
This doesn't work on Windows.
This change moves the headers to live in include/openssl. In cases where
some symlinks pointed to the same header, I've added a file that just
includes the intended target. These cases are all for backwards-compat.
