2b2d66d409 Remove string.h from base.h.
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.

c20febe177 Add EVP_PKEY_supports_digest.
This is intended for TLS client auth with Windows CAPI- and CNG-backed keys
which implement sign over sign_raw and do not support all hash functions. Only
plumbed through RSA for now.

6bc658d2e3 Split off private_transform function in RSA.
This change extracts two, common parts of RSA_decrypt and RSA_sign into
a function called |private_transform|. It also allows this to be
overridden in a method, which is convenient for opaque keys that only
expose the raw RSA transform as it means that the padding code from
BoringSSL can be easily reimplemented.

One significant change here is that short RSA ciphertexts will no longer
be accepted. I think this is correct and OpenSSL has a comment about PGP
mistakenly stripping leading zeros. However, these is the possibility
that it could break something.

05b7377065 Add RSA_check_key function.
This is function that is available in OpenSSL too. Here it only returns
zero or one and doesn't do expensive primality checks on p and q.

ecc0ce7e67 Introduce EVP_PKEY_is_opaque to replace RSA_METHOD_FLAG_NO_CHECK.
Custom RSA and ECDSA keys may not expose the key material. Plumb and "opaque"
bit out of the *_METHOD up to EVP_PKEY. Query that in ssl_rsa.c to skip the
sanity checks for certificate and key matching.

925fee36e1 Add a size hook to RSA_METHOD.
This is to avoid having to copy over the RSA modulus in all of Chromium's
platform-specific keys.

409766d218 Add function to recover RSA CRT params.
Some RSA private keys are specified with only n, e and d. Although we
can use these keys directly, it's nice to have a uniform representation
that includes the precomputed CRT values. This change adds a function
that can recover the primes from a minimal private key of that form.

95c29f3cd1 Inital import.
Initial fork from f2d678e6e89b6508147086610e985d4e8416e867 (1.0.2 beta).

(This change contains substantial changes from the original and
effectively starts a new history.)
