Commit 6467de5 added some timing resistance to ECC shared secret
agreement. It involved adding an RNG object to the ecc keys so
a random z value can be added to the mix. The older FIPS release
has ECC outside the boundary, so it uses the new ECC code. FIPSv2
has ECC inside the boundary, but all the TLS code checks for that
version of FIPS and leaves out the calls to the new functions as
it is using an older version of ecc.c. FIPS Ready uses the latest
version of ecc.c but compiles as FIPSv2. So, the code outside of
the crypto layer is treating ECC as FIPSv2 and not calling the new
functions, but the crypto layer assumes the RNG should be present,
and errs out on testing.
1. Added a separate option for FIPS Ready to the enable-fips
configure option. `--enable-fips=ready`. It will treat FIPS
Ready as the next kind of FIPS release. FIPS Ready will be
treated like FIPS v3 in the build.
2. Changed the C preprocessor checks for FIPS version 2 to be
checks for not version 2, with respect to ECC Timing Resistance
and FIPS builds.
An RNG is required for shared secret calculation now.
Use wc_ecc_set_rng() to set an RNG against the ECC object.
ECC verification does not need timing resistance and does not randomize
z ordinates.
- Add X509_get0_notBefore and X509_get0_notAfter
- Implement EVP_PKEY_get0_DSA and DSA_bits
- OpenSSL_version now prints "wolfSSL $VERSION"
- Remove define guards in `wolfSSL_internal_get_version` as all protocols are defined regardless in `wolfssl/internal.h`and this function just returns the string description of the protocol
- Tag checking in AES-GCM is done in Final call
- Reset `WOLFSSL_EVP_CIPHER_CTX` structure after Final call
- Don't zero `ctx->authTag` struct in Init call so that user can get the AES-GCM tag using `EVP_CIPHER_CTX_ctrl(ctx, EVP_CTRL_GCM_GET_TAG, AES_BLOCK_SIZE, tag)`
- `ctx->authTag` is only zeroed before authenticated, non-confidential data Update call since this means we are entering a new Udate-Final cycle. This doesn't need to be done in the decrypt case since the tag should be supplied by the user before the final call using `EVP_CIPHER_CTX_ctrl(ctx, EVP_CTRL_GCM_SET_TAG, AES_BLOCK_SIZE, tag)`
1. In `wolfSSL_d2i_DHparams()`, when setting the internal key on a
WOLFSSL_KEY, set the flag inSet.
2. Not a leak, but in `wolfSSL_EVP_PKEY_set1_DH()`, only allocate one
buffer to store the flat key. Saves an alloc, memcpy, and free.

- Added `wc_ecc_get_generator` as a way to get the generator point of a curve
- Added `wc_ecc_export_point_der_ex` to export an ECC point in compressed or uncompressed format with one API
- Added `wc_ecc_export_point_der_compressed` to export a point in an `ecc_point` structure in compressed DER format
- Added 'wc_RsaSSL_Verify_ex` which adds the option to choose a padding type
- Added `wc_RsaPad_ex` and `wc_RsaUnPad_ex` to `rsa.h` as `WOLFSSL_LOCAL` functions
- `CopyDecodedToX509` now fills `x509->key` and `x509->algor` when populating x509
- `wolfSSL_EVP_CipherInit` now uses `wc_AesGcmSetExtIV` to set the IV so that it is copied to `ctx->iv` by `wolfSSL_StoreExternalIV`
- Added error checking to `wolfSSL_EVP_PKEY_get_der`
- `wolfSSL_X509_ALGOR_get0` now attempts to return something in all parameters
- Refactored `wolfSSL_EC_KEY_new` to use `*_new` functions when available
- Added `setupPoint` to set the internal point if not yet set
- Always set external point in `wolfSSL_ECPoint_d2i`
- Added compressed point support to `wolfSSL_EC_POINT_point2oct`
- Fix `wolfSSL_EC_POINT_mul` so that it will calculate the full `generator * n + q * m` then OpenSSL does

Added PRIVATE_D version of rsa private key operation for SP
implementation for specific platforms.
WC_NO_RNG results in warnings when RNG calls don't do anything.
Added ifdef checks for variables not used otherwise.
Remove superfluous if statements like when checking ret == 0.
Change names of globals that are generic and are used locally before
global definition.
Remove definition of variable len that isn't used except as a
replacement for sz which is parameter.
Don't subtract two variables when one has just been assigned the value
of the other.
Fix shifting of signed value.
Fix parameter checking in aes.c and des3.c for platform specific code.
