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.
* Fix for key gen macro name in benchmark.c
* Fix for possible RSA fall-through warning.
* Fix for building `WOLFSSL_STM32_PKA` without `HAVE_ECC`.
* Added option to build RSA keygen without the DER to PEM using `WOLFSSL_NO_DER_TO_PEM`.
* Added options.h includes for test.c and benchmark.c.
* Added printf warning on the math size mismatch in test.c.
* Added support for benchmarking larger sizes.
* TLS benchmarks for HiFive unleashed.
Feature: Added support for testing date override at build-time using `TEST_BEFORE_DATE`.
```
./examples/server/server -H overrideDateErr -A ./certs/ca-cert.pem -k ./certs/server-key.pem -c ./certs/intermediate/server-chain.pem &
./examples/client/client -D -A ./certs/ca-cert.pem -k ./certs/client-key.pem -c ./certs/intermediate/client-chain.pem
```
1. Rearrange the deprecation cryptodev option so it doesn't overwrite the cryptocb option, and so it doesn't break its case in the build-test.
2. Fix the content length in the sample HTTP used by the example server.
3. Disable OCSP stapling in the example server if RSA is disabled.
4. Fix a variable in asn.c that was declared in the middle of its scope.
5. Retag the xmalloc, xrealloc, xfree functions used in the memory test as WOLFSSL_API like all the other allocators, instead of extern.
1. The combination enable-all and disable-rsa breaks some of the
testing. Added the NO_RSA guards as appropriate.
2. Disabled the OCSP stapling and CRL tests when RSA is disabled as they
use test certificates with RSA keys.
Added an API for enabling the Trusted CA Key Indication extension from
RFC6066 section 6. If the server doesn't have a match for the client,
the client will abandon the session.
Fix wc_ecc_fp_free() to be called when using HAVE_STACK_SIZE.
Increase size of replyin client.c so all HTTP reply is displayed.
Fix api.c to support only Ed25519 (not RSA and ECC)
Fix suites.c to detect when CA for client won't work (Ed25519 only)
For Static Memory add debugging and small profile.
Also allow realloc to be called with NULL.
Add more Ed25519 certs and keys.
Fix names of Ed25519 filenames for client and server.
Do NOT turn on ECC_SHAMIR by default with lowresource.
Enable WOLFSSL_STATIC_MEMORY_SMALL if low resource and no RSA.
1. Add a second select for tx.
2. Revised tcp_select to work for either rx or tx.
3. Updated client and server to use new tcp_select_tx() for checking the
tx socket if the nonblocking connect/accept would block on transmit.
1. Fix testing issue with a client using the SCSV cipher suite to indicate desire for renegotiation.
2. Add indication to both the server and client examples that the renegotiation was successful.
1. Add the server side renegotiation flag to the secure renegotiation option.
2. Changed the AddEmptyNegotiationInfo so it doesn't create an extension, just adds a reply if SCR is enabled.
3. Fix the server's reaction to the client sending the SCR extension.
1. Add enables to the example server for turning on secure renegotiation.
2. Add encryption assists to the handhshake message handler functions.
3. Add a hello request message function. Includes handshake timing pre/postambles.
