--- single return point
--- changed stack reduction MEMORY_E to -1 to match XMALLOC fail at httpBuf
--- variable written removed
--- variable ocspRespSz renamed to ret (initialized with -1 and set only once with process_http_response result)
--- use ShaHash instead of InitSha, ShaUpdate and ShaFinal (sizeof(Sha) saved)
io: refactoring EmbedOcspLookup to reduce stack usage:
--- variable domainName moved to the heap (80 bytes saved)
--- variable path moved to the heap (80 bytes saved)
1. Change `CyaSSL_OCSP_set_options()` to return `SSL_SUCCESS`
or `SSL_FAILURE` as `int` like rest of API.
2. Fix data narrowing warning in file io.c function
`process_http_response()`.
3. Fix global variable shadowed warning in file ssl.c function
`CyaSSL_GetSessionAtIndex()`
4. Fix data narrowing warning in file internal.c functions
`Encrypt()` and `Decrypt()`. Passed in a word32 size parameter
that was provided a word16 and used as a word16.
5. Removed unreachable code from file tls.c function
`CyaSSL_GetHmacType()`.
6. Fix data narrowing warnings in file aes.c functions
`AesCcmEncrypt()` and `AesCcmDecrypt()`.
1. Add option to example server and client to check the OCSP responder.
2. Add option to example server and client to override the URL to use
when checking the OCSP responder.
3. Copy the certificate serial number correctly into OCSP request.
Add leading zero only if MS bit is set.
4. Fix responder address used when Auth Info extension is present.
5. Update EmbedOcspLookup callback to better handle the HTTP
response and obtain the complete OCSP response.
1. When doing the HTTP transaction, use recv() and send().
2. When a cert doesn't have an Auth Info extension, and not using
an override server, it is considered good.
3. decode_url() should return -1 in case of error.
4. When decoding HTTP response, process all the headers, skipping all
of those that are not-processed.
