CopyObject meta request bug fixes

Invoke headers callback when CopyObject request is bypassed

Prior to this fix the headers callback was invoked only
when the Copy meta request performed a multi-part copy, but not
when the object was small and resulted in a bypassed CopyObject request.

This commit fixes the issue, invoking the headers callback
in both cases.

Support leading slash in x-amz-copy-source

The CopyObject meta request required the x-amz-copy-source to be in strict form of {bucket}/{key}.
But as per S3 docs, /{bucket}/{key} is also valid.

This fix adds support for both formats.

Remove Content-MD5 in CopyObject meta request

The Content-MD5 header is not supported in UploadPartCopy
requests. This update removes the logic that would compute
Content-MD5 when it was included in the meta request.

CopyObject progress callback

• Added progress callback to CopyObject meta request
• Updated CLI sample to show progress bar when copying objects from S3 to S3

CopyObject meta request and sample command line application

• The new meta request type AWS_S3_META_REQUEST_TYPE_COPY_OBJECT performs a multi-part copy using multiple UploadPartCopy requests in parallel, or bypasses a CopyObject request to S3 if the object size is not large enough for a multipart upload
• Command line sample app similar to aws-cli s3 command implementing cp and ls

Enable headers callback invocation for failed requests

For Default meta requests, the response headers callback was called
only for successful responses. This release enables the callback invocation on errors too.
