Detailed Description

       ESAPI function to invoke the TPM2_ContextLoad command either as a one-call or in an
       asynchronous manner.

Function Documentation

   TSS2_RC Esys_ContextLoad (ESYS_CONTEXT * esysContext, const TPMS_CONTEXT * context, ESYS_TR *
       loadedHandle)
       One-Call function for TPM2_ContextLoad

       This function invokes the TPM2_ContextLoad command in a one-call variant. This means the
       function will block until the TPM response is available. All input parameters are const.
       The memory for non-simple output parameters is allocated by the function implementation.

       Parameters
           esysContext The ESYS_CONTEXT.
           context The context blob.
           loadedHandle ESYS_TR handle of ESYS resource for TPMI_DH_CONTEXT.

       Return values
           TSS2_RC_SUCCESS if the function call was a success.
           TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers or required
           output handle references are NULL.
           TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
           TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for internal operations
           or return parameters.
           TSS2_ESYS_RC_BAD_SEQUENCE if the context has an asynchronous operation already
           pending.
           TSS2_ESYS_RC_INSUFFICIENT_RESPONSE if the TPM's response does not at least contain the
           tag, response length, and response code.
           TSS2_ESYS_RC_MALFORMED_RESPONSE if the TPM's response is corrupted.
           TSS2_ESYS_RC_RSP_AUTH_FAILED if the response HMAC from the TPM did not verify.
           TSS2_RCs produced by lower layers of the software stack may be returned to the caller
           unaltered unless handled internally.

   TSS2_RC Esys_ContextLoad_Async (ESYS_CONTEXT * esysContext, const TPMS_CONTEXT * context)
       Asynchronous function for TPM2_ContextLoad

       This function invokes the TPM2_ContextLoad command in a asynchronous variant. This means
       the function will return as soon as the command has been sent downwards the stack to the
       TPM. All input parameters are const. In order to retrieve the TPM's response call
       Esys_ContextLoad_Finish.

       Parameters
           esysContext The ESYS_CONTEXT.
           context The context blob.

       Return values
           ESYS_RC_SUCCESS if the function call was a success.
           TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers or required
           output handle references are NULL.
           TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
           TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for internal operations
           or return parameters.
           TSS2_RCs produced by lower layers of the software stack may be returned to the caller
           unaltered unless handled internally.

   TSS2_RC Esys_ContextLoad_Finish (ESYS_CONTEXT * esysContext, ESYS_TR * loadedHandle)
       Asynchronous finish function for TPM2_ContextLoad

       This function returns the results of a TPM2_ContextLoad command invoked via
       Esys_ContextLoad_Finish. All non-simple output parameters are allocated by the function's
       implementation. NULL can be passed for every output parameter if the value is not
       required.

       Parameters
           esysContext The ESYS_CONTEXT.
           loadedHandle ESYS_TR handle of ESYS resource for TPMI_DH_CONTEXT.

       Return values
           TSS2_RC_SUCCESS on success
           ESYS_RC_SUCCESS if the function call was a success.
           TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers or required
           output handle references are NULL.
           TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
           TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for internal operations
           or return parameters.
           TSS2_ESYS_RC_BAD_SEQUENCE if the context has an asynchronous operation already
           pending.
           TSS2_ESYS_RC_TRY_AGAIN if the timeout counter expires before the TPM response is
           received.
           TSS2_ESYS_RC_INSUFFICIENT_RESPONSE if the TPM's response does not at least contain the
           tag, response length, and response code.
           TSS2_ESYS_RC_RSP_AUTH_FAILED if the response HMAC from the TPM did not verify.
           TSS2_ESYS_RC_MALFORMED_RESPONSE if the TPM's response is corrupted.
           TSS2_RCs produced by lower layers of the software stack may be returned to the caller
           unaltered unless handled internally.
