//*** CommandAuditPreInstall_Init()
// This function initializes the command audit list. This function simulates
// the behavior of manufacturing. A function is used instead of a structure
// definition because this is easier than figuring out the initialization value
// for a bit array.
//
// This function would not be implemented outside of a manufacturing or
// simulation environment.

//*** CommandAuditStartup()
// This function clears the command audit digest on a TPM Reset.

//*** CommandAuditSet()
// This function will SET the audit flag for a command. This function
// will not SET the audit flag for a command that is not implemented. This
// ensures that the audit status is not SET when TPM2_GetCapability() is
// used to read the list of audited commands.
//
// This function is only used by TPM2_SetCommandCodeAuditStatus().
//
// The actions in TPM2_SetCommandCodeAuditStatus() are expected to cause the
// changes to be saved to NV after it is setting and clearing bits.

// The actions in TPM2_SetCommandCodeAuditStatus() are expected to cause the
