Enhance QMHRTVM with Message_ID

QMHRTVM is used to return the 1st and 2nd level message text for a specific MSGID from a *MSGF. However, API formats RTVM0300 and RTVM0400 are the only formats that return the actual MSGID of the message being retrieved. Formats 100 and 200 do not.
Add 2 new API return formats, perhaps RTVM0150 and RTVM0250 that are the same as their 100/200 version except these new formats would include the Message_ID, as follows:

typedef _Packed struct Qmh_Rtvm_RTVM0150
{
int Bytes_Return;
int Bytes_Available;
char Message_ID[7];
char Reserved[1];
int Length_Message_Returned;
int Length_Message_Available;
int Length_Help_Returned;
int Length_Help_Available;
/*char Message[];*/ /* Varying length */
/*char Message_Help[];*/ /* Varying length */
} Qmh_Rtvm_RTVM0150_t;

typedef _Packed struct Qmh_Rtvm_RTVM0250
{
int Bytes_Return;
int Bytes_Available;
char Message_ID[7];
char Reserved2[1];
int Message_Severity;
int Alert_Index;
char Alert_Option[9];
char Log_Indicator[1];
char Reserved[2];
int Length_Reply_Returned;
int Length_Reply_Available;
int Length_Message_Returned;
int Length_Message_Available;
int Length_Help_Returned;
int Length_Help_Available;
/*char Default_Reply[];*/ /* Varying length */
/*char Message[];*/ /* Varying length */
/*char Message_Help[];*/ /* Varying length */
} Qmh_Rtvm_RTVM0250_t;

The QMHRTVM API supports a "Format Control" parameter that allows users to specify *FIRST, *NEXT or *MSGID as the message whose info is returned. However, when format 100 or 200 is used, the message ID of the actual message whose info is returned is not itself returned.
This means that when a user of this API wants only the first/second level msg text or perhaps the Severity, they MUST use format 0300 or 0400 which are must larger and more complex and return info that isn't needed in this context.
