+ The EFI_FORM_BROWSER_PROTOCOL is the interface to the EFI
+ Configuration Driver. This will allow the caller to direct the
+ configuration driver to use either the HII database or use the passed
+ in packet of data. This will also allow the caller to post messages
+ into the configuration drivers internal mailbox.

+ pointer to the calling driver's callback interface.
+
+ @param This A pointer to the EFI_FORM_BROWSER_PROTOCOL instance.
+ @param UseDatabase Determines whether the HII database is to be
+ used to gather information. If the value is FALSE, the configuration
+ driver will get the information provided in the passed-in Packet parameters.
+ @param Handle A pointer to an array of HII handles to display. This value
+ should correspond to the value of the HII form package that is required to
+ be displayed.
+ @param HandleCount The number of handles in the array specified by Handle.
+ @param Packet A pointer to a set of data containing pointers to IFR
+ and/or string data.
+ @param CallbackHandle The handle to the driver's callback interface.
+ This parameter is used only when the UseDatabase parameter is FALSE
+ and an application wants to register a callback with the browser
+ @param NvMapOverride This buffer is used only when there is no NV variable
+ to define the current settings and the caller needs to provide to the browser
+ the current settings for the "fake" NV variable.
+ @param ScreenDimensions Allows the browser to be called so that it occupies
+ a portion of the physical screen instead of dynamically determining the
+ screen dimensions.
+ @param ResetRequired This BOOLEAN value will tell the caller if a reset
+ is required based on the data that might have been changed. The ResetRequired
+ parameter is primarily applicable for configuration applications, and is an
+ optional parameter.
+
+ @retval EFI_SUCCESS The function completed successfully
+ @retval EFI_NOT_FOUND The variable was not found.
+ @retval EFI_BUFFER_TOO_SMALL The DataSize is too small for the result.
+ DataSize has been updated with the size needed to complete the request.
+ @retval EFI_INVALID_PARAMETER One of the parameters has an invalid value.
+ @retval EFI_DEVICE_ERROR The variable could not be saved due to a hardware failure.
