/*++
Routine Description:
This function allows a caller to extract the current configuration for one
or more named elements from the target driver.
Arguments:
This - Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
Request - A null-terminated Unicode string in <ConfigRequest> format.
Progress - On return, points to a character in the Request string.
Points to the string's null terminator if request was successful.
Points to the most recent '&' before the first failing name/value
pair (or the beginning of the string if the failure is in the
first name/value pair) if the request was not successful.
Results - A null-terminated Unicode string in <ConfigAltResp> format which
has all values filled in for the names in the Request string.
String to be allocated by the called function.
Returns:
EFI_SUCCESS - The Results is filled with the requested values.
EFI_OUT_OF_RESOURCES - Not enough memory to store the results.
EFI_INVALID_PARAMETER - Request is NULL, illegal syntax, or unknown name.
EFI_NOT_FOUND - Routing data doesn't match any storage in this driver.

Routine Description:

Arguments:

Configuration - A null-terminated Unicode string in <ConfigResp> format.
Progress - A pointer to a string filled in with the offset of the most
recent '&' before the first failing name/value pair (or the
beginning of the string if the failure is in the first
name/value pair) or the terminating NULL if all was successful.
Returns:
EFI_SUCCESS - The Results is processed successfully.

Routine Description:
This function processes the results of changes in configuration.
Arguments:

Action - Specifies the type of action taken by the browser.
QuestionId - A unique value which is sent to the original exporting driver
so that it can identify the type of data to expect.
Type - The type of value for the question.
Value - A pointer to the data being sent to the original exporting driver.
ActionRequest - On return, points to the action requested by the callback function.
Returns:
EFI_SUCCESS - The callback successfully handled the action.
EFI_OUT_OF_RESOURCES - Not enough storage is available to hold the variable and its data.
EFI_DEVICE_ERROR - The variable could not be saved.
EFI_UNSUPPORTED - The specified Action is not supported by the callback.
