/**
This function allows the caller to request the current
configuration for one or more named elements. The resulting
string is in <ConfigAltResp> format. Any and all alternative
configuration strings shall also be appended to the end of the
current configuration string. If they are, they must appear
after the current configuration. They must contain the same
routing (GUID, NAME, PATH) as the current configuration string.
They must have an additional description indicating the type of
alternative configuration the string represents,
"ALTCFG=<StringToken>". That <StringToken> (when
converted from Hex UNICODE to binary) is a reference to a
string in the associated string pack.
@param This Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
@param Request A null-terminated Unicode string in
<ConfigRequest> format. Note that this
includes the routing information as well as
the configurable name / value pairs. It is
invalid for this string to be in
<MultiConfigRequest> format.
If a NULL is passed in for the Request field,
all of the settings being abstracted by this function
will be returned in the Results field. In addition,
if a ConfigHdr is passed in with no request elements,
all of the settings being abstracted for that particular
ConfigHdr reference will be returned in the Results Field.
@param 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.
@param Results A null-terminated Unicode string in
<MultiConfigAltResp> format which has all values
filled in for the names in the Request string.
String to be allocated by the called function.
@retval EFI_SUCCESS The Results string is filled with the
values corresponding to all requested
names.
@retval EFI_OUT_OF_RESOURCES Not enough memory to store the
parts of the results that must be
stored awaiting possible future
protocols.
@retval EFI_NOT_FOUND Routing data doesn't match any
known driver. Progress set to the
first character in the routing header.
Note: There is no requirement that the
driver validate the routing data. It
must skip the <ConfigHdr> in order to
process the names.
@retval EFI_INVALID_PARAMETER Illegal syntax. Progress set
to most recent "&" before the
error or the beginning of the
string.
@retval EFI_INVALID_PARAMETER Unknown name. Progress points
to the & before the name in
question.

This function applies changes in a driver's configuration.
Input is a Configuration, which has the routing data for this
driver followed by name / value configuration pairs. The driver
must apply those pairs to its configurable storage. If the
driver's configuration is stored in a linear block of data
and the driver's name / value pairs are in <BlockConfig>
format, it may use the ConfigToBlock helper function (above) to
simplify the job.
@param This Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
@param Configuration A null-terminated Unicode string in

is in the first name / value pair) or
the terminating NULL if all was
