Routine Description:
This routine parses multi-strings of the form
"foo" "bar" "bletch"
Each time it is called, it strips the first string in quotes from
the input string, and returns it as the multi-string.
INPUT ValueString: "foo" "bar" "bletch"
OUTPUT ValueString: "bar" "bletch"
MultiString: foo
Arguments:
ValueString - Supplies the string from which the multi-string will be
parsed
- Returns the remaining string after the multi-string is
removed
MultiString - Returns the multi-string removed from ValueString
Return Value:
TRUE - multi-string found and removed.
FALSE - no more multi-strings remaining.

Routine Description:
The RtlPrefixUnicodeString function determines if the String1
counted string parameter is a prefix of the String2 counted string
parameter.
The CaseInSensitive parameter specifies if case is to be ignored when
doing the comparison.
Arguments:
String1 - Pointer to the first unicode string.
String2 - Pointer to the second unicode string.
CaseInsensitive - TRUE if case should be ignored when doing the
comparison.
Return Value:
Boolean value that is TRUE if String1 equals a prefix of String2 and
FALSE otherwise.
