Add a Shell Hot Fix patch to solve RFC3066 language compatibility issue and "CHAR8" compatibility issue (EDK define CHAR8 as "unsigned char" while ECP choose to use "signed char") git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@5682 6f19259b-4bc3-4df7-8a09-765794883524

+ Routine Description:

+ This function matches the major language code (first two characters) in the

+ such match, then NULL is returned.

+ Arguments:
+
+ SupportedLanguages - A Null-terminated ASCII string that contains one
+ or more supported language codes.
+
+ LangCode - A pointer to a Null-terminated ASCII string
+ array indicating the RFC 3066 language.
+
+ Returns:
+
+ The RFC3066 language code that matches the major language.
