Standard Libraries for EDK II.

This set of three packages: AppPkg, StdLib, StdLibPrivateInternalFiles; contains the implementation of libraries based upon non-UEFI standards such as ISO/IEC-9899, the library portion of the C Language Standard, POSIX, etc.

AppPkg contains applications that make use of the standard libraries defined in the StdLib Package.

StdLib contains header (include) files and the implementations of the standard libraries.

StdLibPrivateInternalFiles contains files for the exclusive use of the library implementations in StdLib.  These files should never be directly referenced from applications or other code.
