[RFC PATCH v2 0/4] enable menu-driven boot device selection

[Masahisa Kojima]

This patch series adds the menu-driven boot device selection.
This menu also provides the functionality to add and delete
Boot#### variable, and edit the BootOrder variable.

This menu appears with the command "bootefi bootmgr",
the menu structure is as follows.

* Menu structure
[Boot Manager]
    -> select Boot#### to boot
[Boot Manager Maintenance]
    - [Add Boot Option]
        -> add new Boot#### variable
    - [Delete Boot Option]
        -> delete existing Boot#### variable
    - [Change Boot Order]
        -> update BootOrder variable

* Things to consider
 - eliminate EFI_CALLs
 - replacement of ANSI_CLEAR_CONSOLE

* Remaining items
 - Support of adding Boot#### other than block device(e.g. network)
 - error notification
