HandleProtocol() is deprecrated. According to the UEFI specification it
should be implemented as a call to  OpenProtocolInterface() with a hard
coded agent handle. This implies that we would have to call
CloseProtocolInterfaces() after usage with the same handle.

Getting rid of an EFI_CALL() is also appreciated.

The fields ConsoleInHandle, ConsoleOutHandle, ConsoleErrHandle must point
to the handles with the respective console protocols. Failure to do so
leads to an error in the EFI Shell:

    No SimpleTextInputEx was found. CTRL-based features are not usable.

If the va_list we got handed over contains no protocols we must return
EFI_SUCCESS.  However in that case the current code just returns
an unintialized value.
Fix that by setting the return value in the variable definition

A following patch is cleaning up the core EFI code trying to remove
sequences of efi_create_handle, efi_add_protocol.

Although this works fine there's a problem with the latter since it is
usually combined with efi_delete_handle() which blindly removes all
protocols on a handle and deletes the handle.  We should try to adhere to
the EFI spec which only deletes a handle if the last instance of a protocol
has been removed.  Another problem is that efi_delete_handle() never checks
for opened protocols,  but the EFI spec defines that the caller is
responsible for ensuring that there are no references to a protocol
interface that is going to be removed.

So let's fix this by replacing all callsites of
efi_create_handle(), efi_add_protocol() , efi_delete_handle() with
Install/UninstallMultipleProtocol.

In order to do that redefine functions that can be used by the U-Boot
proper internally and add '_ext' variants that will be used from the
EFI API

This commit add the "eficonfig" command.
The "eficonfig" command implements the menu-driven UEFI boot option
maintenance feature. This commit implements the addition of
new boot option. User can select the block device volume having
efi_simple_file_system_protocol and select the file corresponding
to the Boot#### variable. User can also enter the description and
optional_data of the BOOT#### variable in utf8.

This commit adds "include/efi_config.h", it contains the common
definition to be used from other menus such as UEFI Secure Boot
key management.
