This series adds various new features to the EFI app, mostly by moving
code over from the EFI loader implementation.

In particular it adds support for the efidebug command (with only a
subset of subcommands so far).

The main approach is to make use of the system table (for both the app
and the loader) instead of directly calling EFI-loader code.

It also includes a few fixes, which likely have no effect but will help
to avoid confusion in future.

Changes in v2:
- Mention the 'dh' subcommand
- Mention that 'order' allows the boot order to be changed
- Mention the eficonfig command and the underlying UEFI firmware
