The UEFI shim includes a "shim lock protocol" that can be used by a
third party second stage loader such as GRUB to verify a kernel image.
Add definitions for the relevant portions of this protocol interface.

Use '%p' directive, and print handle's address if the address is null
and the handle doesn't have a name. This fixes the following
compilation error:
interface/efi/efi_debug.c:334:3: error: '%s' directive
argument is null [-Werror=format-overflow=]

Add definitions of protocols observed to be used by wdsmgfw.efi, and
add a handle name type for ConIn, ConOut, and StdErr.

Add debug wrappers for more boot services functions, and print
symbolic values rather than raw numbers where possible.

The raw EFI_HANDLE value is almost never useful to know, and simply
adds noise to the already verbose debug messages. Improve the
legibility of debug messages by using only the name generated by
efi_handle_name().

The current API for Base16 (and Base64) encoding requires the caller
to always provide sufficient buffer space. This prevents the use of
the generic encoding/decoding functionality in some situations, such
as in formatting the hex setting types.
Implement a generic hex_encode() (based on the existing
format_hex_setting()), implement base16_encode() and base16_decode()
in terms of the more generic hex_encode() and hex_decode(), and update
all callers to provide the additional buffer length parameter.

Provide a function efi_handle_name() (as a generalisation of
efi_handle_devpath_text()) which tries various methods to produce a
human-readable name for an EFI handle.

Some UEFI systems (observed with a Mac Pro) do not provide
EFI_DEVICE_PATH_TO_TEXT_PROTOCOL. Since we use this protocol only for
debug messages, make it optional and fall back to printing the raw
device path bytes.

Exploit the redefinition of iPXE error codes to include a "platform
