These functions are useful for the EFI app. As a first step towards
making these available outside lib/efi_loader, create a separate header
file and include it where needed. Add proper comments to the functions,
since many are missing at present.

We don't want ANSI escape-sequences written in tests since it is a pain
to check the output with ut_assert_nextline() et al.

Provide a way to tests to request that these characters not be sent.

Add a proper function comment while we are here, to encourage others.

Do not try to create an initrd device path nor try to register
an initrd with the EFI_LOAD_FILE2_PROTOCOL if none is provided.

Handle initrd installation in efi_binary_run_dp with
efi_install_initrd, imitating what is done for the fdt.

U-Boot can pass an initrd to subsequent boot stages via the
EFI_LOAD_FILE2_PROTOCOL. The current implementation only supports
this functionality via the efi boot manager: the initrd is taken
from the load options of the BootCurrent variable. This commit adds
support for registering a memory mapped initrd, e.g. loaded from a
FIT image. For now this new method takes precedence over loading the
initrd from the BootCurrent variable (if both are present) because
the BootCurrent variable is not cleared on exiting the boot manager.

With upcoming changes supporting pmem nodes, we need to remove the
pmem area from the EFI memory map. Rename efi_add_memory_map_pg() to
efi_update_memory_map(), and allow removing memory from the EFI memory
map.

Structure jmp_buf_data provides the underlying format of jmp_buf, which
we actually don't care about. Clean up existing code to use the standard
jmp_buf type. This introduces no functional change.

Add support for multiple efi_net_obj structs in efi_net.c. This comes
in preparation for an EFI network driver supporting multiple network
interfaces. For now the EFI network stack still registers a single ethernet
udevice as an EFI network device even if multiple are present, namely
the one that was the current device at the moment of EFI initialization.

In preparation to support mutiple efi net udevices. Add a device path
cache to support device paths from multiple ethernet udevices.
The device paths can be added to the cache before EFI gets initialized and
the protocols get installed.

In preparation to support multiple EFI net objects, support
constructing device paths using an ethernet device different
than the default. Add a udevice argument to the device path
generation, and keep the callsites with eth_get_dev() to
preserve existing functionality.
