Functions called from EFI applications should not do console output.
Refactor the wget code to implement this requirement. The wget_http_info
struct is used to hold the boolean that signifies whether the output is
allowed or not.

Make the do_ping() function in cmd/net.c a global one by getting rid of
the static qualifier, and move the prototype declaration from net-lwip.h
to net-common.h. This makes the function available to other parts of
U-Boot when CONFIG_NET=y, as was already the case when
CONFIG_NET_LWIP=y.

This is a peparation step to make the sandbox tests use a common API
between NET and NET_LWIP.

Implement net_start_again() when NET_LWIP=y in a very similar way to
NET. This will be used in a future commit to determine if a failed
ping needs to be tried again on a different interface.

Note that this undoes the changes of commit cf6d4535cc4c ("x86:
emulation: Disable bloblist for now") as that was intended only for the
release due to time.

This reverts commit 8bc3542384e3a1219e5ffb62b79d16dddc1b1fb9, reversing
changes made to 698edd63eca090a2e299cd3facf90a0b97bed677.

There are still problems with this series to work out.

Commit 1d5d292b7941 ("net: split net into net{,-common,-legacy,-lwip}")
inadvertendly left a commented out declaration for do_wget() in
net-common.h. Remove it.

Simon Glass <sjg@chromium.org> says:

This series includes some patches related to allowing read_all() to be
used with the extlinux / PXE bootmeths.

These patches were split out from the stb4 series, since it will need to
have additional patches for LWIP, to avoid breaking PXE booting when
LWIP is used.

Add a new netboot_run() function which can be used for simple network
operations, such as loading a file. Put the implementation in an
internal function, used by the existing code.

Place this function into the net/ code, so that it does not need the
command line to be available.

Document which network operations are supported, i.e. a limited subset,
for now.

For the one board which uses lwip, it is not quite clear how to avoid
using the cmdline interface. This will need some discussion.

The following symbols are exposed:
	- efi_reinstall_protocol_interface
		This is done so that the device path protocol interface
		of the network device can be changed internally by u-boot
		when a new bootfile gets downloaded.
	- eth_set_dev
		To support multiple network udevices
	- efi_close_event
		This comes in preparation to support unregistering
		an EFI network device from the EFI network stack when
		the underlying U-boot device gets removed
	- efi_[dis]connect_controller
		The EFI network driver uses ConnectController to add a
		NIC to the EFI network stack.
	- efi_uninstall_protocol_interface
		connect_controler for the efi network driver can install
		protocols, which need to be uninstalled in disconnect_controller
	- EFI_SIMPLE_NETWORK_PROTOCOL_GUID
