The dhcp command is supposed to have the following syntax as per
"help dhcp":
dhcp [loadAddress] [[hostIPaddr:]bootfilename]
In other words, any arguments should be passed to an implicit
tftpboot command after the DHCP exchange has occurred.
Add the missing code to the lwIP version of do_dhcp().

We currently provide entropy to mbedTLS using 8b chunks.
Take into account the 'len' parameter passed by MBed TLS to the entropy
gathering function instead. Note that the current code works because len
is always 128 (defined at compile time), therefore mbedtls_hardware_poll()
is called repeatedly and the buffer is filled correctly. But passing 'len'
to dm_rng_read() is both better and simpler.

The local variables ipstr, maskstr and gwstr in static function
get_udev_ipv4_info() cannot be pointers to read-only data, since
they may be written to in case the device index is > 0. Therefore
make them char arrays allocated on the stack.

With the recent changes of lwip & mbedTLS we can now download from
https:// urls instead of just http://.
Adjust our wget lwip version parsing to support both URLs.
While at it adjust the default TCP window for QEMU since https seems to
require at least 16384

Add support for setting the TFTP block size. The default value (1468)
is fine for Ethernet and allows a better throughput than the TFTP
default (512), if the server supports the blksize option of course.
I tested this change with qemu_arm64_lwip_defconfig. The throughput is
now 875 KiB/s vs. 313 KiB/s before. That is still a low number, but I
think we can't expect more without implementing the windowsize option.

Add support for the wget command with NET_LWIP. The command normally
expects a URL: wget [loadaddr] url, but it also accepts the legacy
syntax: wget [loadaddr] [server:]file.
The server IP may alternatively be supplied via ${httpserverip} which
has higher priority than ${serverip}.
Based on code initially developed by Maxim U.

Add what it takes to enable NETDEVICES with NET_LWIP and enable DHCP as
well as the dhcp command. CMD_TFTPBOOT is selected by BOOTMETH_EFI due
to this code having an implicit dependency on do_tftpb().
Note that PXE is likely non-fonctional with NET_LWIP (or at least not
100% functional) because DHCP option 209 is not supported by the lwIP
library. Therefore, BOOTP_PXE_DHCP_OPTION cannot be enabled.

Prepare the introduction of the lwIP (lightweight IP) TCP/IP stack by
adding a new net/lwip/ directory and the NET_LWIP symbol. Network
support is either NO_NET, NET (legacy stack) or NET_LWIP. Subsequent
commits will introduce the lwIP code, re-work the NETDEVICE integration
and port some of the NET commands and features to lwIP.
SPL_NET cannot be enabled when NET_LWIP=y. SPL_NET pulls some symbols
that are part of NET (such as arp_init(), arp_timeout_check(),
arp_receive(), net_arp_wait_packet_ip()). lwIP support in SPL may be
added later.
Similarly, DFU_TFTP and FASTBOOT are not compatible with NET_LWIP
because of dependencies on net_loop(), tftp_timeout_ms,
tftp_timeout_count_max and other NET things. Let's add a dependency on
!NET_LWIP for now.
SANDBOX can select NET_LWIP but doing so will currently disable the eth
dm tests as well as the wget tests which have strong dependencies on the
NET code.
Other adjustments to Kconfig files are made to fix "unmet direct
dependencies detected" for USB_FUNCTION_SDP and CMD_FASTBOOT when
the default networking stack is set to NET_LWIP ("default NET_LWIP"
instead of "default NET" in Kconfig).
The networking stack is now a choice between NO_NET,
NET and NET_LWIP. Therefore '# CONFIG_NET is not set' should be
'CONFIG_NO_NET=y'. Adjust the defconfigs accordingly.
