In the URI device path node, any name rahter than address can be used for
looking up the resources so that DNS service become needed to get answer of the
name's address. Unfortunately the DNS is not defined in any of the device path
nodes so that we use the EFI_IP4_CONFIG2_PROTOCOL and EFI_IP6_CONFIG_PROTOCOL
to obtain it.
These two protcols are defined the sections of UEFI specification.
27.5 EFI IPv4 Configuration II Protocol
27.7 EFI IPv6 Configuration Protocol
include/grub/efi/api.h:
Add new structure and protocol UUID of EFI_IP4_CONFIG2_PROTOCOL and
EFI_IP6_CONFIG_PROTOCOL.
grub-core/net/drivers/efi/efinet.c:
Use the EFI_IP4_CONFIG2_PROTOCOL and EFI_IP6_CONFIG_PROTOCOL to obtain the list
of DNS server address for IPv4 and IPv6 respectively. The address of DNS
servers is structured into DHCPACK packet and feed into the same DHCP packet
processing functions to ensure the network interface is setting up the same way
it used to be.

The PXE Base Code protocol used to obtain cached PXE DHCPACK packet is no
longer provided for HTTP Boot. Instead, we have to get the HTTP boot
information from the device path nodes defined in following UEFI Specification
sections.
9.3.5.12 IPv4 Device Path
9.3.5.13 IPv6 Device Path
9.3.5.23 Uniform Resource Identifiers (URI) Device Path
This patch basically does:
include/grub/efi/api.h:
Add new structure of Uniform Resource Identifiers (URI) Device Path
grub-core/net/drivers/efi/efinet.c:
Check if PXE Base Code is available, if not it will try to obtain the netboot
information from the device path where the image booted from. The DHCPACK
packet is recoverd from the information in device patch and feed into the same
DHCP packet processing functions to ensure the network interface is setting up
the same way it used to be.

When grub2 image is booted from UEFI IPv6 PXE, the DHCPv6 Reply packet is
cached in firmware buffer which can be obtained by PXE Base Code protocol. The
network interface can be setup through the parameters in that obtained packet.

UEFI specification 2.8 errata B introduced the EFI_RT_PROPERTIES_TABLE
describing the services available at runtime.
The lsefisystab command is used to display installed EFI configuration
tables. Currently it only shows the GUID but not a short text for the
new table.
Provide a short text for the EFI_RT_PROPERTIES_TABLE_GUID.

Several places we take the length of a device path and subtract 4 from
it, without ever checking that it's >= 4. There are also cases where
this kind of malformation will result in unpredictable iteration,
including treating the length from one dp node as the type in the next
node. These are all errors, no matter where the data comes from.
This patch adds a checking macro, GRUB_EFI_DEVICE_PATH_VALID(), which
can be used in several places, and makes GRUB_EFI_NEXT_DEVICE_PATH()
return NULL and GRUB_EFI_END_ENTIRE_DEVICE_PATH() evaluate as true when
the length is too small. Additionally, it makes several places in the
code check for and return errors in these cases.

Currently, in some builds with some checkers, we see:
1. grub-core/disk/efi/efidisk.c:601: error[shiftTooManyBitsSigned]: Shifting signed 64-bit value by 63 bits is undefined behaviour
This is because grub_efi_status_t is defined as grub_efi_intn_t, which is
signed, and shifting into the sign bit is not defined behavior. UEFI fixed
this in the spec in 2.3:
2.3 | Change the defined type of EFI_STATUS from INTN to UINTN | May 7, 2009
