According to the ACPI specification the XSDT Entry field contains an array
of 64-bit physical addresses which points to other DESCRIPTION_HEADERs. However,
the entry_ptr iterator is defined as a 32-bit pointer. It means each 64-bit
entry in the XSDT table is treated as two separate 32-bit entries then. Fix the
issue by using correct addresses sizes when processing RSDT and XSDT tables.

The function argp_parser() in util/grub-mount.c lacks a check on the
sanity of the file path when parsing parameters. This results in
a segmentation fault if a partition is mounted to a non-existent path.

According to the ACPI specification, in ACPI 2.0 or later, an
ACPI-compatible OS must use the XSDT if present. So, we should
use xsdt_addr instead of rsdt_addr if xsdt_addr is valid.

During UEFI PXE boot in IPv6 network, if the DHCP server adopts stateful
automatic configuration, then the client receives a ICMP6_ROUTER_ADVERTISE
multicast message from the server. This may be received without the interface
having a configured network address, so orig_inf will be NULL, which can lead
to a NULL dereference when creating the default route. Actually, in this case,
the client obtains the default route through DHCPv6 instead of RA messages.
So if orig_inf == NULL and route_inf == NULL, we should not set the
default route.
