The implementation in extlinux_pxe_getfile() does not pass a valid size
to bootmeth_read_file(), so this can fail if the uninited value happens to
be too small.
Fix this.

We use the terms 'distro' to mean extlinux but they are not really the
same. 'Distro' could refer to any method of booting a distribution,
whereas extlinux is a particular method.
Also we sometimes use syslinux, but it is better to use the same term in
all cases.
Rename distro to syslinux and also update bootstd uses of syslinux to use
extlinux instead.

Adds commands to support DHCP and PXE with IPv6.
New configs added:
- CMD_DHCP6
- DHCP6_PXE_CLIENTARCH
- DHCP6_PXE_DHCP_OPTION
- DHCP6_ENTERPRISE_ID
New commands added (when IPv6 is enabled):
- dhcp6

These are associated with the ethernet boot device but do not match its
uclass name, so handle them as special cases.
Provide a way to pass flags through with the bootdev so that we know
how to process it. The flags are checked by the bootmeths, to ensure that
only the selected bootmeth is used.
While these both use the network device, they work quite differently. It
is common to run only one of these, or to run PXE before DHCP. Provide
bootflow flags to control which methods are used. Check these in the two
bootmeths so that only the chosen one is used.

Add a bootmeth driver which handles distro boot from a network device, so
we can boot a bootflow using this commonly used mechanism.
In effect, this provides the same functionality as the 'pxe' command
and shares the same code. But the interface into it is via a bootmeth.
For now this requires the 'pxe' command be enabled. Future work may tidy
this up so that it can be used without CONFIG_CMDLINE being enabled.
