Currently if ${bootfile} is unset and sysboot is invoked with no
filename specified then U-Boot will crash will a null-pointer
dereference. Add the missing check and a matching error print.
Fixes: 993c912d304d ("cmd: sysboot: Create a sysboot command dedicated file")

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
- pxe get -ipv6
- pxe boot -ipv6

The only difference between the three helpers is the filesystem type.
Factor this out and call the filesystem functions directly, instead of
through the command-line interpreter. This allows the file size to be
obtained directly, instead of via an environment variable.
We cannot do the same thing with PXE's tftpboot since there is no API
at present to obtain information about the file that was read. So there
is no point in changing pxe_getfile_func to use a ulong for the address,
for example.
This is as far as the refactoring can go for the present.

It is pretty strange that the pxe code uses the 'filesize' environment
variable find the size of a file it has just read.
Partly this is because it uses the command-line interpreter to parse its
request to load the file.
As a first step towards unwinding this, return it directly from the
getfile() function. This makes the code a bit longer, for now, but will be
cleaned up in future patches.

The 'bootfile' environment variable is read in the bowels of pxe_util to
provide a directory to which all loaded files are relative.
This is not obvious from the API to PXE and it is strange to make the
caller set an environment variable rather than pass this as a parameter.
The code is also convoluted, which this feature implemented by
get_bootfile_path().
Update the API to improve this. Unfortunately this means that
pxe_setup_ctx() can fail, so add error checking.

Both the syslinux and pxe commands use essentially the same code to parse
and run extlinux.conf files. Move this into a common function.

Move the header file into the main include/ directory so we can use it
from the bootmethod code. Move the C file into boot/ since it relates to
booting.

Move this into the context to avoid a global variable. Also rename it
since the current name does not explain what it actually affects.

At present the PXE functions pass around a pointer to command-table entry
which is very strange. It is only needed in a few places and it is odd to
pass around a data structure from another module in this way.
For bootmethod we will need to provide some context information when
reading files.
Create a PXE context struct to hold the command-table-entry pointer and
pass that around instead. We can then add more things to the context as
needed.

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.
