This adds support for specifying FDT overlays in an extlinux/pxelinux
configuration file.
Without this, there is no simple way to apply overlays when the kernel
and fdt is loaded by the pxe command.
This change adds the 'fdtoverlays' keyword for a label, supporting multiple
overlay files to be applied on top of the fdt specified in the 'fdt' or
'devicetree' keyword.
Example:
label linux
kernel /Image
fdt /soc-board.dtb
fdtoverlays /soc-board-function.dtbo
append console=ttyS0,115200 root=/dev/mmcblk0p2 rootwait
This code makes usage of a new variable called fdtoverlay_addr_r used to load
the overlay files without overwritting anything important.

At present cli_simple_process_macros() requires that the caller provide
an output buffer that is exactly CONFIG_SYS_CBSIZE bytes in length. This
makes sense since it is designed to be used from the command line. But we
also want to use it for bootargs substitution.
Update the function to allow the caller to specify the buffer size. Also
return an error if the buffer is exhausted. The caller can ignore that if
preferred.

As FDTDIR label doesn't specify exact file to be loaded, it should
not fail if no file exists in the directory. In this case try to boot
with internal FDT if it exists.

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.

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.
Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

Currently displaying status line is done in a weak function
menu_display_statusline().
bootmenu.c overrides the weak default function.
It calls menu_default_choice() and interprets the data as
struct bootmenu_entry.
pxe boot also uses common menu code for pxe menus.
If there is a system that enables both bootmenu and pxe,
menu_display_statusline() defined in bootmenu.c will be called
and it will interpret struct pxe_label as struct bootmenu_entry.
This leads to data aborts and pxe menu corruptions.
This patch adds support for client defined statusline function
to resolve the above bug.

Execute the command cls (for clear screen), when the "menu background"
keyword is present in extlinux.conf file, only if the command is supported.
This patch avoid the warning "Unknown command 'cls'"
with "menu background" in extlinux.conf when CONFIG_CMD_BMP is activated
and CONFIG_CMD_CLS not activated (default for CONFIG_DM_VIDEO).

These global variables are quite short and generic. In fact the same name
is more often used locally for struct members and function arguments.
Add a image_ prefix to make them easier to distinguish.

On NixOS, cross compiled kernels have long suffixes that cause them to
exceed the current maximum path length. The PXE/TFTP max path length is
used for extlinux.conf support as well, which is where this problem
usually manifest's itself.
