Provide a way to pass the 'fake go' flag from the bootflow flag through
to the PXE implementation, so that a request for a fake go
(via 'bootflow boot -f') is handled correctly in the bootmeth and when
booting.
Add a little more debugging of this in PXE.

If a load-only FIT has already provided a devicetree, PXE boot may need
to restart the bootm sequence, rather than starting an entirely new one,
so that the devicetree is preserved and used for booting.
Add support for this by adding a new field in the context and updating
extlinux_boot() to receive the value as a new parameter.

Add a new extlinux_setup() function which sets things up so that the
bootflow can either be booted, or just probed.
Provide a readall() method so that images can be read into memory,
without booting the OS. Adjust the boot() method so that it can boot,
after any changes have been made by the user.
Update the test to change the bootargs and check that they are booted
with the changes intact.

It is useful to be able to inspect things before the OS is actually
booted, perhaps to check that all is well or to adjust the kernel
command-line. Implement the 'read_all()' method to allow this.
Provide a simple test to check that the images are found.
For now it is not possible to actually continue the uninterrupted boot,
without re-reading all the images.

The extlinux and PXE code for booting is almost the same. Move it into
the common file so it is easier to keep it in sync.

The fallback feature is implemented for extlinux but not for PXE. Move
the code into common files so we can keep both pieces in sync.
Tidy up the comment for set_property() while we are here, fixing the
return value and some missing hyphens.
