sandbox: Add options to clean up temporary files
When jumping from one sandbox U-Boot to another in sandbox, the RAM buffer
is preserved in the jump by using a temporary file. Add an option to tell
the receiving U-Boot to remove this file when it is no longer needed.
Similarly the old U-Boot image is left behind in this case. We cannot delete
it immediately since gdb cannot then find its debug symbols. Delete it just
before exiting.
Together these changes ensure that temporary files are removed both for
memory and U-Boot.

sandbox: Add SDL library for LCD, keyboard, audio
SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which
provides simple graphics and sound features. It works under X11 and also
with a simple frame buffer interface. It is ideally suited to sandbox
U-Boot since it fits nicely with the low-level feature set required by
U-Boot. For example, U-Boot has its own font drawing routines, its own
keyboard processing and just needs raw sound output.
We can use SDL to provide emulation of these basic functions for sandbox.
This significantly expands the testing that is possible with sandbox.
Add a basic SDL library which we will use in future commits.

sandbox: Add facility to save/restore sandbox state
It is often useful to be able to save out the state from a sandbox test
run, for analysis or to restore it later to continue a test. Add generic
infrastructure for doing this using a device tree binary file. This is
a flexible tagged file format which is already supported by U-Boot, and
it supports hierarchy if needed.

sandbox: Allow reading/writing of RAM buffer
It is useful to be able to save and restore the RAM contents of sandbox
U-Boot either for setting up tests, for later analysys, or for chaining
together multiple tests which need to keep the same memory contents.
Add a function to provide a memory file for U-Boot. This is read on
start-up and written when shutting down. If the file does not exist
on start-up, it will be created when shutting down.

sandbox: Add CONFIG_OF_HOSTFILE to read FDT from host file
With sandbox it is tricky to add an FDT to the image at build time (or
later) since we build an ELF file, not a plain binary, and the address
space of the whole U-Boot is not accessible in the emulated memory map
of sandbox.
Sandbox can read files directly from the host, though, so add an option
to read an FDT from a host file on start-up.
