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.

Unfortunately SDL requires getenv() to operate, since it wants to figure out
the display type. U-Boot has its own getenv() and they conflict. As a
work-around use #define to resolve the conflict.
A better but more complex solution might be to rename some U-Boot symbols
at link time. SDL audio is not functional at present, likely due to a related

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

We can use SDL to provide emulation of these basic functions for sandbox.

ush: ehci: initialize altnext pointers in QH
Section 4.10.2 "Advance Queue" of ehci-specification-for-usb.pdf
specifies how an EHCI controller loads a new QTD for processing if the
QH is not already marked as active. It states:
=====
If the field Bytes to Transfer is not zero and the T-bit in the Alternate
Next qTD Pointer is set to zero, then the host controller uses the
Alternate Next qTD Pointer. Otherwise, the host controller uses the Next
qTD Pointer. If Next qTD Pointer’s T-bit is set to a one, then the host
controller exits this state and uses the horizontal pointer to the next
schedule data structure.
=====
Hence, we must ensure that the alternate next QTD pointer's T-bit
(TERMINATE) is set, so the EHCI controller knows to use the next QTD
pointer.

cfb_console: align fields in gzipped .bmp files
.bmp files contain 32-bit integers aligned at offsets of +2, +6,
et cetera within the bmp_header structure (see include/bmp_layout.h).
Support for gzip-compressed .bmp files is present in the cfb_console
display subsystem by uncompressing them prior to use.
This patch forces the in-memory header to be aligned properly
for these compressed images by extracting them to a 2-byte
offset in the memory returned by malloc. Since malloc will always
return a 4-byte aligned value, this forces the .bmp header
fields to be naturally aligned on 4-byte addresses.
Refer to these files for more details:
