[PATCH v2 0/8] sandbox: implement cold reset

[Heinrich Schuchardt]

The command to shut down a device is 'poweroff'. It is a deficit of the
sandbox that it does not support resetting yet but shuts down upong seeing
the 'reset' command.

The patch series implements the cold reset function as a relaunch of the
U-Boot binary via execv().

Unit tests are adjusted.

A bug leading to closing the console input file descriptor is resolved.

Add some of the sandbox API to the HTML documentation.

v2:
	use O_CLOEXEC in os_open()
	avoid longjmp()
	add more comments
	add the os.h to the HTML documentation
