Support tracing on sandbox by adding suitable CONFIG options. To enable it,
compile U-Boot with FTRACE=1.

The timer functions are marked to skip tracing, since these are called from
the tracing code itself, and we want to avoid an infinite loop.

This implementation uses opendir()/readdir() to access the directory
information and then puts it in a linked list for the caller's use.

Implements the tstc() interface for the serial driver.  Multiplexing
the console between the serial port and a keyboard uses a polling
method of checking if characters are available; this means that the
serial console must be non-blocking when attempting to read
characters.

This adds simple command-line parsing to sandbox. The idea is that it
sets up the state with options provided, and this state can then be
queried later, as needed.

New flags are declared with the SB_CMDLINE_OPT_SHORT helper macro,
pointers are automatically gathered up in a special section, and
then the core code takes care of gathering them up and processing
at runtime.  This way there is no central place where we have to
store a list of flags with ifdefs.

This provides a way for callers to create files for writing. The flags
are translated at runtime, for the ones we support.

We want to keep all OS-dependent code in once place, with a simple interface

This adds basic files for the sandbox board. The lds file is very simple
since we can rely mostly on the linker defaults.
