347d06dec4 sandbox: fix the return type of os_free() function
The function os_free() returns nothing.
Its return type should be "void" rather than "void *".

5c2859cdc3 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.

91b136c798 sandbox: Allow the console to work earlier
With sandbox, errors and problems may be reported before console_init_f()
is executed. For example, an argument may not parse correctly or U-Boot may
panic(). At present this output is swallowed so there is no indication what
is going wrong.

Adjust the console to deal with a very early sandbox setup, by detecting that
there is no global_data yet, and calling os functions in that case.

Implement realloc() and free() for sandbox, by adding a header to each
block which contains the block size.

2a54d1599f sandbox: Use uint64_t instead of u64 for time
The uint64_t type is defined in linux/types.h, so is safer than u64, which
is not actually a Linux type.

62584db191 sandbox: Add a way of obtaining directory listings
This implementation uses opendir()/readdir() to access the directory
information and then puts it in a linked list for the caller's use.

e101550a9a sandbox: Improve sandbox serial port keyboard interface
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.

70db4212fc sandbox: add getopt support
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.
