this is an atempt to make the export of functions typesafe.
I replaced the jumptable void ** by a struct (jt_funcs) with function pointers.
The EXPORT_FUNC macro now has 3 fixed parameters and one
variadic parameter
The first is the name of the exported function,
the rest of the parameters are used to format a functionpointer
in the jumptable,
the EXPORT_FUNC macros are expanded three times,
1. to declare the members of the struct
2. to initialize the structmember pointers
3. to call the functions in stubs.c

(resending to the list since my tweaks are not quite trivial)
Add a dm_ prefix to driver model I2C functions so that we can keep the old
ones around.
This is a little unfortunate, but on reflection it is too difficult to
change the API. We can undo this rename when most boards and drivers are
converted to use driver model for I2C.

Add a uclass which provides access to SPI buses and includes operations
required by SPI.
For a time driver model will need to co-exist with the legacy SPI interface
so some parts of the header file are changed depending on which is in use.
The exports are adjusted also since some functions are not available with
driver model.
Boards must define CONFIG_DM_SPI to use driver model for SPI.

(Discussed some follow-up comments which will address in future add-ons)
The spi.h include is no longer included in exports.h, so must be included
here.
This fixes these errors:

This (undocumented) concept was only in use for the MVSMR and
davinci_schmoogie Sergey Kubushyn <ksi@koi8.net> boards.
Drop it for now. If really needed, it should be reimplemented
later in the context of the new environment command set.

The current jump table init fails to initialize a bunch of exported
symbols (forceenv/do_reset/etc...). Rather than fix just these few
missing pieces, rewrite the code to utilize the existing list of
exported symbols -- _exports.h. Since every exported symbol has to
be listed in this header, it makes sense to use it so that we only
ever have one list that needs to be updated and things can't fall
out of sync again.

Additionally export the following fuctions (to make trab_config build again):
- simple_strtol()
- strcmp()
Also bump the ABI version to reflect this change

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.
All transformations are of the form:
Before:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)

applications: instead of using (PPC-specific) system calls we now
use a jump table; please see doc/README.standalone for details
