Abstracted out part of the concept of an SPI device to a generalised NVS
device.
Separated the mechanisms of non-volatile storage access and non-volatile
stored options.

Changed length parameter in SPI methods to be a byte length, rather than
a word length.

Generalised the SPI abstraction layer to also be able to handle interfaces
that don't provide the full flexibility of a bit-bashing interface.
Temporarily hacked rtl8139.c to use the new interface.

We don't actually have a stdio.h header file. Our printf() functions are
defined in vsprintf.h. (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)
There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.

Update rtl8139 driver to instantiate an SPI interface with a three-wire
device attached.

Move per-transition delays from generic bit-bashing layer to i2c layer
(since SPI bit-bashing will require different delay semantics).
