This adds support for using USB Ethernet dongles in host mode. This is just
the framework - drivers will come later. A new config option called
CONFIG_USB_HOST_ETHER can be defined in board config files to switch this
on.

The was originally written by NVIDIA and was cleaned up for release by the
Chromium authors.

This has always been confusing, and the idea of these functions returning the
number of interfaces initialized was half-baked and ultimately pointless.
Instead, act more like regular functions and return < 0 on failure, >= 0 on
success.

This change shouldn't break anything.

Commit 6e37b1a3a25004d3df5867de49fff6b3fc9c4f04 modifies several net calls
to take a (const char *) parameter instead of (char *), but in some cases
the modified functions call other functions taking (char *).  The end result
is warnings about discarding the const qualifier.

This patch fixes these other function signatures.

Some commands operate on eth device names (like 'mii'), but those cannot
be passed on the command line as one argument.  So detect devices like
these and warn about them so someone will fix it.

Add a new function to the eth_device struct for programming a network
controller's hardware address.

After all network devices have been initialized and the proper MAC address
for each has been determined, make a device driver call to program the
address into the device.  Only device instances with valid unicast addresses
will be programmed.

In the previous enetaddr refactoring, the assumption with commit 56b555a6
was that the eth layer would handle the env -> device enetaddr syncing.
This was not the case as eth_initialize() is called only once and the sync
occurs there.  So make sure the eth_init() function does the env -> device
sync with every network init.

 Minor ./net cleanups - no functional changes
  - change #ifdef DEBUG printf(); #endif to just debug()
  - changed __FUNCTION__ to __func__
  - got rid of extra whitespace between function and opening brace
  - removed unnecessary braces on if statements

 gcc dead code elimination should make this functionally/size equivalent
 when DEBUG is not defined. (confirmed on Blackfin, with gcc 4.3.3).

Declare new utility functions for converting between the environment
variables (eth*addr) and the binary MAC address representation.  This way
we can unify all the random places that already do this kind of thing.

The functions in question:
	eth_parse_enetaddr - "..." -> {...}
	eth_getenv_enetaddr - env -> {...}
	eth_setenv_enetaddr - {...} -> env

NetLoop polls every cycle with getenv some environment variables.
This is horribly slow, especially when the environment is big.

This patch reads only the environment variables in NetLoop,
when they were changed.

Also moved the init part of the NetLoop function in a seperate
function.
