automount: check for recursive automount ...

automount_mount calls run_command which may trigger an automount
again. This results in an endless loop. A simple way to trigger
this is:

mkdir /x; automount /x false; cd /x; something

Use a static variable to detect if we are currently in automount_mount()
and bail out if we are.

lz4: fix another possible overrun ...

Note: this is the same as 4148c1f in
linux-git.

There is one other possible overrun in the lz4 code as implemented by
Linux at this point in time (which differs from the upstream lz4
codebase, but will get synced at in a future kernel release.)  As
pointed out by Don, we also need to check the overflow in the data
itself.

While we are at it, replace the odd error return value with just a
"simple" -1 value as the return value is never used for anything other
than a basic "did this work or not" check.

lz4: ensure length does not wrap ...

Note: this is the same as 206204a in
linux-git.

Given some pathologically compressed data, lz4 could possibly decide to
wrap a few internal variables, causing unknown things to happen.  Catch
this before the wrapping happens and abort the decompression.

lzo: properly check for overruns ...

Note: this is the same as 206a81c in

The lzo decompressor can, if given some really crazy data, possibly
overrun some variable types.  Modify the checking logic to properly
detect overruns before they happen.

net: add ENC28J60 support ...

ENC28J60 is a stand-alone Ethernet controller with SPI Interface
and integrated 10BASE-T PHY.

This driver was ported from linux-3.15.

The most notable barebox driver version changes:
  * add device tree support;
  * drop netif_msg_*() debug level checking;
  * use IF_ENABLED for checking CONFIG_ENC28J60_WRITEVERIFY;
  * add mii_bus support.

mii-tool: make the 'No MII transceiver present!' message more clear ...

Suppose you have two network controllers.
The first one is ENC28J60 (it is in low power mode
after start) the second one is always-enabled eth1.

As ENC28J60 is in low power mode before enc28j60_eth_open()
is called. ENC28J60's mii traceiver is in low power mode too
so the mii traceiver's register are inaccessable.

Here is a sample log just after barebox start:

  barebox:/ miitool
  miibus0: registered phy as /dev/phy0
    No MII transceiver present!.
  miibus1: registered phy as /dev/phy1
  phy1: eth1: negotiated 100baseTx-FD, link ok
  barebox:/ miitool
    No MII transceiver present!.
  phy1: eth1: negotiated 100baseTx-FD, link ok

The 'No MII transceiver present!.' message is confusing here.

This patch fixes the problem so the miitool output
looks like this:

  barebox:/ miitool
  phy0: spieth0:  No MII transceiver present!.
  phy1: eth1: negotiated 100baseTx-FD, link ok

menutree: let it select GLOB and GLOB_SORT ...

The menutree doesn't select CONFIG_GLOB, but it depends on it. Without
it will just hang. So let it select it automatically. Also remove the
dependency of CONFIG_GLOB on CONFIG_HUSH, because glob() will run with
the simple shell as well.

Also let CONFIG_MENUTREE select on CONFIG_GLOB_SORT. While is not
strictly needed, many people use menu/00-foo menu/10-bar menu/20-barf
to sort their menu entries. So select it out of convenience.

initcall we move this to a device initcall to get it out of
