i2cdump: don't read block data in non-block modes

We currently read data twice in byte mode. Add a check to avoid calling
i2c_smbus_read_i2c_block_data() if we're not in I2C or SMBus block mode.

i2cdetect: fix address skipping in auto mode

If the bus doesn't support SMBus Quick Write or Receive Byte commands
and we're running in auto mode all addresses will be skipped resulting
in an empty table being printed.

This is caused by not restoring the auto mode after it's been changed
for certain address ranges - we need an additional variable to hold the
temporary state.

ash: allow popredir to be called if the stack is empty

If /tmp/test.sh is a script that tries to run a second script which
happens to be non-executable this:

   command . /tmp/test.sh

causes a seg fault.

This is because clearredir is called in the error path to clear the
stack of redirections.  The normal path then calls popredir, but popredir
fails when the stack is empty.

ash: fix EXEXEC status clobbering

evalcommand always clobbers the exit status in case of an EXEXEC
which means that exec always fails with exit status 2 regardless
of what it actually returns.

This patch adds the missing check for EXEXEC so that the correct
exit status is preserved.  It causes the test ash-misc/exec.tests
to succeed.

networking: add 'ip neigh' command

This patch ports the 'ip neigh' command, originally written by Alexey
Kuznetsov, <kuznet@ms2.inr.ac.ru>, to busybox.

The base of the port is the version of iproute that shipped with
Debian Squeeze, taken from:

  http://http.debian.net/debian/pool/main/i/iproute/iproute_20100519.orig.tar.gz

This patch has actively been used by the Open Network Install
Environment (ONIE) project for over 3 years without incident.
