Always chdir() to current working directory.

chdir() to correct path after calling chroot()

Since chroot() doesn't chdir() by default, we are left in
an unreachable directory in node.pexec() (and in xterms.)

fixes #370

mnexec: mount sysfs in each container

The sysfs filesystem is [tagged][1] with a set of namespaces when mounted, taken
from the mounting process. Among other things, this controls which network
devices will show up in /sys/class/net and /sys/class/net/bonding_masters....

mnexec: getopt bugfix

getopt returns an 'int', so use change datatype of 'c' to match it.
Otherwise, 'c' may hold a value of 255 (0xff), and fail the comparison
with -1 (0xffffffff): while ((c = getopt(...)) != -1)

This bug was uncovered on Ubuntu 13.04 running on ARM, using...

Removed unused variable.

Support for control-C. Finally.

I've changed the way things work a bit:

1. netns is replaced by mnexec, a general-purpose mininet helper.

2. For interactive commands, we now use mnexec -p, which prints out
the pid, so we can kill it when someone hits control-C!...
