New attribute 'no_protect_self'

With this attribute no deny rules are generated to protect interfaces
of a managed device. It is assumed that services of the device are
protected by other means.
This attribute is applicable to routers of model IOS, NX-OS and ACE.
New attr. strict_secondary, fixed local_secondary

With attribute strict_secondary, a device accepts only rules which
either are optimized secondary or are simple:
- protocol is IP,
- src and dst is either network, loopback interface
  or interface of managed device

An invalid local_secondary optimization was fixed.
This was shown in the new test case.
Fixed route for NX_OS: don't omit /32.

For NX_OS we generally create "i.i.i.i/32" instead of "host i.i.i.i"
now in access-lists and object-groups.
Added to Changes file.
