[svn-r11780] Purpose:

Added high-level example directories

Description:
Refactored common code out of examples Makefiles.am, added high-level
example directories, added packet table examples.

Solution:
Examples now draw from a common config/examples.am file, which
contains rules for installing, uninstalling, and cleaning examples.
High-level example directories are mostly empty, except for the
C and C++ packet table tests.

Platforms tested:
mir, sleipnir, copper, shanti
