Add vlan configuration support to etherswitchcfg.

This adds the support to the config keyword (vlan operation mode), ports
flags, prints the vlan mode and vlan capabilities. It also adds some basic
information to usage() and support the keyword 'help' as a shortcut to
usage(). The manual page is also updated with the new options.
