    libnetmap: remove interface name validation
    
    When trying to use a VLAN device (e.g. "em0.123") with a dot
    the library fails to parse the interface correctly. The former
    pattern is much too restrictive given that almost all characters
    can be coerced into a device name via ifconfig.
    
    Remove the particularly restrictive validation.  Some characters
    still cannot be used as an interface name as they are used as
    delimiters in the syntax, but this allows to be able to use most
    of them without an issue.
