env: Add environment variable flags
Currently just validates variable types as decimal, hexidecimal, boolean, ip address, and mac address. If the entry is not found in the env ".flags", then look in the static one. This allows the env to override the static definitions, but prevents the need to have every definition in the environment distracting you. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
