This function will format a MAC address as colon-separated hex bytes.
It's really very simple: stdnse.tohex(mac, {separator=":"})
This commit updates all the instances I could find of the varying
convoluted attempts at performing this conversion.
Similar changes to r30653, but may break compatibility with people using
integer millisecond values, which are now treated as number of seconds.
To get same behavior, use ms after number, e.g. 5000 becomes 5000ms or
5s
Many scripts were documented as using timespecs (10s, 5000ms, etc) for
timeout script-args, but one 1 or 2 actually did. Now all timeout
script-args will accept timespecs, except those which took a number of
milliseconds, which remain unchanged.
Also fixed some documentation issues (missing script name in arg
description, missing nsedoc for args, etc)
