Merging branch /nmap-exp/shinnok/nmap-options-parsing into trunk.

Browse Source 
Nmap delays parsing for options that require knowledge of other options that
the user might have supplied in order to make informed decisions. This is
achieved by using a temporary storage place in which options that can't be
correctly parsed and interpreted without having full knowledge of all other
user supplied command line arguments like -S and -6.
