[Freeciv-Dev] (PR#9324) startunits and sea units

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

Startunits will put sea units on the land.  Sometimes they can be 
totally landlocked, and will never be able to move.

Fixing this seems very tricky.  Currently all starting positions are put 
on land.  We're not guaranteed to have a sea position within the 
dispersion radius.  However if sea units are present there's a good 
chance we'd have enough of them to transport all starting land units. 
In that case a starting position could be placed on the ocean, and the 
land unit(s) could be put inside the sea unit(s).  But this may be very 
hard, because the starting positions may be generated before the server 
option is even set (I think).

In the short term I think the only viable solution is to remove the sea 
unit roles from the possible starting units.  This doesn't prevent other 
sea units from being given the other starting-unit roles, though.
