2nd deprecation campaign

[Baptiste Daroussin]

Hi all,

I am in the middle of a new deprecation campaign, to remove ports
where no more distfiles are publicly available (no other OS mirrors
doesn't count except if they are the upstream of course).

Maybe some will be false positive (I will try to not have too much of them).

Do not hesitate to manifest and undeprecate ports that would have
deprecated by mistake. Even better do not hesitate to propose yourself
to maintain them.

Thanks,
Bapt
