Mark almost all Haskell ports for expiration by mid April

Ports for Haskell *libraries* are going to be removed from the ports tree.
Haskell *applications* are going to be statically linked with all dependencies
( https://reviews.freebsd.org/D19730  ), so there is no reason to keep
Haskell libraries in tree.

If you think a port is wrongly marked and should stay, please contact haskell@

lang/ghc: Update to 8.6.3 and bump PORTREVISION's of all Haskell ports.

As usual, it is recommended to rebuild or reinstall all the
dependent ports and the lang/ghc port itself in one of the following
ways:

# portmaster -w -r ghc
  or
# portupgrade -fr lang/ghc

In case of pkg(8), it is probably safer to remove all the GHC-dependent
packages along with GHC and reinstall everything from scratch.  For
example:

# pkg query "%ro" ghc > ghc-pkgs.txt
# pkg delete -y lang/ghc
# pkg install -y `cat ghc-pkgs.txt`

During update some hs-* ports got two PORTREVISION bumps in a row. Other ports
got a PORTVERSION update together with one PORTREVISION bump. This is caused
by bulk-bumping PORTREVISION of all hs-* ports. There are a lot of them updated,
so figuring out which ones require a bump and which are not is too tedious.
