update on ghc-7.8 building

[Jens Petersen]

Hi,

In the last week I went through Ricky's ghc-7.8 rebuild results with current rawhide
and fixed/updated many packages: you may have seen commits for some of the packages flow by...

Currently there are some Fedora packages that still can't build with ghc-7.8
- mostly because of new dependencies required:

- Agda: needs 4 new packages
  - STMonadTrans, boxes, data-hash, equivalence (all not yet submitted)
- cab: needs process-conduit or conduit-extra
- ForSyDe: compile errors
- MonadCatchIO-transformers: needs monads-tf
  - blocks snap-core -> snap-server -> hakyll
- hledger: needs tabular and wizard
- haddock: type error
  - blocks leksah-server and leksah
- wai-extra: needs monad-loops and stm-chans
  - I have committed wai/warp 3.0 stack 
- scotty: needs conduit-1.1 or wai-2.0
- shake: test failure (can disable tests once reported)
- type-level: needs parameterised-data
- hedgewars: *block* not in scope

I deprecated: cabal-dev, ghc-xhtml, ghc-terminfo, and ghc-haskeline

If people could help by reviewing:

monads-tf: https://bugzilla.redhat.com/show_bug.cgi?id=1135933
monad-loops: https://bugzilla.redhat.com/show_bug.cgi?id=1135874
stm-chans: https://bugzilla.redhat.com/show_bug.cgi?id=1135867
http-date: https://bugzilla.redhat.com/show_bug.cgi?id=1135906

that would be much appreciated.

So far I have basically addressing build failures:
there are still many more packages that can be updated.
