This includes a fix to silence a GCC warning which causes validate failures
on OSX (see haskell/primitive#4 for more details)

Cabal was already updated to 1.18.1.2. last month, but then got reverted
by accident by 06aac68d

There are three core changes here:

a) In the constraint-solver pipeline.
   Given a work-item 'wi', the old scheme was:
      let relevant = getRelevantInerts wi
      interact 'wi' with each constraint in 'relevant'
   Bu now we have a single step
      interact 'wi' with the inert-set

   This turns out to avoid duplication, between getRelevantInerts
   (which needs to know which are relevant) and the interact step.
   Simpler, cleaner.

   This in turn made it sensible to combine the 'spontaneous solve'
   stage into the 'interact with inerts' stage.

b) Wanteds are no longer used to rewrite wanteds.  See Trac #8450.
   This in turn means that the inert set may have
     - many CFunEqCans with the same LHS
     - many CTyEqCans  with the same LHS
   Hence the EqualCtList in teh domain of inert_eqs and inert_funeqs

c) Some refactoring of the representation of the inert set,
   Notably inert_dicts and inert_funeqs are indexed by Class and TyCon
   respectively, so we can easily get all the constraints relevant to
   that class or tycon

There are many knock on effects!  This started as a small job but I
ended up doing qite a lot.  Some error messages in the test suite
really did improve as a result of (b)

This contains the Haskeline commit fixing #7768

Thus GHC's in-tree version corresponds exactly to
[hackage:terminfo-0.3.2.6]. Morever, `terminfo` has moved
to GitHub as well (https://github.com/judah/terminfo

) so
the upstream repo URL in `packages` is updated as well.

This is actually a no-op wrt the source-code and is only performed to show
that upstream is identical to our lagged repository.

This is mainly to relax the `array` build-dep to
allow the upcoming `array-0.5.0.0` package.

 - `primitive` is updated to upstream's HEAD which is essentially
   `primitive-0.5.1.0`, plus a core-lint-error workaround for #8355 and
   some minor cleanups.

 - `vector` is updated to upstreams `vector-0.10.9.1` release

Note: The upstream repo location has changed to GitHub,
      hence the update in the `packages` file

In 6579a6c7 we removed existing comparison primops and introduced new ones
returning Int# instead of Bool. This commit (and associated commits in
array, base, dph, ghc-prim, integer-gmp, integer-simple, primitive, testsuite and
template-haskell) restores old names of primops. This allows us to keep
our API cleaner at the price of not having backwards compatibility.

This patch also temporalily disables fix for #8317 (optimization of
tagToEnum# at Core level). We need to fix #8326 first, otherwise
our primops code will be very slow.

The new commits inlcude AMP-warning fixes and support
for the new `instance Data Data.Version` provided by `base`

This is related to #8121

(+ 3 outstanding local patches)

(+ local fix for PolyTypeable)

This reverts commit 6df74382.

I didn't notice that rebase did not update submodules. Fixing now.

This also folds the new upstream repo at Github into GHC's `bytestring` Git
repo, so that we can directly track upstream from there in the future.

Apart from bumping build-dep version bounds, `ghc-cabal` is adapted to
some minor Cabal API changes, and `bin-package-db` is made aware of
Cabal's recently added AGPL licence support.

This fixes a build failure for i386/Windows.

This patch modifies all comparison primops for Char#, Int#, Word#, Double#,
Float# and Addr# to return Int# instead of Bool. A value of 1# represents True
and 0# represents False. For a more detailed description of motivation for this
change, discussion of implementation details and benchmarking results please
visit the wiki page: http://hackage.haskell.org/trac/ghc/wiki/PrimBool

There's also some cleanup: whitespace fixes in files that were extensively edited
in this patch and constant folding rules for Integer div and mod operators (which
for some reason have been left out up till now).

This reverts commit 0b72347d.
