and fix bug in qualityDeps

Run cabal-install unit tests on AppVeyor

See https://github.com/haskell/cabal/pull/3155#issuecomment-185888195.

Improve the 'getModTime' implementation.

Pass 'ghc-shared-options' to GHC during the linking phase.

D.PD.Check: Also check 'ghc-shared-options'.

See discussion in #3158.

In addition to 'ghc-options' and 'ghc-prof-options'. Some people specify '-fprof
-auto-all' there.

Two changes:

  * 'getModTime' now uses 'modificationTimeHiRes' instead of 'modificationTime'
    on Unix when the former is available.

  * 'ModTime' is now represented as a 64-bit unsigned integer in Windows UTC
    format (that is, 100 ns resolution and day zero is 1601-01-01) on all
    platforms. Previously we used POSIX seconds, which was wrong (low
    resolution). Sandbox timestamp files in old format are now up-converted on
    the fly.

Fixes #3132.

Fix bug #3150, regression introduced by a2184538.

Added tests for this case, as well as some more.  This
probably breaks the Windows build.
