tarballs if these tarballs are already present.

A couple of settings were filtered out since
74cb2909 including
`configure-option`. However, it turns out you may want to
persist some options to `configure`, such as e.g.

  --configure-option=--build=x86_64-w64-mingw32

when working in a Cygwin host environment, but using a Mingw
toolchain (such as the one bundled with the Windows GHC bindist).

'[drop,take]WhileEnd p' is semantically the same as 'reverse . [drop,take]While
p . reverse', but more efficient and easier to read.

"-czf" must go first.

'Setup.hs sdist': invoke 'tar' with '--format ustar' if possible.

Fixes #1901. Some variants of 'tar' don't support the '--format' option, so we
have to do feature detection.

Note that 'cabal sdist' (as opposed to 'Setup.hs sdist') uses the built-in
tar.gz archiver ('Distribution.Client.Tar') and doesn't invoke 'tar' or 'gzip'.

System.Win32.DLL import seems redunant

This reverts commit f59bab10.

Revert "Switch InstallPlan over to using IPID-indexed PackageIndex."

This reverts commit 6465d174.

1. When we union PackageIndexes together, prefer the later one.
   This idiom is used when we update the processing-state of
   packages in an InstallPlan.

2. dependencyInconsistencies' was missing a number of indirections
   through the fakeMap, so in some cases we incorrectly concluded
   packages were not equal when they were.

3. We need to initialize the fakeMap with any pre-installed packages,
   otherwise the invariant check for configured-packages will fail.

Switch InstallPlan over to using IPID-indexed PackageIndex

This works around GHC bug #8942, for the versions of GHC which are
affected by this bug.

Stop repeated rebuilds on Travis

Changing the build config format causes cabal-install to repeatedly
rebuild the Cabal library during the configure->build->test cycle.

bootstrap: fix network vsn regex typo

NETWORKURI_VER_REGEXP should be NETWORK_URI_VER_REGEXP

Support module thinning and renaming Cabal-side.

Travis failure is due to https://github.com/haskell/cabal/issues/2114

Unlike GHC, Cabal will still try to find a globally consistent choice for
all package names, i.e. this does *not* implement private dependencies.

Allow random-1.1

Update bootstrap.sh

This fixes issue #1945 and replaces pull request #1947.

These bugs in #1947 are fixed:
* The pull request no longer applied cleanly to master because of the
  Binary LocalBuildInfo patches.
* The new test cases did not put the generated HPC interface files under
  "dist/", so the files weren't cleanup up correctly.
* HPC interface files for each component need to be separated, but the
  were being combined into the same directory.

These enhancements are also implemented:
* Program coverage is now used for all components when enabled and the
  flag --enable-library-coverage has been changed to --enable-coverage.
* A helpful error message is printed if the obsolete flag
  --enable-library-coverage is used.
