The parsePackageIndex wasn't streaming because resulting list was
hidden in two constructors: Either and tuple. By removing that error
semantics changed in updatePackageIndexCacheFile.

The updatePackageIndexCacheFile problem was sequence call that evaluated
whole list made by parsePackageIndex. By using lazySequence any error
during index file parsing will be raised during writing to cache file.

Also removed reacPackageIndexFile, as it wasn't used anywhere as far as
I can tell. If this is a mistake I'll include it again.

Instead of:
C:\Users\Ganesh\AppData\Local\Temp\data-default-instances-old-locale-0.0.1-11924\data-default-instances-old-locale-0.0.1
(which was the case before @ezyang's patch)
we now get:
C:\Users\Ganesh\AppData\Local\Temp\cabal-tmp-11924\data-default-instances-old-locale-0.0.1

Fixes #2658.

Only warn for missing Setup.hs if build type isn't Simple

Because cabal sdist will add a default Setup.hs anyway

Instead of:
C:\Users\Ganesh\AppData\Local\Temp\data-default-instances-old-locale-0.0.1-11924\data-default-instances-old-locale-0.0.1
we get:
C:\Users\Ganesh\AppData\Local\Temp\data-default-instances-old-locale-0.0.1-11924

Instead of:
dist\build\libHSdata-default-instances-old-locale-0.0.1-6jcjjaR25tK4x3nJhHHjFM.a-11924\libHSdata-default-instances-old-locale-0.0.1-6jcjjaR25tK4x3nJhHHjFM.a
we get:
dist\build\objs-11924\libHSdata-default-instances-old-locale-0.0.1-6jcjjaR25tK4x3nJhHHjFM.a

This should put us under the limit.

These were dropped during the migration to github.  This patch restores
them, but note that they do not all pass!

Ignore tags when parsing version numbers

Allow using cabal program itself as the external setup method

This fixes issues when the version of Cabal that cabal-install was built
against differs from the one registered in the local package DB. Normally
we compile an external setup against the local Cabal library, which could
lead to failures or inconsistent results compared to using the internal
method.

This fixes #2438 and fixes #1938.

No change to the syntax, old tags syntax allowed but simply ignored.

Version tags have been deprecated for years and are disappearing from
the Version type in base soon.

We previously recorded the canonical package and the instance of a link group
separately, but it turns out we can always record these together: when we know
one we know the other. This makes various choices a lot clearer.
