Refactoring for derived Read

There are no functional changes in this commit.  But the code for
derived Read is refactored to make it tidier --- and also to make
it very easy if we want derived Read to parse the prefix form of
infix ocnstructors.

For example,
data T = Int `T1` Int
According to the H98 report, the derived Read instance will parse
infix uses of T1, but not prefix uses (T1 4 3).  It's arguable that it
should parse both -- and easy to implement, but it would cause a little bit
of code bloat.

to do so.

Simon Marlow [Thu, 24 Aug 2006 11:49:02 +0000 (11:49 +0000)]
divide packages into "core" and "extra" packages
The following packages are now "core" packages:

  base, Cabal, haskell98, readline, regex-base, regex-compat
  regex-posix, stm, template-haskell, unix, Win32

Core packages are those packages required to bootstrap GHC, or are
closely tied to GHC (stm, template-haskell).  These are the packages
that will be provided in a source distribution from now on.

All other packages are classified as "extra" packages.  As far as
binary distributions and nightly builds go, nothing will change -
we'll still build and include all these packages in the distributions.

NOTE: 'sh darcs-all get' will now get the core packages only.  To get
the extra packages too, use 'sh darcs-all --extra get'.
