Change the API of MArray to allow resizable arrays
See #704

The MArray class doesn't currently allow a mutable array to change its
size, because of the pure function

  bounds :: (HasBounds a, Ix i) => a i e -> (i,i)

  getBounds :: (MArray a e m, Ix i) => a i e -> m (i,i)

to the MArray class, and

  bounds :: (IArray a e, Ix i) => a i e -> (i,i)

to the IArray class.

The reason that bounds had to be incorporated into the IArray class is
because I couldn't make DiffArray work without doing this.  DiffArray
acts as a layer converting an MArray into an IArray, and there was no
way (that I could find) to define an instance of HasBounds for
DiffArray.

Add missing method genRange for StdGen (fixes #794)

MERGE TO STABLE

Trac #794 reports (correctly) that the implementation of StdGen
only returns numbers in the range (0..something) rather than
(minBound, maxBound), which is what StdGen's genRange claims.

This commit fixes the problem, by implementing genRange for StdGen
(previously it just used the default method).

Avoid strictness in accumulator for unpackFoldr

The seq on the accumulator for unpackFoldr will break in the presence of

an exception. This is a known issue with seq and rewrite rules that we

unpack/build on bytestrings seems to trigger a bug when interacting with

I'll investigate further, but best to disable this for now (its not

Note that with -frules-off or ghc 6.4.2 things are fine. It seems to
