bump version to 3.00

- remove Ghc2_0
- bump GHC version number to 3.00
- default compiler to build with is 2.10

protect an import with #ifdef DEBUG.

add hints about checking out extra bits into an existing tree.

LoopHack not needed anymore.

startPerformIO: push realWorld# token on the B stack now.

Removed support for picking up plausible source file
names inside the ghc options chunk of the command
line. It failed to deal with `option-value' stuff present
on some invocations of ghc (e.g., "-ohi foo.baz").

Add missing file from Multi-param merge.

The Great Multi-Parameter Type Classes Merge.

Notes from Simon (abridged):

* Multi-parameter type classes are fully implemented.
* Error messages from the type checker should be noticeably improved
* Warnings for unused bindings (-fwarn-unused-names)
* many other minor bug fixes.

Internally there are the following changes

* Removal of Haskell 1.2 compatibility.
* Dramatic clean-up of the PprStyle stuff.
* The type Type has been substantially changed.
* The dictionary for each class is represented by a new
  data type for that purpose, rather than by a tuple.

Added an overview section, commented out some of the more bogus parts of the document (but some bits still remain)

add nofib/GHC_ONLY/array002 to the array test suite.

Add numeric tests from nofib/GHC_ONLY.

I was *sure* I'd removed these before...

protect part of the binary-dist rules against 'for i in ; do ...'.

patch level 1

Some shells have problems with 'for i in ; do ...', so protect the
relevant for loops with 'if test <string>; then ...'.

Replace three 'test ... && ...' sequences with 'if ... then ... fi',
since the test form would fail, causing some non-GNU makes to bomb
out (maybe they invoke sh with -e?).

compile simplStg/UpdAnal.lhs with -fno-strictness until the strictness
analyser bug is fixed.

portabilify a test.

remove some superfluous-looking parenthesis around a test.

fix a couple of typos.

remove support for using the Happy from the tree.

reinforce the test for Happy: version 1.4 or later is now *required*

put note about Happy being separated out.

add a .sgml->.tex rule

fix for the getWorkerIdAndCons bug.

add a few more change notes.

print idinfo with a BigCoreBinder.

a few changes to the 2.10 announcement

use PACKAGE_BINS to get the actual binaries to install.

set GhcBinDistBins.

add PACKAGE_BINS for a binary_dist.

don't split objects for way "mr" too.

bump a few heap sizes to be on the safe side.

hi file comes out on stderr, not stdout.

add test for getWorkerIdAndCons bug.

Move array tests from ghc/lib to ghc/tests and put them in our test
framework.

add subdirectory 'array'.

Move array tests from ghc/lib to ghc/tests and put them in our test
framework.
