This commit fixes many bugs and limitations in the threaded RTS.
There are still some issues remaining, though.

The following bugs should have been fixed:

- [+] "safe" calls could cause crashes
- [+] yieldToReturningWorker/grabReturnCapability
    -     It used to deadlock.
- [+] couldn't wake blocked workers
    -     Calls into the RTS could go unanswered for a long time, and
          that includes ordinary callbacks in some circumstances.
- [+] couldn't block on an MVar and expect to be woken up by a signal
      handler
    -     Depending on the exact situation, the RTS shut down or
          blocked forever and ignored the signal.
- [+] The locking scheme in RtsAPI.c didn't work
- [+] run_thread label in wrong place (schedule())
- [+] Deadlock in GHC.Handle
    -     if a signal arrived at the wrong time, an mvar was never
          filled again
- [+] Signals delivered to the "wrong" thread were ignored or handled
      too late.

Issues:
*) If GC can move TSO objects (I don't know - can it?), then ghci
will occasionally crash when calling foreign functions, because the
parameters are stored on the TSO stack.

*) There is still a race condition lurking in the code
(both threaded and non-threaded RTS are affected):
If a signal arrives after the check for pending signals in
schedule(), but before the call to select() in awaitEvent(),
select() will be called anyway. The signal handler will be
executed much later than expected.

*) For Win32, GHC doesn't yet support non-blocking IO, so while a
thread is waiting for IO, no call-ins can happen. If the RTS is
blocked in awaitEvent, it uses a polling loop on Win32, so call-ins
should work (although the polling loop looks ugly).

*) Deadlock detection is disabled for the threaded rts, because I
don't know how to do it properly in the presence of foreign call-ins
from foreign threads.
This causes the tests conc031, conc033 and conc034 to fail.

*) "safe" is currently treated as "threadsafe". Implementing "safe" in
a way that blocks other Haskell threads is more difficult than was
thought at first. I think it could be done with a few additional lines
of code, but personally, I'm strongly in favour of abolishing the
distinction.

*) Running finalizers at program termination is inefficient - there
are two OS threads passing messages back and forth for every finalizer
that is run. Also (just as in the non-threaded case) the finalizers
are run in parallel to any remaining haskell threads and to any
foreign call-ins that might still happen.

- Generalise seq to allow an unlifted type in its second argument.  This
  works because seq is *always* inlined and replaced by a case.

- Remove getTag, a wired-in Id with an unfolding, with a definition
  in GHC.Base:

getTag x = x `seq` dataToTag# x

  this is why we required the above generalisation to seq (dataToTag#
  returns an Int#).  See the comments in GHC.Base for more details.

- As a side-effect, this fixes a bug in the interpreter, where the
  compiler optimised away the evaluation of the argument to dataToTag#,
  but the interpreter ended up passing it an unevaluated thunk (nullary
  constructors aren't always evaluated in GHCi, but the simplifier
  assumes they are).  Now, in the interpreter, getTag won't be inlined
  so the compiler can't optimise away the evaluation, and we're saved.

  The real bug here is either (a) dataToTag# requires an evaluated
  argument or (b) the interpreter doesn't supply it with one, take your
  pick.

The big change here is that it is no longer necessary to explicitly
say '-package X' on the command line if X is a package containing
hierarchical Haskell modules.  All packages marked "auto" contribute
to the import path, so their modules are always available.  At link
time, the compiler knows which packages are actually used by the
program, and it links in only those libraries needed.

There's one exception: one-shot linking.  If you link a program using

    ghc -o prog A.o B.o ...

then you need to explicitly add -package flags for each package
required (except base & haskell98) because the compiler has no
information about the package dependencies in this case.

Package configs have a new field: auto, which is either True or False.
Non-auto packages must be mentioned on the command-line as usual.
Non-auto packages are still required for:

  - non-hierarchical libraries (to avoid polluting the module namespace)

  - packages with no Haskell content

  - if you want more than one version of a package, or packages

Changes to the exception interface, as discussed on the libraries list.

1) Move bracket and bracket_ from GHC.Exception (and hence System.IO)
   to haskell98/IO.hs.  These two should now never be used (except in
   all-H98 programs), and this will save users of the new libraries from
   having to hide them.  Use the ones in Control.Exception instead.

2) Define

        type IOError = IOException      -- was Exception

   leaving the type of Prelude.ioError as IOError -> IO a,
   but adding to Control.Exception

        throwIO :: Exception -> IO a

The result is a type distinction between the variants of catch and try:

Prelude.catch           :: IO a -> (IOError -> IO a) -> IO a
Control.Exception.catch :: IO a -> (Exception -> IO a) -> IO a
System.IO.Error.try     :: IO a -> IO (Either IOError a)
Control.Exception.try   :: IO a -> IO (Either Exception a)

These are breaking changes: the first one affects only import lists,
but the second will bite in the following situations:

- using ioError on general Exceptions: use throwIO instead.

- using throw on IOErrors: if in the IO monad, use ioError instead.
  Otherwise, use throw (IOException e), but why are you throwing
  IO exceptions outside of the IO monad?

Minor changes:
- System.IO.Error now exports catch and try
- moved try from GHC.Exception to System.IO.Error, because it's
  portable and can be shared by Hugs.

can make out has been there for ever.  Presumably no-one uses this
abstraction...

The bug is that waitQSemN would discard any other blocked threads
(presumably waiting for a larger chunk of the semaphore) if it
succeeds.

It still looks to me like the quantity semaphores in here can suffer
from starvation: if one thread requests a large chunk, while lots of
other threads are requesting smaller chunks, then the thread
requesting the large chunk might never get to run.  I'm sure this must
be a well-known problem.

Merge Fix.hs with MonadRec.hs, and remove the latter.

As agreed, the class is now called "MonadFix", and the
library is called "Control.Monad.Fix".

Note: The old Control.Monad.Fix used to export the function

      fix :: (a -> a) -> a

I retained that behavior, but I don't think it should export it.

The MonadRec.hs library, stolen from the Hugs release.

Note: There's a clear overlap with the library Control.Monad.Fix.

      Unfortunately, the names of the classes are different, mainly
      for historical reasons (MonadFix vs MonadRec.) There was some
      discussion on how to resolve this a while back, but I guess
      Hugs and GHC went their own ways. Once the dust settles, we
      can agree on something common, and make Hugs and GHC use the same
      names. (Note that this duplication also exists in the current
      release of Hugs as well.) For the time being, this file helps
      keep things simple with regard to the already existing code
      that uses the mdo-notation.. (i.e., it also defines instances
      for the LazyST, ST, and list monads in addition
      to the ones defined in Fix.hs: IO and maybe.)

We can also name this file just "Rec", but "MonadRec" sounds less
confusing, and more inline with the Hugs release.

(Hugs only) conform to the current FFI spec.  This code makes the
additional assumption that a finalizer added with addForeignPtrFinalizer
runs before any existing finalizers on the same object.
