      Subvert GHC's full-laziness optimisation by explicitly lambda-lifting
      a local lambda expression to the top level, and exporting it to ensure
      it doesn't get inlined.  Without this hack, full-laziness will float
      out several subexpressions, which turns out to be a pessimisation in
      this case.
      This is worth about 20% in hPutStr performance, so we now beat the old
      I/O library on 'cat' ;-)
      I'd like to MERGE TO STABLE this, but 5.02 is imminent so it might
      have to wait until 5.02.1.

      Fix a couple more cut-n-pastos in the line-buffered version of
      hPutStr.  Also fill in the export list while I'm here.

      Globally-uniquify the names of some _wrap functions so that the
      previously-undetected global namespace clashes don't cause an
      assertion failure in Hash.c when compiled -DDEBUG when starting GHCi
      with various hslibs packages.

      Don't use relative #include paths, as these files will be compiled from
      inside cbits (they're now linked into the cbits library). All paths on which
      include files may be found must now be given with -I directives.

      - System.exitWith now raises a (new) exception,
      	ExitException ExitCode.
      - While I was there I cleaned up System.getArgs and
        System.getProgName, using foriegn label and removing progargs.c

      I/O library rewrite
      This commit replaces the old C/Haskell I/O implementation with a new
      Haskell-only one using the new FFI & hsc2hs.
      main points:
         - lots of code deleted: we're about 3000 lines of C lighter,
           but the amount of Haskell code is about the same.
         - performance is ok: some operations are faster, others are
           slower.  There's still some tuning to do, though.
         - the new library is designed to handle read/write streams
           much better: a read/write stream gets a special kind of
           handle internally called a "DuplexHandle", which actually
           contains two separate handles, one for writing and one for
           reading.  The upshot is that you can do simultaneous reading
           and writing to/from a socket or FIFO without any locking
           problems.  The effect is similar to calling socketToHandle
           twice, except that finalization works properly (creating
           two separate Handles could lead to the socket being closed
           too early when one of the Handles is GC'd).
         - hConnectTo and withHandleFor are gone (no one responded to
           my mail on GHC users, but we can always bring 'em back if
         - I made a half-hearted attempt at keeping the system-specific
           code in one place: see PrelPosix.hsc.
         - I've rearranged the I/O tests and added lots more.
           ghc/tests/lib/IO now contains Haskell 98-only IO tests,
           ghc/test/lib/{IOExts, Directory, Time} now contain tests for
           the relevant libraries.  I haven't quite finished in here yet,
           the IO tests work but the others don't yet.
         - I haven't done anything about Unicode yet, but now we can
           start to discuss what needs doing here.  The new library
           is using MutableByteArrays for its buffers because that
           turned out to be a *lot* easier (and quicker) than malloc'd
           buffers - I hope this won't cause trouble for unicode
           translations though.
      WARNING: Windows users refrain from updating until we've had a chance
      to fix any issues that arise.
      Testing: the basic H98 stuff has been pretty thoroughly tested, but
      the new duplex handle stuff is still a little green.
