Extend hConnectTo to also allow output handles to be connected, i.e.,
h1 <- openFile "foo" WriteMode
h2 <- openFile "bar" WriteMode
hConnectTo h1 h2
will cause h1's buffer to be flushed when h2's buffer overflows
(and it is just about to be flushed.) The implementation is currently
not as lazy as that, it flushes h1's buffer regardless of whether h2's
buffer overflows or not.
This is used to connect 'stderr' and 'stdout', i.e., output on
'stderr' will now cause 'stdout' output to (first) be flushed.

Library re-organisation:
All libraries now live under ghc/lib, which has the following structure:
ghc/lib/std -- all prelude files (libHS.a)
ghc/lib/std/cbits
ghc/lib/exts -- standard Hugs/GHC extensions (libHSexts.a)
-- available with '-fglasgow-exts'
ghc/lib/posix -- POSIX library (libHSposix.a)
ghc/lib/posix/cbits -- available with '-syslib posix'
ghc/lib/misc -- used to be hslibs/ghc (libHSmisc.a)
ghc/lib/misc/cbits -- available with '-syslib misc'
ghc/lib/concurrent -- Concurrent libraries (libHSconc.a)
-- available with '-concurrent'
Also, several non-standard prelude modules had their names changed to begin
with 'Prel' to reduce namespace pollution.
Addr ==> PrelAddr (Addr interface available in 'exts')
ArrBase ==> PrelArr
CCall ==> PrelCCall (CCall interface available in 'exts')
ConcBase ==> PrelConc
GHCerr ==> PrelErr
Foreign ==> PrelForeign (Foreign interface available in 'exts')
GHC ==> PrelGHC
IOHandle ==> PrelHandle
IOBase ==> PrelIOBase
GHCmain ==> PrelMain
STBase ==> PrelST
Unsafe ==> PrelUnsafe
UnsafeST ==> PrelUnsafeST
