Switch over to the new hierarchical libraries
---------------------------------------------
This commit reorganises our libraries to use the new hierarchical
module namespace extension.
The basic story is this:
- fptools/libraries contains the new hierarchical libraries.
Everything in here is "clean", i.e. most deprecated stuff has
been removed.
- fptools/libraries/base is the new base package
(replacing "std") and contains roughly what was previously
in std, lang, and concurrent, minus deprecated stuff.
Things that are *not allowed* in libraries/base include:
Addr, ForeignObj, ByteArray, MutableByteArray,
_casm_, _ccall_, ``'', PrimIO
For ByteArrays and MutableByteArrays we use UArray and
STUArray/IOUArray respectively now.
Modules previously called PrelFoo are now under
fptools/libraries/GHC. eg. PrelBase is now GHC.Base.
- fptools/libraries/haskell98 provides the Haskell 98 std.
libraries (Char, IO, Numeric etc.) as a package. This
package is enabled by default.
- fptools/libraries/network is a rearranged version of
the existing net package (the old package net is still
available; see below).
- Other packages will migrate to fptools/libraries in
due course.
NB. you need to checkout fptools/libraries as well as
fptools/hslibs now. The nightly build scripts will need to be
tweaked.
- fptools/hslibs still contains (almost) the same stuff as before.
Where libraries have moved into the new hierarchy, the hslibs
version contains a "stub" that just re-exports the new version.
The idea is that code will gradually migrate from fptools/hslibs
into fptools/libraries as it gets cleaned up, and in a version or
two we can remove the old packages altogether.
- I've taken the opportunity to make some changes to the build
system, ripping out the old hslibs Makefile stuff from
mk/target.mk; the new package building Makefile code is in
mk/package.mk (auto-included from mk/target.mk).
The main improvement is that packages now register themselves at
make boot time using ghc-pkg, and the monolithic package.conf
in ghc/driver is gone.
I've updated the standard packages but haven't tested win32,
graphics, xlib, object-io, or OpenGL yet. The Makefiles in
these packages may need some further tweaks, and they'll need
pkg.conf.in files added.
- Unfortunately all this rearrangement meant I had to bump the
interface-file version and create a bunch of .hi-boot-6 files :-(

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
necessary).
- 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.
