In preparation for parallel GC, split up the monolithic GC.c file into
smaller parts. Also in this patch (and difficult to separate,
unfortunatley):
- Don't include Stable.h in Rts.h, instead just include it where
necessary.
- consistently use STATIC_INLINE in source files, and INLINE_HEADER
in header files. STATIC_INLINE is now turned off when DEBUG is on,
to make debugging easier.
- The GC no longer takes the get_roots function as an argument.
We weren't making use of this generalisation.

We had
base=01100000 size=1048576 size_delta=0 it->size=2097152
it->base=00F00000 base-it->base=00200000
in commitBlocks.
Esa Ilari Vuokko identified this inequality test as the cause.

Some of the memory allocation calls were being checked for error, but
the RTS was printing a message and continuing. These error cases
lead to crashes later, so better to just fail immediately.

A simple interface for generating trace messages with timestamps and
thread IDs attached to them. Most debugging output goes through this
interface now, so it is straightforward to get timestamped debugging
traces with +RTS -vt. Also, we plan to use this to generate
parallelism profiles from the trace output.

Most of the other users of the fptools build system have migrated to
Cabal, and with the move to darcs we can now flatten the source tree
without losing history, so here goes.
The main change is that the ghc/ subdir is gone, and most of what it
contained is now at the top level. The build system now makes no
pretense at being multi-project, it is just the GHC build system.
No doubt this will break many things, and there will be a period of
instability while we fix the dependencies. A straightforward build
should work, but I haven't yet fixed binary/source distributions.
Changes to the Building Guide will follow, too.
