This moves all URL references to Trac Wiki to their corresponding
GitLab counterparts.
This substitution is classified as follows:
1. Automated substitution using sed with Ben's mapping rule [1]
Old: ghc.haskell.org/trac/ghc/wiki/XxxYyy...
New: gitlab.haskell.org/ghc/ghc/wikis/xxx-yyy...
2. Manual substitution for URLs containing `#` index
Old: ghc.haskell.org/trac/ghc/wiki/XxxYyy...#Zzz
New: gitlab.haskell.org/ghc/ghc/wikis/xxx-yyy...#zzz
3. Manual substitution for strings starting with `Commentary`
Old: Commentary/XxxYyy...
New: commentary/xxx-yyy...

This is a preparation for #16295: https://ghc.haskell.org/trac/ghc/ticket/16295
This commit mostly focuses on getting rid of untracked dependencies,
which prevent Shake's new `--shared` feature from appropriately caching
build rules.
There are three different solutions to untracked dependencies:
* Track them! This is the obvious and the best approach, but in some
situations we cannot use it, for example, because a build rule creates
files whose names are not known statically and hence cannot be
specified as the rule's outputs.
* Use Shake's `produces` to record outputs dynamically, within the rule.
* Use Shake's `historyDisable` to disable caching for a particular build
rule. We currently use this approach only for `ghc-pkg` which mutates
the package database and the file `package.cache`.
These two tickets are fixed as the result:
Ticket #16271: https://ghc.haskell.org/trac/ghc/ticket/16271
Ticket #16272: https://ghc.haskell.org/trac/ghc/ticket/16272 (this one
is fixed only partially: we correctly record the dependency, but we
still copy files into the RTS build tree).

cabal introduces SPDX identifier, and as such we need to change the
BSD3 license name. Also the >= qualifier is no longer prefered.

Adding cabal files to `unlit`, `touchy` and `hp2ps`, allows us to treat
them uniformally across the build system. In particular Hadrian will use
these.

Summary:
Remove some Windows specific code from the .m4 files
and have configure figure it out.
Unfortunately touchy can't be removed since there
is no mingw build of coreutils. Only msys builds
which would give us a dependency on the msys runtime.

Simplify some preprocessor expressions involving `_MSC_VER` because
`_WIN32` is always defined when `_MSC_VER` is.

In Haskell files, replace `__MINGW32__` by `mingw32_HOST_OS`.
In .c and .h files, delete `__MINGW32__` when `_WIN32` is also tested
because `_WIN32` is always defined when `__MINGW32__` is. Also replace
`__MINGW32__` by `_WIN32` when used standalone for consistency.

We now define _PROGNAME, and _PROG is automatically defined with
$(exeext). This will shortly automatically use the right exeext
depending on what stage it is being compiled with (exeext may be
different for different stages when cross-compiling).

It's now simpler, and it fails if something fails rather than just
printing an error message and continuing.

With Windows 7 in a vitrual box VM on OS X, some very odd things happen
with dates and time stamps when SSHing into cygwin. e.g. here the
"Change" time is in the past:
$ date; touch foo; stat foo
Fri Dec 2 16:58:07 GMTST 2011
File: `foo'
Size: 0 Blocks: 0 IO Block: 65536 regular
empty file
Device: 540aba0bh/1409989131d Inode: 562949953592977 Links: 1
Access: (0644/-rw-r--r--) Uid: ( 1000/ ian) Gid: ( 513/ None)
Access: 2011-12-02 16:58:07.414457900 +0000
Modify: 2011-12-02 16:58:07.414457900 +0000
Change: 2011-12-02 16:58:03.495141800 +0000
Birth: 2011-12-02 16:57:57.731469900 +0000
And if we copy such a file, then the copy is older (as determined by the
"Modify" time) than the original:
$ date; touch foo; stat foo; cp foo bar; stat bar
Fri Dec 2 16:59:10 GMTST 2011
File: `foo'
Size: 0 Blocks: 0 IO Block: 65536 regular

This means that make thinks that things are out of date when it
shouldn't, so reinvokes itself repeatedly until the MAKE_RESTARTS
infinite-recursion test triggers.
The touchy program, like most other programs, creates files with both
Modify and Change in the past, which is still a little odd, but is
consistent, so doesn't break make.

Bindists should now work again, when doing "make install" at least.
"make in-place" is probably still broken.

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.
