Hi all again (view http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/120838)

First of all, I'm sorry for this my very long pr, and for posting
patches for five different ports, but this patchset is one only
thing, for how I imagined it and also all this port are maintained
by the same maintainers.

These patcheset address many different kind of problems.
But the two principal reasons for them are:

1) Building the hyperlinkable documentation of ghc
libraries directly, without to have to rebuild
ghc itself and so razoring the chicken-egg problem
for ghc/haddock/HsColour.

2) Solving the central problem for the port lang/ghc-doc
about the haddock interface files (the files *.haddock).
In fact these are architecture dependent and unless
this port doesn't supply with the right files for a
FreeBSD system, it's impossible to use these ones
to hyperlink the documentation with haddock.
At this moment, for example, the haddock interface files
lang/ghc-doc install are dos files. Another problem
of a binay port, like lang/ghc-doc, is that you have
to update, in any case, the registered paths for the
documentation if these are different from the standard
of the port lang/ghc.

I commit two patches for lang/ghc and devel/hs-haddock and
three new ports print/hs-hscolour, print/hs-hscolour-docs and
devel/hs-haddock-docs.

The solutions adopted are cheapest that I could imagine, and
don't break any update process with circular dependences:
for example to use a already installed version of haddock
to compile the documentation of ghc could break down this
process and I don't add it like an option.

A skeleton for these problems is this:

lang/ghc:

- A new knob WITH_DOCS is been introduced to install the user
  documentation and the hyperlinkable documentation, generated
  by haddock and HsColour.

- The problem of the hidden CONFIGURE_TARGET variable is been solved.

- The DOCSDIR is been changed.

- Now ghc knows about MANDIR and INFODIR.

- A man page of ghc will be installed, in any case.

- Also the DOCSDIR, with an subdirectory "cabal"  is been cabalised
  for the libraries documentation that, at this moment, no ghc
  related port installs. Actually no haskell port installs any
  documentation of their own libraries. This is a pity.

- A pkg-message.haddock about the problem of the HSghc
  libraries, related to the WITH_DOCS, is been add.

- The patch libraries-Cabal-Distribution-Simple-Haddock.hs is been
  added to correct a bug in Cabal (this patch is already in the last
  Cabal tree) related to HsColour and haddock (the patch is self
  explanatory).

devel/hs-haddock:

- It's been introduced the internal option SLAVE to install
  the lang/ghc with the hyperlinkable documentation.

- The option NOPORTDOCS is been eliminated, and the documentation
  is been delegated to the port devel/hs-haddock-docs.

- The DOCSDIR is been changed.

- The devel/readline dependence is been add, when the devel/readline
  port is been installed.

- The problem of an unregistered installation, using the package system, 
  is been correct. Also Installing a register.sh file permit to reregister
  haddock if, for example, ghc is deinstalled and reinstalled, without
  to have to reinstall haddock: lang/ghc is not a run dependency for the
  devel/haddock port.

The pkg-descr files are been integrated for both.

devel/hs-haddock-docs:

 - This port installs both the user documentation and the hyperlinkable
   documentation related to devel/hs-haddock, generated  by haddock
   and HsColour.

- The pkg-message related to the generating hyperlinkable documentation is
  been added.

print/hs-hscolour:

- hscolour is a small Haskell script to colourise Haskell
  code. It currently has four output formats: 

  ANSI terminal codes, HTML 3.2 with <font> tags,
  HTML 4.01 with CSS, and LaTeX.

- It's been introduced the internal option SLAVE to install
  the lang/ghc with the hyperlinkable documentation.

print/hs-hscolour-docs:

 - This port installs the hyperlinkable documentation related
   to print/hs-hscolour, generated  by haddock and HsColour.

 Haddock is a tool for automatically generating documentation from
 annotated Haskell source code. The documentation generated by Haddock
 is fully hyperlinked.
+Haddock can generate documentation in multiple formats; currently HTML
+is implemented, and there is partial support for generating DocBook.
