vectorise: Put it out of its misery

Poor DPH and its vectoriser have long been languishing; sadly it seems there is
little chance that the effort will be rekindled. Every few years we discuss
what to do with this mass of code and at least once we have agreed that it
should be archived on a branch and removed from `master`. Here we do just that,
eliminating heaps of dead code in the process.

Here we drop the ParallelArrays extension, the vectoriser, and the `vector` and
`primitive` submodules.

-%%% Acknowledegments ==========================================================
-%%%
-%%% Thanks to Gabriele Keller <keller@it.uts.edu.au> for beta testing and
-%%% code contributions.  Thanks to the LaTeX3 project for improving the LaTeX
-%%% sources (which helped me writing this code).  Furthermore, I am grateful
-%%% to Martin Erwig <Martin.Erwig@FernUni-Hagen.de> and Bernard J. Pope
-%%% <bjpop@cs.mu.OZ.AU> for feedback and suggestions, and to Conal Elliott
-%%% <conal@MICROSOFT.com> and Marc van Dongen <dongen@cs.ucc.ie> for pointing
-%%% out a tricky bug.
-%%%
-%%% TODO ======================================================================
-%%%
-%%% B ~ bug; F ~ feature
-%%%
-%%% * B: Consider to use the following alternative definition for \<..\>:
-%%%
-%%%        \def\<{\bgroup\@hsSpaceToApp\endhs}
-%%%        \def\endhs#1\>{\(\mathit{#1}\)\egroup}
-%%%
-%%%      It completely avoids the problem that \mathit\bgroup..\egroup isn't
-%%%      guaranteed to work and seems more elegant, anyway.
-%%%
-%%% * F: Along the lines of the discussion with Martin Erwig add support for
-%%%      keywords etc (see the emails)
-%%%
-%%% * B: If we have as input 
-%%%
-%%%        \<map
-%%%        g\>
-%%%
-%%%      there won't be a `\hsap' inserted!!  (Can this be solved by using
-%%%      \obeylines in \<...\>?)
-%%%
-%%% * B: A \relax is needed after a & if it immediately followed by a \hsbody{}
-%%%   (See TeXbook, S.240)
-%%%
-%%% * F: Implement a \hstext{...} as \(\text{...}\).
-%%%
-%%% * F: Star-form of \hscom that uses "---" instead of "-\hskip0pt-"
-%%%
-%%% * We would like hswhere* etc that are like haskell* (\hsalign already
-%%%   supports this, ie, there is a \hsalign*).
-%%%
-%%% * Star-Versions of if, let etc that use a single line layout (maybe not
-%%%   with star, because of the above).
-%%%
-%%% * Support for enforcing and prohibiting breaks in `haskell' displays.
-%%%
-%%% * Comments in a let-in should be aligned in the same way for the bindings
-%%%   and the body.
-%%%
-%%% * It would be nice to have different styles (indentation after in of
-%%%   let-in or not) etc; either to be set with a package option or in the
-%%%   preamble (the latter probably makes more sense). 
-%%%
-%%% * Literate programming facility: Variant of the `haskell' env (maybe
-%%%   `hschunk', which is named and can be used in other chunks).  But maybe
-%%%   it is not necessary to provide a chunk-based reordering mechanism,
-%%%   because most of the Haskell stuff can be in any order anyway...
-%%%   Important is to provide a way to define visually pleasing layout
-%%%   together with the raw Haskell form for program output. (Maybe `haskell*' 
-%%%   as Haskell env that outputs its contents?)

-
-% NOTE: The sole purpose of the following is to work around what I believe is
-%       a bug in LaTeX.  If the first occurrence of \mathit in a document uses
-%       \bgroup and \egroup to enclose the argument (instead of { and }),
-%       \mathit does *not* apply to the argument.  (I guess, some font
-%       initialisation stuff is getting in the way of parsing the argument.)
-%
-%       The following forces a \mathit right after \begin{document}.
-%
-%       UPDATE: The LaTeX project people say that it isn't really a bug; more
-%               like a not supported form.  See alternative definition in the
-%               bug list above.

-%% Defining commands for use in the Haskell mode
-%% =============================================
-%%
-%% We use some of the low-level machinery defined in LaTeX's source file
-%% `ltdefns.dtx'.
-%%
-%% \hscommand is similar to \newcommand, but there is no *-version.
-%%
-%% We use our own definitions here to insert a strategic `\relax' (see below)
-%% and to obey spaces within the bodies of Haskell definitions.

-% All this trouble only to be able to add the `\relax' into the expansion

-% invoked after an alignment character & don't work properly (actually, the

-% \omit etc in \halign (TeXbook, p240), but I don't understand yet why it
