more latex problems with references inside parsed-literal directive (``\DUrole``)

[jfbu]

The latex writer uses \DUrole with a comma separated first argument, but if this is found inside alltt environment, the comma is TeX active and this breaks latex compilation.

.. _mysection:

Section
-------

.. parsed-literal::

   public :ref:`mysection`  antidiag()

latex file contains

\begin{alltt}
public {\hyperref[index:mysection]{\sphinxcrossref{\DUrole{std,std-ref}{Section}}}}  antidiag()
\end{alltt}

and the problem comes from the comma inside \DUrole. Reported at #2026 (comment).

[jfbu]

Not only the comma in \DUrole{std,std-ref} but also the - is problematic. This is why I opted for \DUrole{\detokenize{std,std-ref}} approach by latex writer at #3208 .

e9c472c fixes this by moving \detokenize insertion to inside \DUrole LaTeX macro definition itself.

Analogous issue #3200 fixed at #3206 can't do the same because there would be many core LaTeX macros to patch: \hyperref, \ref, \pageref, nameref, \bibitem, \cite... whic is definitely to avoid. Hence #3206 inserts \detokenize explicitely in latex output.
