Please unblock package texlive-bin

[ Reason ]
Several fixes for shell escape exploits recently reported on the
private TeX Live security list have been fixed.
(No CVE or bug numbers are available)

[ Impact ]
TeX programs (like (la)tex, pdf(la)tex, lua(la)tex etc have a
"restricted" mode for calling external programs, where only a
specific set of vetted for programs are allowed. 

Without these fixes it will be rather easy to call arbitrary programs
from tex/luatex/etc even when those programs run in restricted mode
(which is the default setup).

Another fix that is in this patch is for xdvi which didn't quote '&'
before passing it to the shell to start a program, which again allowed
for arbitrary program execution.

[ Tests ]
All exploits have been tested before and after the fix. On request I
will send the exploit code.

[ Risks ]
One fix that has been done is that in restricted mode, luatex does not
allow putenv (change of environment variables) anymore, because this
would allow PATH changes, and thus circumvention of restricted mode
setting.

Some packages might use putenv (lua) on purpose and good way, which
might be broken when run in restricted mode, although we (that is
upstream TeX Live as well as the Debian team) are not aware of any.

[ Checklist ]
  [X] all changes are documented in the d/changelog
  [X] I reviewed all changes and I approve them
	I made them and backported them
  [X] attach debdiff against the package in testing
	I attach the three patches added to the patch
	queue in debian/patches. All other changes are
	just changelog entry and one patch renaming
	for consistency. All the code changes are attached.
