Description: LuaTeX fixes for obscure ways to work around some security features.

On this occasion I've taken the three commits in the mirror which were
relevant to this, and omitted the many other fixes, some of which are
only parts of an svn commit with other changes for texmf-dist (not in the
git mirror) and other fixes for minor issues in japanese variants, some
of which are very large commits. I have therefore also ignored the
change to fix the uuptex test.

+- A breaking backward compatibility change: by default the socket 
+  library is not enabled . 
+  The new option --socket enable the socket library as 
+  before, as also --shell-escape (without --shell-restricted);
+  --nosocket, --no-socket , --safer disabled the library, and 
+  they have the priority in case of conflicting options.
+  The mime library is always available; socket.sleep
+  and socket.gettime are duplicated as os.socketsleep
+  and os.socketgettime, both always available.
+  The new os.kpsepopen replace io.popopen in kpse mode
+  (i.e. when kpse_init is not zero) as it was before
+  but the permission now cannot be changed anymore with 
+  kpse.check_permission . 
+  The function os.kpsepopen follows the same restrictions
+  as io.popen .
+  Thanks to Max Chernoff for debugging.
