If libxlu_cfg_y.y encountered a config file error, the code generated
by bison would sometimes _both_ run the %destructor _and_ call
xlu__cfg_set_store for the same XLU_ConfigSetting* semantic value.
The result would be a double free.
This appears to be because of the use of a mid-rule action. There is
some discussion of the problems with destructors and mid-rule action
error handling in "(bison)Mid-Rule Actions". This area is complex and
best avoided.
So fix the bug by abolishing the use of a mid-rule action, which was
in any case not necessary here.
Also while we are there rename the nonterminal rule "setting" to
"assignment", to avoid confusion with the token type "setting", which
had an identically name in a different namespace. This was especially
confusing because the nonterminal "setting" did not have "setting" as
the type of its semantic value! (In fact the nonterminal, now called
"assignment", does not have a value so it does not have a value type.)

This updates libxlu_cfg_y.[ch] to code generated by bison from
Debian squeeze (1:2.4.1.dfsg-3 i386).
There should be no functional change since there is no change to the
source file, but we will inherit bugfixes and behavioural changes from
the new version of bison. So this is more a matter of hope than
knowledge.

Several places which were previsously indented using hard tabs are now
incorrectly indented. Fix them up.

Copyright notices in libxlu_cfg_[ly].[ly] end up in the .[ch] files,
copied there by flex and bison. Regenerate those files (flex 2.5.35
and bison 2.3, from Debian lenny i386).
No manual edits in this patch.
