scan-code.l is already passing argument to b4_dollar_dollar for the

Generalize this definition, and use it for the %initial-action too.

Akim Demaille 263137264f factor the handling of m4 escaping
The conversion from @ to @@ and so forth is coded is too many
different places.  Factor, a bit.

* src/scan-code.l: Instead of duplicating the logic of obstack_escape,

It sure is less efficient, but the cost is negligible.
This allows to factor rules that are alike.

* src/muscle-tab.c: Use it instead of obstack_escape where applicable.
* src/scan-code.l: Since obstack_quote supports NULL, leave type_name
as NULL instead of defaulting to "".

Akim Demaille f9b8635172 doc: avoid problems with case insensitive file systems
makeinfo --html generates index.html, and the node "Index" will result
in Index.html.  On case insensitive file systems, such as on Mac OS X
by default, this results in a single, invalid, file (Texinfo 4.13).
See http://lists.gnu.org/archive/html/bug-texinfo/2012-07/msg00032.html

* doc/bison.texi (Index): Rename as...

Akim Demaille 9534d2be80 simplify the handling of <> and <*>'s code_props.
Currently they are treated in separated variables, contrary to other
<TYPE> code_props.  This duplicates code (and messages for translators)
uselessly, as demonstrated by the fact that thanks to this patch, now
useless <*> and <> code_props are reported like the others.

* src/parse-gram.y (generic_symlist_item): Treat "<*>" and "<>" as regular
type tags.
* src/symlist.h, src/symlist.c (symbol_list_default_tagged_new)
(symbol_list_default_tagless_new,SYMLIST_DEFAULT_TAGGED)

(default_tagless_code_props, default_tagged_code_props_set)

(symbol_code_props_get): Default to <*> or <>'s code_props.

* tests/actions.at: Complete expected errors: there are new warnings.
* tests/input.at: Likewise.
(Useless printers or destructors): Extend.

Akim Demaille 70946cff5e allow modification on retrieved code_props.
The logic to compute the %printer or %destructor to used (i.e., a
code_props) is implemented twice: one, of course, in
symbol_code_props_get, and another time in symbol_check_defined to
record the fact that a code_props is used (so that we can reported
unused ones).  Let the former use the latter.

I would probably use "mutable" in C++ and keep these guys const,
but this is C.  And casting away constness triggers warnings.

* src/scan-code.h, src/scan-code.l (code_props_none): Is not const.
* src/symtab.h, src/symtab.c (symbol_code_props_get): The symbol
is not const.
(symbol_check_defined): Use it.

Akim Demaille afa4ec917b maint: fix bison's own header guards.
Because I'm using a VPATH build with an absolute srcdir, I have
GRAM__USERS_AKIM_SRC_GNU_BISON_SRC_PARSE_GRAM_H.  Before, I was using
a relative srcdir, and had GRAM_______SRC_PARSE_GRAM_H (coming from
../../).  Let it be GRAM_SRC_PARSE_GRAM_H.

* tests/bison.in: Do not depend on the value of $top_srcdir for
Bison itself.
If we were to use relative paths from .c to .y, we would not have
this problem.
