with glr.cc.

Some other wording changes.
This is not just nicer, it is also much safer, since we were
using sprintf...

Adjust dependencies.

src/scan-skel.l:145: multiple <<EOF>> rules for start condition SC_AT_DIRECTIVE_ARGS
src/scan-skel.l:145: multiple <<EOF>> rules for start condition SC_AT_DIRECTIVE_SKIP_WS
This is warning, and it seems there are no means to make it an error.
* src/scan-skel.l: Restore the start-condition INITIAL for an <<EOF>>
clause.
* cfg.mk: Nuke the following warnings which are confused by our
text reports (that state that the error token is number 256).

scan-code.l is already passing argument to b4_dollar_dollar for the
initial acton, but its definition (of b4_dollar_dollar) does not use
this argument.
Generalize this definition, and use it for the %initial-action too.
* data/c.m4 (b4_dollar_dollar_, b4_dollar_pushdef, b4_dollar_popdef):
Instead of expecting a pointer, require a value, and use ".".
Since they are now generic enough, move to...
* data/c-like.m4: this new file.
* data/c.m4, data/java.m4: Load it.
* data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Use
b4_dollar_pushdef for the %initial-action.
* tests/actions.at: Check that.
* data/Makefile.am: Adjust.
* NEWS, doc/bison.texi: Document.
Currently "%printer {...} a b c d e f" translates the {...} six times.
Not only is this bad for time and space, it also issues six times the
same warnings.
* src/symlist.h, src/symlist.c (symbol_list_destructor_set)
(symbol_list_printer_set): Take the action as code_props instead of
const char *.
* src/parse-gram.y: Translate these actions here.
* src/scan-code.h: Comment change.
* tests/input.at: Check that warnings are issued only once.
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,
use it.
It sure is less efficient, but the cost is negligible.
This allows to factor rules that are alike.
And to factor some start-condition clauses.
* tests/input.at (Stray $ or @): New.
* NEWS: Document it.
* src/scan-code.l, src/scan-skel.l: Use a more traditional indentation
style for start-conditions.
Prefer "continue" to a comment, for empty actions.
Strip useless {}.
Remove useless start-condition clauses.
* src/scan-code.l (SC_SYMBOL_ACTION): Accept $<tag>$, not just $$.
* data/c.m4 (b4_dollar_dollar_): New.
(b4_symbol_actions): Let b4_dollar_dollar use b4_dollar_dollar_.
* NEWS, doc/bison.texi: Document it.
* tests/actions.at: Check this for C and C++.
* src/output.c (quoted_output): Split into...
(quoted_output, string_output): these.
Use the former when outputting a type_name.
* tests/input.at: Check this case.
* src/symtab.h: Comment changes.
With GCC 4.8, the tests on synclines are skipped. Transform
input.y:1:2: error: #error "1"
#error "1"
^
into
input.y:1: #error "1"
* tests/synclines.at (AT_SYNCLINES_COMPILE): Do it, using Perl instead of
sed.
* src/scan-code.l: Use obstack_quote when passing type_name to m4.
* tests/input.at (Code injection): New.
* NEWS: Document it.
Thanks to Paul Eggert for the wording.
* src/system.h (obstack_quote): New.
* 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 "".
* src/muscle-tab.c (MUSCLE_COMMON_DECODE, muscle_string_decode)
(muscle_location_decode): Not related to muscles, rename as...
(COMMON_DECODE, string_decode, location_decode): these.
* src/muscle-tab.h (MUSCLE_OBSTACK_SGROW): This is not related to
muscles, so move to, and rename as...
* src/system.h (obstack_escape): this.
Adjust dependencies.
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...
(Index of Terms): this.
* configure.ac: In the AC_SUBST call on 'VALGRIND_PREBISON'. Without
this change, when running ./configure, I see:
...
checking for valgrind... valgrind
./configure: line 35221: -q: command not found
checking for Java compiler... gcj -C -fsource=1.3 -ftarget=1.4
