glr.cc, yacc.c: initialize yylloc properly
There are several issues to address here. One is that yylloc should
be initialized when possible. Another is that the push parser needs
to update yypushed_loc when the user modified it. And if the parser
starts by a reduction of an empty, it uses the first location on the
stack, which, therefore, must also be initialized to this initial
location.
This is getting complex, especially since because initializing a
global (impure interface) is different from initializing a local
variable. To simplify, the local yylloc is not initialized during its
definition.

yacc.c: initialize yylval and yylloc.
When generating a pure push parser, the initialization of yylval and
yylloc may not be visible to the compiler. With warnings enabled, GCC
4.3.6, 4.4.7, 4.5.4, and 4.6.3 report uninitialized uses of
yylval/yylloc. Using local pragmas to disable these warnings is not
supported before 4.6, and 4.6 does not support it properly. So
initialize yylval and yylloc at their definition. Reported by Peter
Simons. See
http://lists.gnu.org/archive/html/bison-patches/2012-10/msg00133.html

The "shadows a global declaration" warning in GCC 4.0 was a bit
annoying. It does not like that a type name be used in a prototype of
a function (not the implementation, just the declaration):
In file included from src/LR0.c:38:
src/reader.h:56: warning: declaration of 'named_ref' shadows a
global declaration
src/named-ref.h:35: warning: shadowed declaration is here
It does not like either when a global variable name is used in a
prototype. Flex 2.5.37 generates this prototype:
void gram_set_debug (int debug_flag );
* src/getargs.h, src/getargs.c (debug_flag): Rename as...
(debug): this.
Adjust dependencies.
* src/reader.h: Don't use "named_ref" as a formal argument name.
