adf0425d11 escape properly the file names in #line for printer/destructor 
Reported by Jannick.
http://lists.gnu.org/archive/html/bug-bison/2017-05/msg00001.html

"Amusingly" enough, we have the same problem with %defines when the
parser file name has backslashes or quotes: we generate #includes with
an incorrect C string.

* src/output.c (prepare_symbol_definitions): Escape properly the file
names before passing them to M4.
* data/bison.m4, data/lalr1.cc: Don't simply put the file name between
two quotes (that should have been strong enough a smell...), expect
the string to be properly quoted.
* tests/synclines.at: New tests to check this.

827bc59ca1 %union: fix the support for named %union 
Bison supports a union tag, for obscure reasons.  But it does a poor
job at it, especially since Bison 3.0.
Reported by Stephen Cameron and Tobias Frost.

It did not ensure that the name was not given several times.  An easy
way to do this is to make the %union tag be handled as a %define
variable, as they cannot be defined several times.

Since Bison 3.0, the synclines were wrongly placed, resulting in
invalid code.  Addressing this issue, because of the way the union tag
was stored (as a code muscle), would have been tedious.  Unless we
rather define the %union tag as a %percent variable, whose synclines
are easier to manipulate.

So replace the b4_union_name muscle by the api.value.union.name
%define variable, document, and check.

* data/bison.m4: Make sure that api.value.union.name has a keyword value.
* data/c++.m4: Make sure that api.value.union.name is not defined.
* data/c.m4 (b4_union_name): No longer use it, use api.value.union.name.
* doc/bison.texi (%define Summary): Document it.
* src/parse-gram.y (union_name): No longer define b4_uion_name, but
api.value.union.name.
* tests/input.at (Redefined %union name): New.
* tests/synclines.at (%union name syncline): New.
* tests/types.at: Check named %unions.

lines change often.  Fuse them into a single, shorter, line:

0505df0cba errors: factor b4_error @directives 
Instead of @complain, @warn, and @fatal, use a unique @complain
directive. This directive's first argument is "complain", "warn", etc.

* data/bison.m4 (m4_error): Here.
* src/scan-skel.l (at_directive_perform): Adjust.
(flag): Replace the switch by safer and more explicit if branches.

e3990e3c99 output: use the token list to define the yytokentype 
There are currently two systems used to pass information about tokens to

printers and destructors, variants etc.  Move to using only the latter.
