Merge remote-tracking branch 'origin/maint'
* origin/maint:
maint: formatting changes.
tests: support api.prefix.
tests: pacify font-lock-mode.
tests: remove test covered elsewhere.
tests: factor the declaration/definition of yyerror and yylex.
regen.
tests: portability issues.
tests: call the parser from another compilation unit.
glr.c, yacc.c: declare yydebug in the header.
skeletons: use header guards.
tests: improve AT_FULL_COMPILE.
tests: reorder.
tests: strengthen the test on generated headers inclusion
yacc.c: instead of duplicating y.tab.h inside y.tac.c, include it.
yacc.c: factor.

+* Noteworthy changes in release ?.? (????-??-??) [?]
+
+** Future changes:
+
+ The next major release will drop support for generating parsers in K&R C,
+ and remove the definition of yystype (removal announced since Bison
+ 1.875).
+
+** The generated header is included (yacc.c)
+
+ Instead of duplicating the content of the generated header (definition of
+ YYSTYPE, yyltype etc.), the generated parser now includes it, as was
+ already the case for GLR or C++ parsers.
+
+** Headers (yacc.c, glr.c, glr.cc)
+
+*** Guards
+
+ The generated headers are now guarded, as is already the case for C++
+ parsers (lalr1.cc). For intance, with --defines=foo.h:
+
+ #ifndef YY_FOO_H
+ # define YY_FOO_H
+ ...
+ #endif /* !YY_FOO_H */
+
+*** New declarations
+
+ The generated header now declares yydebug and yyparse. Both honor
+ --name-prefix=bar_, and yield
+
+ int bar_parse (void);
+
+ rather than
+
+ #define yyparse bar_parse
+ int yyparse (void);
+
+ in order to facilitate the inclusion of several parser headers inside a
+ single compilation unit.
