* src/parse-gram.y: Clean up sorting of declarations.
Use types to simplify %printer declarations where possible.
Provide %printer for BRACKETED_ID and symbol.prec.

Provide %printer for BRACKETED_ID and symbol.prec.
* src/symtab.c: Whitespace change.
Except when memory reallocation is required, this change
eliminates the need to invoke yysyntax_error twice and thus to
repeat the collection of lookaheads. It also prepares for
future extensions that will make those repetitions more
expensive and that will require additional memory management in
yysyntax_error. Finally, it fixes an obscure bug already
exercised in the test suite.
* data/yacc.c (yysyntax_error): Add arguments for message
buffer variables stored in the parser. Instead of size, return
status similar to yyparse status but indicating success of
message creation. Other than the actual reallocation of the
message buffer, import and clean up memory management code
from...
(yyparse, yypush_parse): ... here.
* tests/regression.at (%error-verbose overflow): No longer an
expected failure.

yytable comments: zero indicates syntax error not default
action.
* data/glr.c (yyis_pact_ninf): Rename to...
(yypact_value_is_default): ... this.
(yyisDefaultedState): Update for rename.
(yyis_table_ninf): Rename to...

(yygetLRActions): Check for default value from yypact. It
appears that this check is always performed before this function
is invoked, and so adding the check here is probably redundant.
However, the code may evolve after this subtlety is forgotten.
Also, update for rename to yytable_value_is_error. Because that
macro now checks for zero, a different but equivalent branch of
the if-then-else here is evaluated.

yytable_value_is_error. The zero condition was mishandled
before.
