* src/named-ref.c: Add a pointer check (named_ref_free).
* src/scan-code.l: New function (variant_table_free). Called in
code_scanner_free.
* src/symlist.c: Call to named_ref_free (symbol_list_free).
* NEWS (2.5): Document.
* src/scan-gram.l (INITIAL): Remove comment that we don't check
the length.
(SC_ESCAPED_CHARACTER): Warn if length is wrong.
* tests/input.at (Bad character literals): New test group.

* tests/existing.at (_AT_TEST_EXISTING_GRAMMAR): Do not
complicate the code by distinguishing between a missing value
and an empty string value for an optional argument. This fix is
allowed by the similar fix in AT_TEST_TABLES_AND_PARSE below.
* tests/local.at (_AT_TEST_TABLES_AND_PARSE): Merge into...
(AT_TEST_TABLES_AND_PARSE): ... this now that the special
arguments are not needed because of the following changes.
Fix stale comments.
Bison developers should use GNU M4 and should not use
POSIXLY_CORRECT when building the test suite, so do not
complicate the code by avoiding $10 and above.
Do not quote an empty string value for an optional argument, and
do not distinguish between a missing value and an empty string
value.

* src/named-ref.h: Add comments.
* src/parse-gram.y: Readability and style changes.
* src/reader.c: Factoring: assign_named_ref function.
* src/scan-code.l: Factoring and style changes. Rename
parse_named_ref to parse_ref. Use "c-ctype.h" from gnulib.
Use "unsigned" type for variant index. Improve readablity.

Depend on it to create the sources of calc++ so that concurrent
builds don't launch several "extexi" in parallel.
Not only this is inefficient, this also builds incorrect sources
with several extractions mixed together.

* data/bison.m4: Move code related to specific variables after the
definition of the variable-maintaining macros so that we don't
"invoke" b4_percent_define_check_values before it is defined.
Implement, document, and test the replacement of %error-verbose
by %define parse.error "verbose".
* data/bison.m4 (b4_error_verbose_if): Reimplement to track the
values of the parse.error variable.
Make "simple" its default value.
Check the valid values.
* src/parse-gram.y: Use %define parse.error.
(PERCENT_ERROR_VERBOSE): New token.
Support it.
* src/scan-gram.l: Support %error-verbose.
* doc/bison.texinfo (Decl Summary): Replace the documentation of
%define error-verbose by that of %define parse.error.
* NEWS: Document it.
* tests/actions.at, tests/calc.at: Use parse.error instead of
%error-verbose.

* data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
New.
(b4_percent_define_use): New.
Use it where applicable.
* data/c++.m4: Replace uses of the variable "namespace" by
"api.namespace".
Default the latter to the former.
* doc/bison.texinfo (Decl Summary): Document "namespace" as
obsolete.
Document api.namespace.
Use @samp to document %define uses, keep @code for identifiers.
* NEWS: Likewise.
* tests/c++.at, tests/input.at: Test api.namespace instead of
namespace. (The tests passed with namespace.)
Some consistency checks on symbols are performed after all the
symbols were read, by an iteration over the symbol table. This
traversal is nondeterministic, which can be a problem for test
cases.
Avoid this.
Addresses another form of nondeterminism reported by Joel E. Denny.

* tests/input.at (Numbered tokens): Split the hexadecimal/decimal
test in two.
Use different file names for the three tests to make the
maintenance easier.
