Joel E. Denny 2728ac7ecd portability: <' and >' are not always defined on addresses.
Specifically, don't sort objects by their memory addresses when
they're not allocated in the same array or other object.  Though
I haven't found a test case where that fails on my platform, C
says the behavior is undefined.
* src/AnnotationList.c (AnnotationList__insertInto): Remove
FIXME.  Use new id field of InadequacyList nodes rather than
their memory addresses when sorting.
(AnnotationList__compute_from_inadequacies): Add
inadequacy_list_node_count argument to pass to
InadequacyList__new_conflict.
* src/AnnotationList.h
(AnnotationList__compute_from_inadequacies): Update prototype
and documentation for new argument.
* src/InadequacyList.c (InadequacyList__new_conflict): Add
node_count argument and use it to assign a unique ID.
* src/InadequacyList.h (InadequacyListNodeCount): New typedef.
(InadequacyList): Add id field.
(InadequacyList__new_conflict): Update prototype and
documentation for new argument.
* src/ielr.c (ielr_compute_annotation_lists): Update
AnnotationList__compute_from_inadequacies invocation.

Joel E. Denny abcc7c03cc Fix handling of yychar manipulation in user semantic actions.
The problem was that yacc.c didn't always update the yychar
translation afterwards.  However, other skeletons appear to be
fine.  glr.c appears to already translate yychar before every
use.  lalr1.cc does not define yychar and does not document its
replacement, yyla, for users.  It does provide yyclearin, but
that does not manipulate yyla and thus requires no translation
update.  In lalr1.java, yychar is out of scope during semantic
actions.
* NEWS (2.5): Document.
* data/yacc.c (YYBACKUP): Don't bother translating yychar into
yytoken here.
(yyparse, yypush_parse): Instead, translate before every use of
yytoken, and add comments explaining this approach.
* tests/actions.at (Destroying lookahead assigned by semantic
action): New test group checking that translation happens before
lookahead destructor calls at parser return.  Previously,
incorrect destructors were called.
* tests/conflicts.at (%error-verbose and consistent
errors): New test group checking that translation happens at
syntax error detection before the associated verbose error
message and the associated lookahead destructor calls.  While
the destructor call is fixed by this patch, the verbose error
message is currently incorrect due to another bug (see
comments in test group), so this is an expected failure for now.

Joel E. Denny 69a2ab11cf yysyntax_error: avoid duplicate lookahead collection.
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
