Subject: ARB prog parser: Fix epic memory leak in lexer / parser interface

Anything that matched IDENTIFIER was strdup'ed and returned to the
parser.  However, almost every case of IDENTIFIER in the parser just
dropped the returned string on the floor.  Every swizzle string, every
option string, every use of a variable, etc. leaked memory.

Create a temporary buffer in the parser state (string_dumpster and
dumpster_size).  Return strings from the lexer to the parser in the
buffer.  Grow the buffer as needed.  When the parser needs to keep a
string (i.e., delcaring a new variable), let it make a copy then.

The only leak that valgrind now detects is /occasionally/ the copy of
the program string in gl_program::String is leaked.  I'm not seeing
how. :(

From 731810f8546174e45c717b0a9aa289a26593dfa0 Mon Sep 17 00:00:00 2001
From: Ian Romanick <ian.d.romanick@intel.com>
Date: Mon, 2 Nov 2009 12:44:14 -0800
Subject: ARB prog parser: Fix a couple issues with previous merge from
 mesa_7_6_branch

Since the addition of support for Nvidia condition codes, the lexer internally
uses handle_ident to select between returning IDENTIFIER and USED_IDENTIFIER.
Also, use return_string instead of strdup.

Fixes bug #24809.

From 1c7337d46eab0cfd36ebc0ad22c5a66ec9b91d39 Mon Sep 17 00:00:00 2001
From: Ian Romanick <ian.d.romanick@intel.com>
Date: Wed, 4 Nov 2009 12:03:44 -0800
Subject: Revert "ARB prog parser: Fix epic memory leak in lexer / parser
 interface"

This reverts commit 93dae6761bc90bbd43b450d2673620ec189b2c7a.

This change was completely broken when the parser uses multiple
strings in a single production.  It would be nice if bug fixes could
initially land somewhere other than the stable branch.
