848835a3d8 mesa: added _mesa_clone_vertex/fragment_program()

a2ddb3d209 mesa: change _mesa_find_free_register() to find multiple free regs 
Before, _mesa_find_free_register() would scan the given shader to
find a free/unused register of the given type.  But subsequent calls
would return the same register again.  This caused a failure in the
_mesa_remove_output_reads() function which sometimes needs several
free temps.

Now use a new function which build a vector of 'used' flags and another
function which searches that vector for an unused register starting at
a position that's incremented for each call.

Fixes fd.o bug 26317.  Note that a regression test for this has been
added to the glean/glsl1 test.

bbd287103d mesa: prefix a bunch of #include lines with "main/". 
This is another step toward removing a whole bunch of -I flags from
the cc commands.  Still need to address driver code...

df43fb661b implement full reference counting for vertex/fragment programs 
Use _mesa_reference_vert/fragprog() wherever we assign program pointers.
Fixes a memory corruption bug found with glean/api2 test.

0c6723aee5 Add a size parameter to _mesa_add_unnamed_constant() and 
_mesa_add_named_constant() to indicate vector size (1, 2, 3 or 4).
Always 4 for now...

699a33ea77 Add new _mesa_lookup_parameter_constant() to search for a GLfloat4 constant 
in a parameter list.
Use it in _mesa_add_named_constant() and _mesa_add_unnamed_constant() to
avoid duplication of identical constants.

f49c0d0dfb Rename _mesa_IsProgram() to _mesa_IsProgramARB() to avoid collision with the 
OpenGL 2.0 function of the same name.

187f2cfb4a Add a new internal program parameter value STATE_TEXRECT_SCALE which 
provides 1/width and 1/height of the active texture, useful for
implementing ARB_texture_rectangle support on hardware which only
supports ARB_npot-style texturing.

5658810660 Export _mesa_print_alu_instruction() to allow drivers to roll their 
own debug code for programs with driver-private opcodes.

4d12a05e6c Added _mesa_lookup_program() and _mesa_lookup_bufferobj() functions to avoid 
a lot of casting elsewhere.

driver.

63d683091f No longer derive 'ati_fragment_shader' from 'program' class. Only the 
program->Id and program->RefCount fields were used and ATI fragment shaders
didn't have too much in common with ARB/NV vertex/fragment programs anyway.

de99760bf3 Move stuff common to vertex/fragment_program into the base class, including: 
Instructions, InputsRead, OutputsWritten, and Parameters.
Also, added debug functions: _mesa_print_instruction(),
_mesa_print_program_parameters() and revamp _mesa_print_program().
