The EXT_shader_framebuffer_fetch extension defines alternative
language for GLES2 shaders where user-defined fragment outputs are not
allowed. Instead of using inout user-defined fragment outputs the
shader is expected to read from the gl_LastFragData built-in array.
In addition this allows using the same language on desktop GLSL
versions prior to 4.2 that support the deprecated gl_FragData built-in
in preparation for the MESA_shader_framebuffer_fetch desktop GL
extension.
Both legacy and user-defined inout outputs have a common
representation at the GLSL IR level, so it shouldn't make any
difference for optimization passes and back-ends whether the
application is using gl_LastFragData or user-defined outputs, all
they'll see is a variable dereference of a fragment output at a
certain interface location with the fb_fetch_output bit set to one.
v2: Don't define the built-in variable on GLSL versions for which
gl_FragData exists but is deprecated. (Ken)

According to the EXT_shader_framebuffer_fetch extension the inout
qualifier can be used on ESSL 3.0+ shaders to declare a special kind
of fragment output that gets implicitly initialized with the previous
framebuffer contents at the current fragment coordinates. In addition
we allow using the same language to define FB fetch outputs in GLSL
1.3+ shaders in preparation for the desktop MESA_shader_framebuffer_fetch
extensions.

The GLSL IR representation of framebuffer fetch amounts to a single
bit in the ir_variable object applicable to fragment shader outputs.
The flag indicates that the variable will be implicitly initialized to
the previous contents of the render buffer at the same fragment
coordinates and sample index.

Both MESA_shader_framebuffer_fetch_non_coherent and the non-coherent
variant of KHR_blend_equation_advanced will use this driver hook to

Before this commit, GetProgramInterfaceiv for pname ACTIVE_RESOURCES

returning the count of resources on the shader program using that
interface, instead of the num of uniform resources. This would get a

uniforms.
Note that this means that in order to get a proper value, the shader
needs to be linked, something that is not explicitly mentioned on
ARB_program_interface_query spec, but comes from the general
definition of active uniform. If the program is not linked we
return 0.

Several fixes have been added as part of this as listed below:
1) Fix the mask and add disassembler handling for STATE_DS, STATE_HS
as the mask returned wrong values of the fields.
2) Fix the GEN_TYPE_ADDRESS/GEN_TYPE_OFFSET decoding - the address/
offset were handled the same way as the other fields and that gives
the wrong values for the address/offset.
3) Decode nested/recurssive structures - Many packets contain nested
structures, ex: 3DSATE_SO_BUFFER, STATE_BASE_ADDRESS, etc contain MOC
structures. Previously, the aubinator printed 1 if there was a MOC
structure. Now we decode the entire structure and print out its fields.
4) Print out the DWord address along with its hex value - For a better
clarity of information, it is helpful to print both the address and
hex value of the DWord along with the DWord count. Since the DWord0
contains the instruction code and the instruction length, it is
unnecessary to print the decoded values for DWord0. This information
is already available from the DWord hex value.
5) Decode the <group> and the corresponding fields in the group- The
<group> tag can have fields of several types including structures. A
group can contain one or more number of fields and this has be correctly
decoded. Previously, aubinator did not decode the groups or the
fields/structures inside them. Now we decode the <group> in the
instructions and structures where the fields in it repeat for any number
of times specified.
