program_interface_query: add tests for getprogramresourceiv

Tested on NVIDIA's proprietary driver version 346.35.

v2:
- test GL_ATOMIC_COUNTER_BUFFER (hackish since indexes are hardcoded)
- cosmetic changes in a switch
- fix a typo: inconsitent -> inconsistent
- require GL_ARB_separate_shader_objects
- compile some programs as separable

+ * \file getprogramresourceiv.c
+ *
+ * Tests the values returned by GetProgramResourceiv on multiple pipelines.
+ * Also checks some error cases.
+ *
+ * From the GL_ARB_program_interface_query spec:
+ *  "The command
+ *
+ *  void GetProgramResourceiv(uint program, enum programInterface,
+ *                            uint index, sizei propCount,
+ *                            const enum *props, sizei bufSize,
+ *                            sizei *length, int *params);
+ *
+ *  returns values for multiple properties of a single active resource with an
+ *  index of <index> in the interface <programInterface> of program object
+ *  <program>.  For each resource, values for <propCount> properties specified
+ *  by the array <props> are returned.  The error INVALID_VALUE is generated
+ *  if <propCount> is zero.  The error INVALID_ENUM is generated if any value
+ *  in <props> is not one of the properties described immediately below.  The
+ *  error INVALID_OPERATION is generated if any value in <props> is not
+ *  allowed for <programInterface>.  The set of allowed <programInterface>
+ *  values for each property can be found in Table X.1.
+
+ *  The values associated with the properties of the active resource are
+ *  written to consecutive entries in <params>, in increasing order according
+ *  to position in <props>.  If no error is generated, only the first
+ *  <bufSize> integer values will be written to <params>; any extra values
+ *  will not be returned.  If <length> is not NULL, the actual number of
+ *  integer values written to <params> will be written to <length>.

+ *
+ *  For the property NAME_LENGTH, a single integer identifying the length of
+ *  the name string associated with an active variable, interface block, or
+ *  subroutine is written to <params>.  The name length includes a terminating
+ *  null character.
+ *
+ *  For the property TYPE, a single integer identifying the type of an active
+ *  variable is written to <params>.  The integer returned is one of the
+ *  values found in table 2.16.
+ *
+ *  For the property ARRAY_SIZE, a single integer identifying the number of
+ *  active array elements of an active variable is written to <params>. The
+ *  array size returned is in units of the type associated with the property
+ *  TYPE. For active variables not corresponding to an array of basic types,
+ *  the value one is written to <params>. If the variable is a shader
+ *  storage block member in an array with no declared size, the value zero
+ *  is written to <params>.
+ *
+ *  For the property BLOCK_INDEX, a single integer identifying the index of
+ *  the active interface block containing an active variable is written to
+ *  <params>.  If the variable is not the member of an interface block, the
+ *  value -1 is written to <params>.
+ *
+ *  For the property OFFSET, a single integer identifying the offset of an
+ *  active variable is written to <params>.  For active variables backed by a
+ *  buffer object, the value written is the offset, in basic machine units,
+ *  relative to the base of buffer range holding the values of the variable.
+ *  For active variables not backed by a buffer object, an offset of -1 is
+ *  written to <params>.
+ *
+ *  For the property ARRAY_STRIDE, a single integer identifying the stride
+ *  between array elements in an active variable is written to <params>.  For
+ *  active variables declared as an array of basic types, the value written is
+ *  the difference, in basic machine units, between the offsets of consecutive
+ *  elements in an array.  For active variables not declared as an array of
+ *  basic types, zero is written to <params>.  For active variables not backed
+ *  by a buffer object, -1 is written to <params>, regardless of the variable
+ *  type.
+ *
+ *  For the property MATRIX_STRIDE, a single integer identifying the stride
+ *  between columns of a column-major matrix or rows of a row-major matrix is
+ *  written to <params>.  For active variables declared a single matrix or
+ *  array of matrices, the value written is the difference, in basic machine
+ *  units, between the offsets of consecutive columns or rows in each matrix.
+ *  For active variables not declared as a matrix or array of matrices, zero
+ *  is written to <params>.  For active variables not backed by a buffer
+ *  object, -1 is written to <params>, regardless of the variable type.
+ *
+ *  For the property IS_ROW_MAJOR, a single integer identifying whether an
+ *  active variable is a row-major matrix is written to <params>.  For active
+ *  variables backed by a buffer object, declared as a single matrix or array
+ *  of matrices, and stored in row-major order, one is written to <params>.
+ *  For all other active variables, zero is written to <params>.
+ *
+ *  For the property ATOMIC_COUNTER_BUFFER_INDEX, a single integer identifying
+ *  the index of the active atomic counter buffer containing an active
+ *  variable is written to <params>.  If the variable is not an atomic counter
+ *  uniform, the value -1 is written to <params>.
+ *
+ *  For the property of BUFFER_BINDING, to index of the buffer binding point
+ *  associated with the active uniform block, shader storage block, or atomic
+ *  counter buffer is written to <params>.
+ *
+ *  For the property of BUFFER_DATA_SIZE, then the implementation-dependent
+ *  minimum total buffer object size, in basic machine units, required to hold
+ *  all active variables associated with an active uniform block, shader
+ *  storage block, or atomic counter buffer is written to <params>.  If the
+ *  final member of an active shader storage block is array with no declared
+ *  size, the minimum buffer size is computed assuming the array was declared
+ *  as an array with one element.
+ *
+ *  For the property of NUM_ACTIVE_VARIABLES, the number of active variables
+ *  associated with an active uniform block, shader storage block, or atomic
+ *  counter buffer is written to <params>.
+ *
+ *  For the property of ACTIVE_VARIABLES, an array of active variable indices
+ *  associated with an active uniform block, shader storage block, or atomic
+ *  counter buffer is written to <params>.  The number of values written to
+ *  <params> for an active resource is given by the value of the property
+ *  NUM_ACTIVE_VARIABLES for the resource.
+ *
+ *  For the properties REFERENCED_BY_VERTEX_SHADER,
+ *  REFERENCED_BY_TESS_CONTROL_SHADER, REFERENCED_BY_TESS_EVALUATION_SHADER,
+ *  REFERENCED_BY_GEOMETRY_SHADER, REFERENCED_BY_FRAGMENT_SHADER, and
+ *  REFERENCED_BY_COMPUTE_SHADER, a single integer is written to <params>,
+ *  identifying whether the active resource is referenced by the vertex,
+ *  tessellation control, tessellation evaluation, geometry, or fragment
+ *  shaders, respectively, in the program object.  The value one is written to
+ *  <params> if an active variable is referenced by the corresponding shader,
+ *  or if an active uniform block, shader storage block, or atomic counter
+ *  buffer contains at least one variable referenced by the corresponding
+ *  shader.  Otherwise, the value zero is written to <params>.
+ *
+ *  For the property TOP_LEVEL_ARRAY_SIZE, a single integer identifying the
+ *  number of active array elements of the top-level shader storage block
+ *  member containing to the active variable is written to <params>.  If the
+ *  top-level block member is not declared as an array, the value one is
+ *  written to <params>.  If the top-level block member is an array with no
+ *  declared size, the value zero is written to <params>.
+ *
+ *  For the property TOP_LEVEL_ARRAY_STRIDE, a single integer identifying the
+ *  stride between array elements of the top-level shader storage block member
+ *  containing the active variable is written to <params>.  For top-level
+ *  block members declared as arrays, the value written is the difference, in
+ *  basic machine units, between the offsets of the active variable for
+ *  consecutive elements in the top-level array.  For top-level block members
+ *  not declared as an array, zero is written to <params>.
+ *
+ *  For the property LOCATION, a single integer identifying the assigned
+ *  location for an active uniform, input, output, or subroutine uniform
+ *  variable is written to <params>.  For input, output, or uniform variables
+ *  with locations specified by a layout qualifier, the specified location is
+ *  used.  For vertex shader input or fragment shader output variables without
+ *  a layout qualifier, the location assigned when a program is linked is
+ *  written to <params>.  For all other input and output variables, the value
+ *  -1 is written to <params>.  For uniforms in uniform blocks, the value -1
+ *  is written to <params>.
+ *
+ *  For the property LOCATION_INDEX, a single integer identifying the fragment
+ *  color index of an active fragment shader output variable is written to
+ *  <params>.  If the active variable is an output for a non-fragment shader,
+ *  the value -1 will be written to <params>.
+ *
+ *  For the property IS_PER_PATCH, a single integer identifying whether the
+ *  input or output is a per-patch attribute.  If the active variable is a
+ *  per-patch attribute (declared with the "patch" qualifier), the value one
+ *  is written to <params>; otherwise, the value zero is written to <params>."
