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.

Old languages (GLSL <= 4.20 and GLSL ES 1.00) require "invariant"
to be specified on both inputs and outputs, and match when linking.
New languages only allow outputs to be qualified as "invariant"
and remove the "invariant must match" restriction when linking
varyings (because no input can have that qualifier).
Commit 426a50e208 introduced the new
behavior for ES 3.00. It also removed the "must match" restriction
for ES 1.00 shaders, which I believe is incorrect. This patch adds
that back, as well as making 4.30+ follow the new rules.
Thanks to Qiankun Miao for noticing this discrepancy.

For geometry/compute inputs and tess control outputs, we create
an AST node to keep track of some things. However if we have
multiple layout sections, we don't ever link the node into the AST.
This is because we create the node on the rightmost layout declaration
and don't pass it back in so it gets linked at the end of the parsing
of the rightmost.

We reuse the existing offset field for holding the xfb_offset
expression but create a new flag as to avoid hitting the rules
for the offset qualifier for UBOs.
xfb_buffer qualifiers require extra processing when merging as
they can be applied to global out defaults. We just apply the
same rules as we do for the stream qualifier as the spec says:
"The *xfb_buffer* qualifier follows the same conventions,
behavior, defaults, and inheritance rules as the qualifier
stream, and the examples for stream apply here as well."
For xfb_stride we push everything into a global out field for
later processing as xfb_stride applies to the entire buffer.
We still need to have a separate field to store per variable
strides because they can still effect implicit offsets
e.g. when applied to block members with implicit offsets.

In a shader such as:
struct S { float f; }
float identity(float S) { return S; }
we would think that "S" in "return S" referred to a structure, even
though it's shadowed by the "float S" parameter in the inner struct.
This led to the parser's grammar seeing TYPE_IDENTIFIER and getting
confused.

The lexer/parser use a symbol table to classify identifiers as
variables, functions, or structure types.
For some reason, we neglected to add variables in simple declarations
such as
int x = 5;
but did add subsequent variables in multi-declarations:
int x = 5, y = 6; // y gets added, but not x, for some reason
Fixes four dEQP-GLES2.functional.shaders.scoping.valid subcases:
- local_int_variable_hides_struct_type_vertex
- local_int_variable_hides_struct_type_fragment

Previously interface blocks were giving the global default flags of
uniform blocks. This meant we could not check for invalid qualifiers
on interface blocks because they always contained invalid flags.
This changes parsing so that interface blocks now get an empty
set of layouts.
