There was only a single user which was using strlen(buf).
As this function is not user facing (i.e. we don't need to feed back
original length via a callback), we can simplify things.

This patch replaces the old interger constant qualifiers with either
the new ast_layout_expression type if the qualifier requires merging
or ast_expression if the qualifier can't have mulitple declarations
or if all but the newest qualifier is simply ignored.
We also update the process_qualifier_constant() helper to be
similar to the one in the ast_layout_expression class, but in
this case it will be used to process the ast_expression qualifiers.
Global shader layout qualifier validation is moved out of the parser
in this change as we now need to evaluate any constant expression
before doing the validation.

This is the guts of the GLSL parser and AST support for
shader subroutines.
The code creates a subroutine type in the parser, and
uses that there to validate the identifiers. The parser
also distinguishes between subroutine types/function prototypes
/uniforms and subroutine defintions for functions.
Then in the AST conversion it recreates the types, and
stores the subroutine definition info or subroutine info
into the ir_function along with a side lookup table in
the parser state. It also converts subroutine calls into
the enhanced ir_call.
v2: move to handling method calls in
function handling not in field selection.
v3: merge Chris's previous parser patches in here, to
make it clearer what's changed in one place.

Previously, the ctx->Const.ForceGLSLVersion setting only worked if
the shader lacked a #version directive. Now, the ForceGLSLVersion
setting will override the #version directive too.
This change should be safe since it should be rare to have an app
that has a mix of shader versions and we only wanted to override
the #version for shaders which lacked the #version directive.
