There are two distinctly different uses of this struct. The first
is to store GL shader objects. The second is to store information
about a shader stage thats been linked.
The two uses actually share few fields and there is clearly confusion
about their use. For example the linked shaders map one to one with
a program so can simply be destroyed along with the program. However
previously we were calling reference counting on the linked shaders.
We were also creating linked shaders with a name even though it
is always 0 and called the driver version of the _mesa_new_shader()
function unnecessarily for GL shader objects.

Since this extension allows more than one varying to share a single
location we can't just count the number of slots a varying takes and
add it to the total.
Instead we now reuse the reserved varyings bitfield to determine how
many slots are reserved for explicit locations instead.

This is prep work for int64 support.

From the ARB_enhanced_layous spec:
"It is a compile-time or link-time error to have any *xfb_offset*
that overflows *xfb_stride*, whether stated on declarations before
or after the *xfb_stride*, or in different compilation units.
...
When no *xfb_stride* is specified for a buffer, the stride of a
buffer will be the smallest needed to hold the variable placed at
the highest offset, including any required padding."

This adds the initial infrastructure for enabling transform feedback
mode via in shader qualifiers and adds initial buffer support.

We also apply any array/struct offsets.

This function checks for any xfb_* qualifiers which will enable
transform feedback mode and cause any API defined xfb varyings
to be ignored.
It also counts the number of varyings that have a xfb_offset
qualifier and finally it calls the create_xfb_varying_names()
helper to generate the names of varyings to be caputured.
