The glsl2 merge has introduced a regression in the "Domino" demo from Humus, the pieces no longer fall over but remain standing up.
All shaders report compile status ok.

Revert "mesa: Don't add 1 to GL_ACTIVE_UNIFORM_MAX_LENGTH."
This reverts commit 001a7bfdfc8b3c8930d5ced21982dbdfb8cd35b3. I
hadn't found the section of the spec clarifying that the old behavior
was right. Reverting fixes the new version of the testcase, and the
Humus demos that could no longer find their uniforms.
