Subject: [PATCH] mesa: Provide gl_vertex_format accessors.
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Provide the same set of VAO and current value gl_vertex_format
accessor functions like we have for the gl_array_attributes.
For most purpose the vertex format is what we need.

v2: Style fixes.
