mesa: Fix locking of GLsync objects.

GLsync objects had a race condition when used from multiple threads
(which is the main point of the extension, really); it could be
validated as a sync object at the beginning of the function, and then
deleted by another thread before use, causing crashes. Fix this by
changing all casts from GLsync to struct gl_sync_object to a new
function _mesa_get_and_ref_sync() that validates and increases
the refcount.

In a similar vein, validation itself uses _mesa_set_search(), which
requires synchronization -- it was called without a mutex held, causing
spurious error returns and other issues. Since _mesa_get_and_ref_sync()
now takes the shared context mutex, this problem is also resolved.

Fixes bug #92757, found while developing Nageru, my live video mixer
(due for release at FOSDEM 2016).

st/nine: Squash indexbuffer9 and vertexbuffer9

The indexbuffer9 codebase was lagging behind the one of vertexbuffer9.

Add buffer9 as common code base for indexbuffer9 and vertexbuffer9.

st/nine: Use ff vertex shader when position_t is used

When an application sets a vertex shader, we are supposed
to use it, and when no vertex shader are set, we are supposed
to revert to fixed function vertex shader.

It seems there is an exception: when the vertex declaration
has a position_t index, we should revert to fixed function
vertex shader.

Up to know we were checking if device->state.vs is set
to know whether to use programmable shader or not.

With this commit we determine whether we use programmable shader
or not when vertex shader/declaration are set, but
stateblocks do complicate things a bit.

However in practice when the flag is there, apps do use specular alpha
