Now we convert the split pieces of GL_LINE_LOOP prims into GL_LINE_STRIP
primitives so that drivers don't have to worry about the special begin/end
flags.  The only time a driver will get a GL_LINE_LOOP prim is when the
whole thing fits in one vertex buffer.

Mostly fixes bug 81174, but not completely.  There's another bug somewhere
in the src/gallium/auxiliary/draw/ code.  If the piglit lineloop test is
run with -count 4096, rendering is correct, but with -count 4097 there are
stray lines.  4096 is a magic number in the draw code (search for "4096").

Also note that this does not fix long line loops in display lists.  The
next patch fixes that.

v2: fix incorrect -1 in vbo_compute_max_verts(), per Charmaine.  Remove
incorrect assertion which was added in vbo_copy_vertices().

vbo: reduce number of vertex buffer mappings for vertex attributes

Whenever we got a glColor, glNormal, glTexCoord, etc. call outside a
glBegin/End pair, we'd immediately map a vertex buffer to begin
accumulating vertex data.  In some cases, such as with display lists,
this led to excessive vertex buffer mapping.  For example, if we have
a display list such as:

glNewList(42, GL_COMPILE);
glBegin(prim);
glVertex2f();
...
glVertex2f();
glEnd();
glEndList();

Then did:

glColor3f();
glCallList(42);

We'd map a vertex buffer as soon as we saw glColor3f but we'd never
actually write anything to it.  Note that the vertex position data
was put into a vertex buffer during display list compilation.

With this change, we delay mapping the vertex buffer until we actually
have a vertex to write to it (triggered by a glVertex() call).  In the
above case, we no longer map a vertex buffer when setting the color and
calling the list.

For drivers such as VMware's, reducing buffer mappings gives improved
performance.
