When building OSMesa and xlib GL, the resulting OSMesa would be linked
against libGL instead of the internal mesa libraries. However, when
building with -fvisibility=hidden, some of the internal functions used
in OSMesa could not be resolved through libGL.
Instead, always build OSMesa standalone without linking against libGL.
This has the advantage that OSMesa is always built the same way, but it
means that disk space is wasted when libGL is installed since both
libraries will contain the internal objects.

If the default framebuffer is bound to <target>, then
<attachment> must be one of FRONT_LEFT, FRONT_RIGHT, BACK_LEFT,
BACK_RIGHT, AUXi, DEPTH_BUFFER, or STENCIL_BUFFER, identifying a
color buffer, the depth buffer, or the stencil buffer, and
<pname> may be FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE or
FRAMEBUFFER_ATTACHMENT_OBJECT_NAME.
as well as these <pname> values
FRAMEBUFFER_ATTACHMENT_RED_SIZE,
FRAMEBUFFER_ATTACHMENT_GREEN_SIZE,
FRAMEBUFFER_ATTACHMENT_BLUE_SIZE,
FRAMEBUFFER_ATTACHMENT_ALPHA_SIZE,
FRAMEBUFFER_ATTACHMENT_DEPTH_SIZE,
FRAMEBUFFER_ATTACHMENT_STENCIL_SIZE,
FRAMEBUFFER_ATTACHMENT_COMPONENT_TYPE, or
FRAMEBUFFER_ATTACHMENT_COLOR_ENCODING.

Keith came up with a new way of running the pipeline which involves passing
a few info structs around (for fetch, vertices and prims) and allows us
to correctly handle cases where we endup with multiple primitives generated
by the pipeline itself.
I have had a look at the libdrm sources and they just contain more or less
the same checking we do in macros, and begin_cs may realloc the CS buffer
if we overflow it, which never happens with r300g. So these are pretty
much useless.
There is a small but measurable performance increase by dropping the two
functions.
The previous implementation had issues with queries spanning over several
command streams as well as using a very large number of queries.
This fixes flickering in Enemy Territory: Quake Wars. The driver now renders
everything correctly in this game and the graphics is awesome.
The idea is to build a hardware command buffer for every CSO and memcpy
the buffer to a command stream at bind time (or dirty-state-emission time,
to be precise).
