Really this should be set based on buffer format, not on color vs

Unlike GEN6, the bits of entry count are distributed like this
width = (entry_count & 0x0000007f); /* bits [6:0] */
height = (entry_count & 0x001fff80) >> 7; /* bits [20:7] */
depth = (entry_count & 0x7fe00000) >> 21; /* bits [30:21] */
The maximum entry count is still limited to 2^27.
This was noted while going over the PRM. No test is impacted, because
1<<20 (the bit that moved) is much larger than GL_UNIFORM_BLOCK_MAX_SIZE,
GL_MAX_TEXTURE_BUFFER_SIZE, or MAX_*_UNIFORM_COMPONENTS.

Previously, the only kind of ir_jump that would terminate a basic
block was "return". However, the other possible types of ir_jump
("break", "continue", and "discard") should terminate a basic block
too. This patch modifies basic block analysis so that it terminates a
basic block on any type of ir_jump, not just ir_return.

Running piglit with this was causing all sort of weird stuff happening
to my desktop (Chromium webpages become blank, Qt Creator flickered,
etc). I tracked this down to shared memory segment leakage when GL is
not shutdown properly. The segments can be seen running `ipcs` and
looking for nattch==0.
This changes fixes this by calling shmctl(IPC_RMID) soon after creation
(which does not remove the segment immediately, but simply marks it for
removal when no more processes are attached).
This matches src/mesa/drivers/x11/xm_buffer.c behaviour.
v2:
- move shmctl(IPC_RMID) after XShmAttach() for *BSD, per Chris Wilson
- remove stray debug printfs, spotted by Ian Romanick

The commit below exposed a bug in dri2_add_config.
commit 3998f8c6b5
Author: Ralf Jung <post@ralfj.de>
Date: Tue Apr 9 14:09:50 2013 +0200
egl/x11: Fix initialisation of swap_interval
This little code snippet near the bottom of dri2_add_config,
if (double_buffer) {
...
conf->base.MinSwapInterval = dri2_dpy->min_swap_interval;
conf->base.MaxSwapInterval = dri2_dpy->max_swap_interval;
}
it never did what it claimed to do. The assignment never changed the value
of conf->base.MaxSwapInterval, because dri2_dpy->max_swap_interval was,
until the above exposing commit, unitialized here. That is,
conf->base.MaxSwapInterval was 0 before and after assignment. Ditto for
the min swap interval.
Above the troublesome code snippet, the call to _eglFilterArray rejects
the config as unmatching if its swap interval bounds differ from the base
config's. Before the exposing commit, at the call to _eglFilterArray, the
swap interval bounds were always [0,0], and hence no config was rejected
due to swap interval.
After the exposing commit, _eglFilterArray incorrectly rejected some
configs, which prevented dri2_egl_config::dri_double_config from getting
set for the rejected config, which resulted in a NULL pointer getting
passed into dri2CreateNewDrawable, and then segfault.
The solution: set the swap interval bounds before _eglFilterArray.

_NEW_TRANSFORM_FEEDBACK is not used by core Mesa, so it can be removed.
Instead, an new private flag is added to i965 to serve the same purpose.
If you're new to this:
* When creating a context. you can set private dirty flags
in gl_context::DriverFlags, eg.:
ctx->DriverFlags.NewStateX = BRW_NEW_STATE_X;
* When StateX is changed, core Mesa does:
ctx->NewDriverState |= ctx->DriverFlags.NewStateX;
* When you have to draw, read and clear ctx->NewDriverState.
* Pros: not touching NewState, the driver decides the mapping between
GL states and hw state groups, unlimited number of flags in core Mesa
(still limited number of flags in the driver though)
