cso: don't tell drivers to bind null samplers, sampler views
Before, the set_sampler_views() and restore_sampler_views() functions
used MAX2(old,new) to tell the driver how many samplers or sampler
views to set. This could result in cases such as:
pipe->set_fragment_sampler_views(pipe, 4, views={foo, bar, NULL, NULL})
Many/most gallium drivers would take this as-is and set
ctx->num_sampler_views=4 and ctx->sampler_views={foo, bar, NULL, NULL, ...}.
Later, loops over ctx->num_sampler_views would have to check for null
pointers. Worse, the number of sampler views and number of sampler CSOs
could get out of sync:
ctx->num_samplers = 2
ctx->samplers = {foo, bar, ...}
ctx->num_sampler_views = 4
ctx->sampler_views={Foo, Bar, NULL, NULL, ...}
So loops over the num_samplers could run into null sampler_views pointers
or vice versa.
This fixes a failed assertion in the SVGA driver when running the Mesa
engine demo in AA line mode (and possibly other cases).
It looks like all gallium drivers are careful to unreference views
and null-out sampler CSO pointers for the units beyond what's set
with the pipe::bind_x_sampler_states() and pipe::set_x_sampler_views()
functions.
I'll update the gallium docs to explain this as well.

scons: Eliminate libgcc_s_sjlj-1.dll dependency
Certain mingw32 cross compilers (e.g. RedHat's) defaults to use DLL gcc
runtime.
Given the main deliverable from this project are self-contained drivers,
which are loaded by any application, this dependency can cause havoc.

r600g: only set depth bit for hw accessible depth buffers.
If we get a sw accessible buffer like the S8 texture we end up
doing depth tracking on it when there is no need since we won't
ever bind it to the hardware. This leads to a sw fallback in the
transfer destruction which leads to and endless recusion loop
of fail in transfer destroy.

r600g: rework dirty / depth texture tracking.
this adds a flag to keep track of whether the depth texture structure
is the flushed texture or not, so we can avoid doing flushes when
we do a hw rendering from one to the other.
it also renames flushed to dirty_db which tracks if the DB copy
has been dirtied by being bound to the hw.
