1. add functions check kernel enable a ring or not.
2. add function gem_get_num_rings() to check how many rings kernel has
enable.
3. gem_ring_sync_loop.c will call gem_get_num_rings() directly instead
of original static fucntion get_number_rings().

clean warnings: Silence unused (or private) functions
I've clarified the functions now, and added the proper call from the
python script.
Time to get a regression tester for our tools?

forcewake: Add mmio code to do proper forcewake stuff for gen6
We lost the ability to do register access when either debugfs isn't
mounted, or when the driver isn't loaded. The latter can be beneficial
in debugging situations.
This patch will allow the driver to still do mmio (leaving forcewake
management up to the callers) provided that the i915 driver appears to
not be loaded (according to sysfs)
Requested by Jesse.

intel_reg_dumper: use intel_register_access_init/fini

It was previously printing ironlake_debug_regs and haswell_debug_regs.
Since ironlake_debug_regs contains a lot of registers that don't exist
on Haswell, running intel_reg_dumper on Haswell caused "unclaimed
register" messages. Now I've copied the existing registers from
ironlake_debug_regs to haswell_debug_regs, so we won't print the
registers that don't exist anymore.
Also removed DP_TP_STATUS_A since it doesn't exist.

autoconf can be configured to not generate a config.h but to give the
defines with command line arguments instead. In this case, there's no
config.h to include.
To work in both cases autoconf adds a HAVE_CONFIG_H define on the command
line to signal there's a config.h to include.

Using the same environment variable as libdrm so one doesn't have to
remember two different things. This is helpful to run a test under a
fake identity, to, say, dump an aub file.

The second digit was off by one, which meant we accidentally treated
GT(n) as GT(n-1). This also meant no support for GT1 at all.

In some environments, we don't really want to loop 100000 times or
allocate 152352621 buffers because it makes the tests too long to run.
This adds a way to specify "quick" values to reduce the time taken by
certain tests.

Everywhere else we search for a match based on an Intel display
device, so if the quick check of the fixed slot fails, fallback to
walking the PCI bus looking for a match.

To make these helpers as least invasive as possible simply initialize
the options with a getopt parser and let the control flow be steered
with a simple helper which gets the subtest name as an argument.
The only tricky part for using it is that the subtest check helper
doubles up as the conduit to enumerate tests (and in that mode
prevents any test from being run). It is therefore important that
nothing gets printed to stdout outside of these checks.

In the future, we may like to enable wc mapping of at least the GATT,
and so causing a conflict if we attempt to map the entire bar as uc-
here. Obviously we need a better fallback plan, but for the moment only
attempt to map the portion of the pci space that we use for register
access.
