These are used by multiple test cases, so make them shared.

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().

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.

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.

When looking at the pwrite/pread/wc performance, it is useful to judge
that against the performance of an ordinary CPU mmap.

We should get more kms tests soon, and not needing to copy-paste a
nice test pattern should be useful.
That establishes a firm depency of i-g-t on cairo over everything, but
I don't care so much about that.

Unfortunately this requires slab poisoning to catch anything :(
Also add a new helper to drmtest to get the available fence count.

This is meant to test the sysfs entry for showing rc6 residency in
milliseconds. Remember, sysfs is a permanent interface.
v2: use new get_card interface to try "all" devices
check rc6p and rc6pp in addition to rc6
v3: rename rc6_residency.c to sysfs_rc6_residency.c
print better error messages
skip test if rc6 isn't enabled
v4: update to new sysfs names

Currently all we see is gem_read: ret == 0 failed, where it would help
to see the errno and/or the ret.

MI_MEM_VIRTUAL actually means use global gtt now, not setting the bit
means use ppgtt. On previous gens, not setting the bits ment 'use
physical memory'. So what, the usual confusion.
Note that for some odd reasong this is broken on gen6, but only on the
bsd ring. Unexpected.

Some test that trash the aperture necessarily need to take forever, so
add a little progress indicator to keep worried minds at peace.

Lots of tests need to create havoc to LRUs in the kernel or otherwise
need to shuffle things around a bit. So make a small array permutation
function available.

Some tests are higly timing dependent and others carelessly leave
active buffers behind. So add a helper to quiescent the gpu and call
it unconditionally when opening an fd in a vain attempt to make all
this race-condition hitting more scientifically sound.

Way too much copy-pasting going on here.
Also fix a compiler warnings in gem_stress while fixup things up.
