The stack of batchbuffers is myth. In general there are only 2 levels of
stack for HEAD (ringbuffer, batchbuffer) and chaining up the batch
buffer just updates the lowest level of the stack. A BATCH_BUFFER_END at
any depth then returns to the ring.
So be creative and modify the batch buffer on the fly...

Rather than create a new scratch buffer every pass, import the original
as this provides stress upon less commonly trod paths (i.e. handling
objects with many vma) as well as many objects in general.

Emulate the behaviour of the second thread killing fd at random by
having a signal fire at a random time instead. Only one thread and so we
do not have the issue of accessing another valid handle on another fd
and so executing a blank buffer - triggering GPU hangs.

Currently, when trying to run i-g-t tests with piglit, it takes up
to 20s until the first test is executed.
The main reason is that gem_concurrent_all has ~500k subtests,
overkilling piglit.
This patch separates gem_concurrent_* tests from the rest of the tests,
creating two files test-list.txt and test-list-full.txt.
The piglit can now enumerate the i-g-t tests within a decent few seconds.
The second list could be used when trying to execute specific these tests.

The variable used as loop counter in the igt_fixture macro had
unspecified value from the setjmp(3) man page quoted below. Because of
that, in certain circumstances and with -O2 and -Os, the initialization
of that variable would be eliminated and the compiler would complain of
uninitialized usage. Below can be found a snippet that reproduces the
problem with GCC 5.3.1 and 4.9.3 and the errors as printed by 5.3.1.
"The compiler may optimize variables into registers, and longjmp() may
restore the values of other registers in addition to the stack pointer
and program counter. Consequently, the values of automatic variables
are unspecified after a call to longjmp() if they meet all the following
criteria:
· they are local to the function that made the corresponding setjmp(3)
call;
· their values are changed between the calls to setjmp(3) and
longjmp(); and
· they are not declared as volatile."
