We're little bit too enthusiastic in our initial attempt to lock all
available memory. Let's use the mlock probe from lib rather than trying
to lock everything that sysinfo.freeram has to offer.
Note that we're only tweaking the initial step - it's still possible
that we're going to get killed later on.
v2: Just increment lock instead of modifying addr passed to mlock

The initial mlock() is to check we can assigned all of memory to
ourselves -- without the kernel killing us. Move that check to an
isolated process so that we sacrifice the child.

When testing surface eviction we don't need that many surfaces as we
mlock surplus memory. Reducing the number of surfaces speeds up the test
and prevents a couple of integer overflow bugs.

Add a header that includes all the headers for the library. This allows
reorganisation of the library without affecting programs using it and
also simplifies the headers that need to be included to use the library.

igt_fork/igt_waitchildren already perform the magic required to raise
errors based on the exit error code of the child, so take advantage of
that and kill the overlycomplicated message passing!

The idea here is to check what happens when a large process requests
memory from us - we create and utilize a bunch of surfaces then have to
relinquish some but continue using the whole working set (so as to force
reloads).

The integer comparison macros give us better error output by including

It collides with the subtest naming convention glossary entry for swap.
Which makes the docbook xml stuff unhappy.

Introduce a new test to keep that we clean up on process exit (if the
userptr is busy or it has been gtt mmapped). This revealed a few bugs in
the existing tests so clean those up.

The goal is to only fill the aperture, not all of memory, so fine-tune
the computed number of surfaces, hopefully avoiding an integer overflow
in the process.

If we move the assertion from out of the callback, we can get a much
more useful error message.

And shovel all the various helpers in there.
Also move igt_set_vt_graphics_mode to igt_kms.h since the function is
implemented in igt_kms.c. And it fits better. I kinda missed this in
the prep work.

We allocate more surfaces than used in a single pass in order to stress
the eviction code between batches. The intent here is not to exercise
swapping, and we fail to check that there is enough swap+memory to hold
all our surfaces. So limit the number of surfaces we allocate to fit
into RAM, and then require that the number of surfaces we need for
testing is less than the number of surfaces we can allocate.
