intel: tools: import ImGui

We want to add a new UI tool to decode aub files. This will use the
Dear ImGui library to render its interface. The build of this UI
toolkit is conditional to -Dwith_tools=intel-ui which superseeds
-Dwith_tools=intel.

The main way to use ImGui is to embed its source code at a particular
revision. Most embedding projects have to do a bit of integration
which is really specific to one's project. In our case the only
modification is to include libepoxy. We also choose to use Gtk+3 for
the window system integration. As oppose to the previous previous
version of this patch using GLFW, Gtk+ is able to handle X11/Wayland
session as well as property DPI scaling on retina monitors.

intel: tools: aub_mem: reuse already mapped ppgtt buffers

When we map a PPGTT buffer into a continous address space of aubinator
to be able to inspect it, we currently add it to the list of BOs to
unmap once we're finished. An optimization we can apply it to look up
that list before trying to remap PPGTT buffers again (we already do
this for GGTT buffers).

We need to take some care before doing this because the list also
contains GGTT BOs. As GGTT & PPGTT are 2 different address spaces, we
can have matching addresses in both that point to different physical
locations.

This changes adds a flag on the elements of the list of mapped BOs to
differenciate between GGTT & PPGTT, which allows use to reuse that
list when looking up both address spaces.

python: Disable universal newlines

We are testing the behaviour of a tool, for different input files, each
one using a different newline sequence. ('\n' on UNIX, '\r\n' on
Windows, …)

Unfortunately, when opening a file in text mode, Python 3 will by
default enable the "universal newlines" mode, which means it replaces
all the known newline sequences by '\n'.

This (usually useful) behaviour breaks the tests, which are specifically
trying to handle files with newline sequences different from '\n'.

Disabling the universal newlines mode fixes the tests.

However, to keep the script compatible with both Python 2 and 3, we must
use the io.open() function instead of the open() builtin, as the latter
only knows about the `newline` argument on Python 3.
