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.

Due to the nature of accessing a tiled buffer in an untiled way, we
used to loop through the whole buffer all the time. Add a small
mechanism to just break in case we know we already wrote every pixel
we should have written.
On kms_frontbuffer_tracknig/fbc-2p-primscrn-pri-shrfb-draw-pwrite
(with a 3200x1800 primary screen and a 1920x1080 secondary screen), I
could reduce the runtime from ~7.53s to ~6.01s.

Don't forget to flush in case we're in the last iteration of the loop.
This fixes failures of kms_frontbuffer_tracking when used with
--use-small-modes on eDP monitors.

We need to test those pixel formats on the FBC code, so let's make
sure the drawing library works on them first.

If I have a program with the following:
igt_skip_on(i % 2 == 0);
igt_skip_on_f(i % 2 == 0, "i:%d\n", i);
igt_require(i % 2 == 0);
igt_require_f(i % 2 == 0, "i:%d\n", i);
then I'll get compiler error messages complaining about format
conversions related to the '%' character used in the mod operation. So
put the whole string as a %s argument to avoid interpreting '%' and
any other possible chars.

From Gen9, by default push constant command is not committed to the shader unit
untill the corresponding shader's BTP_* command is parsed. This is the
behaviour when set shader is enabled. This patch updates the batch to follow
this requirement otherwise it results in gpu hang.
Set shader need to be disabled if legacy behaviour is required.

Don't set the size of bindless surface state on rendercopy.
And as of doing so, take into account the workaround for setting
the command size.
This was tried during hunting for
https://bugs.freedesktop.org/show_bug.cgi?id=89959. But no
impact was found.

The commit "benchmarks: Do not install to system-wide bin/" changed
the benchmark file list from bin_PROGRAMS to benchmarks_PROGRAMS.
However Android.mk was not updated, resulting in IGT failing to
build for Android.
This commit adds that change. It also adds LOCAL_MODULE_PATH to
specify where the built benchmarks should be put.
v2: I discovered that the existing definitions of LOCAL_MODULE_PATH
were creating what should have been an invalid path. Not sure how it
was ever working previously, but fixed now.

A helpful function for when you want to read a whole debugfs file to a
string and don't want to worry about opening and closing file
descriptors and asserting buffer sizes.
We've been using this already for kms_frontbuffer_tracking and
kms_fbcon_fbt, so the only test with new code here is kms_fbc_crc.
Also notice that for kms_fbc_crc we had to increase the buffer size
since the file can sometimes be bigger than 64 bytes - depending on
the reason why FBC is disabled.
Of course, there are probably many other programs we can patch, but
I'm not doing this now.
v2: Add the macro to wrap sizeof() (Daniel).
v3: Add documentation for the macro too (Daniel).

If we are using a streaming GGTT write into the source, we need to
trigger an early fault in order to obtain a mappable offset. This is
required when later we start reserving execbuf object top-down to try
and avoid mappable space!

The gpgpu fill utility functions are used in separate test so it's
logical to keep them in separate file. This is similar to what media
spin test did in the past.
Functionally only gpgpu kernel changed. Send instruction payload size
was reduced. Since offset is incremented by 0x10 bytes there is no point
in using larger writes.

Exit immediately if the test is already exiting and igt_fail is called.

I just remembered that those Makefile.sources files where also
included by the Android build system, so we can't use automake's
conditionals in there.
So, we want to use GNU make's one. Unfortunately, after all those years,
GNU automake still doesn't do anything useful with GNU make's ifeq:
lib/Makefile.sources:66: error: else without if
automake will helpfully signal that the 'else' corresponding to the
'ifeq' doesn't have a corresponding 'if'. Well, yeah, thanks.
Fortunately, we can work around this by cunningly inserting a space
before 'ifeq', 'else' and 'endif' and fool automake's regex-based
checks.

When developing, it's quite annoying that the version changes every
commit, causing the library to be rebuild and every single binary
re-linked.
Add a config option to skip that.
I remember Ville asking for this "feature" as well.

https://en.wikipedia.org/wiki/Trimean
The trimean is a the most efficient 3-point L-estimator (estimator
of central tendency, i.e. average), even more robust than the
median at estimating the average of a sample population.

https://en.wikipedia.org/wiki/Interquartile_mean
The IQM is a truncated mean and so is very similar to the scoring
method used in sports that are evaluated by a panel of judges:
discard the lowest and the highest scores; calculate the mean
value of the remaining scores.
It's useful to hide outliers in measurements (due to cold cache etc),
without having to worry too much about the actual distribution.

Chris mentioned he wanted to be able to measure a variable "for one
second" and use igt_stats to store them. That's one case where we don't
know the number of data points upfront.
We should really support that, so here it is.
v2: Just free ->sorted when a new capacity is needed.
ensure_sorted_values() will then reallocate the array to the new
capacity on demand (Chris)
