Many tests have preconditions like a correct version of the test submodule
or installed traineddata files at the right location. They fail or even
crash if those preconditions are not met.
The latest version of Googletest supports skipping single tests with
GTEST_SKIP which is used here to skip tests in applybox_test when
tessdata/eng.traineddata is missing.

Some unit tests use code from training. Those tests are enabled
if training is enabled, so for that case the "check" target
depends on the "training" target.

tesstrain_utils.sh sets the shell flag -e, so it exits immediately
if a command exits with a non-zero status.
The following command returns a non-zero status as soon as counter is a
multiple of par_factor (par_factor=8, that means as soon as 8 fonts or
images are processed):
let rem=counter%par_factor
The new code fixes this undesired exit.

pango_coverage_get and pango_coverage_unref should not be called
with coverage == nullptr.
pango_font_get_coverage should not be called with font == nullptr.
Otherwise Pango prints runtime error messages:
(process:12657): Pango-CRITICAL **: pango_coverage_get: assertion 'coverage != NULL' failed
(process:12657): Pango-CRITICAL **: pango_coverage_unref: assertion 'coverage != NULL' failed
(process:12657): Pango-CRITICAL **: pango_font_get_coverage: assertion 'font != NULL' failed
(process:12657): GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
Typically those errors occur if a required font is not installed,
so this can be a quite common error.
Fix also a potential resource leak in PangoFontInfo::CoversUTF8Text.

Get unicharset and wordlist files from test/testing and use the latest
test submodule which provides those files.

Commit d36231e3e4 did not distinguish
between AVX and AVX2, so AVX2 code was enabled for IntSimdMatrix
even when only AVX was supported.
This resulted in an illegal instruction.
