Start using TAP

Convert {glib,gobject,gio}/tests to use the automake TAP driver
and test harness instead of gtester. To do so, we add a glib-tap.mk
that provides the same interface as glib.mk, except for the
reporting and coverage testing functionality. Eventually, we may
want to replace glib.mk with it. I've not yet converted the
toplevel tests/ directory, since it mixes gtestutils tests with
other binaries.

+# We support a fairly large range of possible variables.  It is expected that all types of files in a test suite
+# will belong in exactly one of the following variables.
+#
+# First, we support the usual automake suffixes, but in lowercase, with the customary meaning:
+#
+#   test_programs, test_scripts, test_data, test_ltlibraries
+#
+# The above are used to list files that are involved in both uninstalled and installed testing.  The
+# test_programs and test_scripts are taken to be actual testcases and will be run as part of the test suite.
+# Note that _data is always used with the nobase_ automake variable name to ensure that installed test data is
+# installed in the same way as it appears in the package layout.
+#
+# In order to mark a particular file as being only for one type of testing, use 'installed' or 'uninstalled',
+# like so:
+#
+#   installed_test_programs, uninstalled_test_programs
+#   installed_test_scripts, uninstalled_test_scripts
+#   installed_test_data, uninstalled_test_data
+#   installed_test_ltlibraries, uninstalled_test_ltlibraries
+#
+# Additionally, we support 'extra' infixes for programs and scripts.  This is used for support programs/scripts
+# that should not themselves be run as testcases (but exist to be used from other testcases):
+#
+#   test_extra_programs, installed_test_extra_programs, uninstalled_test_extra_programs
+#   test_extra_scripts, installed_test_extra_scripts, uninstalled_test_extra_scripts
+#
+# Additionally, for _scripts and _data, we support the customary dist_ prefix so that the named script or data
+# file automatically end up in the tarball.
+#
+#   dist_test_scripts, dist_test_data, dist_test_extra_scripts
+#   dist_installed_test_scripts, dist_installed_test_data, dist_installed_test_extra_scripts
+#   dist_uninstalled_test_scripts, dist_uninstalled_test_data, dist_uninstalled_test_extra_scripts
+#
+# Note that no file is automatically disted unless it appears in one of the dist_ variables.  This follows the
+# standard automake convention of not disting programs scripts or data by default.
+#
+# test_programs, test_scripts, uninstalled_test_programs and uninstalled_test_scripts (as well as their disted
+# variants) will be run as part of the in-tree 'make check'.  These are all assumed to be runnable under
+# gtester.  That's a bit strange for scripts, but it's possible.
