Added Friulian translation
Bump to 0.17.1

Start a new development cycle.
Require GLib >= 2.37.6

We're going to need the latest snapshot.
tests: Use the new TAP support in GTest

Instead of using the old GLib test harness, we should use the newly
added TAP support and the TAP driver inside autotools.
path: Remove unused variable
Remove compile time GLib version check

We depend on a new version of GLib, so we can remove a bunch of old
version checks.
parser: Drop a pointless macro

The JSON_PARSER_GET_PRIVATE macro is pointless, now that we use the new
version of GLib.
parser: Use the proper GLib API to find test data files

Instead of our homegrown solution. This should fix the regression in the
installed tests case.

Original patch by: Colin Walters <walters@verbum.org>
parser: Fix all occurances of TESTS_DATA_DIR

And use g_test_build_filename().
Drop some more pointless GET_PRIVATE macros

We can use the autogenerated get_instance_private() function.
