Dodji Seketeli 4b7e295b20 Bug 19596 - Incorrect exit status for incompatible ABI change 
The comparison engine doesn't take virtual offset changes into account
when deciding if a diff node carries an incompatible change.  This is
obviously an oversight.

Fixed thus.

	* include/abg-comparison.h (enum diff_category): Adjust the
	comment for enumerator VIRTUAL_MEMBER_CHANGE_CATEGORY; changes of
	this category are incompatible ABI changes.
	(corpus_diff::diff_stats::num_func_with_virtual_offset_changes):
	Declare new accessors.
	* src/abg-comparison.cc
	(corpus_diff::diff_stats::priv::num_func_with_virt_offset_changes):
	New data member.
	(corpus_diff::diff_stats::priv::priv): Initialize the new data
	member.
	(corpus_diff::diff_stats::num_func_with_virtual_offset_changes):
	Define new accessors.
	(corpus_diff::priv::apply_filters_and_compute_diff_stats): Use the
	new accessor to set the number of functions with virtual offset
	changes onto the stats data structure.
	(corpus_diff::has_incompatible_changes): Take functions with
	virtual offset changes into account.
 	* tests/test-abidiff-exit.cc: New test harness to test for exit
	codes of abidiff.
	* tests/Makefile.am: Build the new test harness runtestabidiff
	from the test-abidiff-exit.cc source file.
	* tests/data/test-abidiff-exit/test1-voffset-change-report0.txt:
	New reference test output.
	* tests/data/test-abidiff-exit/test1-voffset-change-v0.cc: New
	test input source code.
	* tests/data/test-abidiff-exit/test1-voffset-change-v0.o: New test input.
	* tests/data/test-abidiff-exit/test1-voffset-change-v1.cc: New
	test input source code.
	* tests/data/test-abidiff-exit/test1-voffset-change-v1.o: New test input.
	* tests/data/Makefile.am: tests/data/Makefile.am: Add the new test
	inputs above to the source distribution.
