Dodji Seketeli ddc21ed73e Bug 19596 - Suppressed removed symbol changes still considered incompatible
Libabigail considers a removed function (or global variable) as being
an incompatible change, whether it has been suppressed or not.
Likewise, even if all function sub-type changes have been suppressed,
changed virtual offset on functions are still considered incompatible.

Thus, abidiff still returns an exit code that reflects an incompatible
change even if the removed symbol change was suppressed.

The rule should rather be that if incompatible changes have been
suppressed, abidiff (and the other tools) should take that into
account and not return an exit code that reflects incompatible
changes.

This patch implements that rule, at least for the incompatible changes
that are detected so far.

	* src/abg-comparison.cc (corpus_diff::has_incompatible_changes):
	Consider the *net* number of removed function and variable
	symbols.  Also, if all function sub-type changes have been
	suppressed, then no virtual offset change should be considered
	incompatible.
